+

At mCaptcha, we believe in digital freedom and privacy and so we built a proof-of-work based CAPTCHA system that doesn’t track. Seriously, no tracking. But that isn’t the killer feature, our system doesn’t require the user to pick cars or ID sidewalks — our system does it’s -thing(usually at the click of a button) and gets out of the way.

Philosophy

Man has has come so far only because our ancestors chose to share their knowledge with others. If everything was labeled intellectual property, we might still be stuck in Stone Age. The idea of intellectual property is alien to us. For this reason, all of our source code is freely -available(both as in freedom and beers) at our GitHub.

+

Hello and welcome to the first edition of the monthly report!

+

I believe free software like mCaptcha is critical to a healthy internet but being a one-person show, there’s hardly any accountability in the way software is built. I hope, through monthly reports, I can explain the logic and intentions behind decisions taken in the development -process.

This month, the following things were accomplished:

1. Full LibreJS Compliance

The CAPTCHA widget and the admin dashboard are 100% LibreJS compliant!

It should also detect the Apache licensing but I probably botched it up.

2. JavaScript PolyFill

mCaptcha relied on a WebAssembly(WASM) port of the proof-of-work algorithm used in mCaptcha. This meanth browsers without WASM support -couldn’t process CAPTCHAs. This month, a pure JavaScript(TypeScript, -technically) implementation was released to -overcome this limitation.

3. Integration libraries for Vanilla JS, React and Svelte:

4. Beginner friendly CAPTCHA configuration options.

To help webmasters correctly configure difficult factors, we are building a feedback loop which would gather performance statistics from voluntary mCaptcha installations and make them available to other mCaptcha installations. The performance statistics can be used by all mCaptcha instances to automatically optimize an installation. We are -calling this the mCaptcha net.

Ideas for Commercial Operations

+

Commercial operations will take a while longer(end of 2022, most +probably). For Hostea, I wrote a dashboard with payments capabilities(via Stripe) so that experience will help me do the same for mCaptcha. Working on Hostea has been truly enlightening: it’s probably the first effort to offer a fully libre, infrastructure-as-code and payments software included, hosting service. I would like to do the same for mCaptcha so that service that I setup goes rogue or if someone wants to offer mCaptcha hosted services, they can replicate my set up -with ease.

+

But the commercial offering will at no point force me or future maintainers turn mCaptcha into adopting a non-free license like the -Server Side Public +Server Side Public License. So the following months will see administrative changes within mCaptcha to device mechanisms to prevent me or any future party with influence in -mCaptcha development from hurting the project by it non-free.

Hostea is also an experiment in Free Software commercial operations, so +mCaptcha development from hurting the project by it non-free.

+

Hostea is also an experiment in Free Software commercial operations, so naturally I’m highly impressed by the ideas that are being discussed there. mCaptcha, too, will borrow ideas from that project to make its -development economically sustainable.

Hello and welcome to the May 2022 edition of the monthly report!

mCaptcha, for a while was showing all the signs of a dead project: no commits on the repositories and no monthly updates. But the project -is far from dead!

+

Python bindings to mCaptcha PoW

+

pow_py contains bindings to +pow_sha256, the +proof-of-work library that mCaptcha uses. For the uninitiated, the bindings allow for python -programs to automatically solve mCaptcha.

So if you are writing a script to do some chore on your favourite +programs to automatically solve mCaptcha.

So if you are writing a script to do some chore on your favourite website that is protected by mCaptcha, you can now solve the mCaptcha -automatically from within the program.

Here’s an example:

- 6# get the sitekey that is used in the mCaptcha protected form
- 7SITEKEY = os.getenv("MCAPTCHA_CAPTCHA_SITEKEY")

- 9MCAPTCHA_HOST = os.getenv("MCAPTCHA_CAPTCHA_HOST")

-13VERIFY_POW_ROUTE = f"{MCAPTCHA_HOST}/api/v1/pow/verify"
-14

-16
-17    # get challenge configuration

-23    config = mcaptcha_pow_py.PoWConfig(challenge_config["salt"])
-24    pow_string = challenge_config["string"]
-25    pow_difficulty_factor = challenge_config["difficulty_factor"]
-26
-27    # generate work
-28    work = config.work(pow_string, pow_difficulty_factor)
-29

mCaptcha uses a +proof-of-work(PoW) mechanism to rate limit users or potential bots. In order for this to be effective, the PoW should be configured properly. The difficulty requirement can’t be too high, as it could cause accessibility issues on the client-side while at the same time, it shouldn’t be too low, as it -wouldn’t offer proper protection against bots.

Malicious bots(the ones that wreak havoc), run native code which is capable of running in a multi-threaded context. This creates an unfair advantage for crackers using these bots over legitimate users, who -usually use browsers to access a website.

I wanted to see how much of an advantage a native program would have -over our WASM library.

So I wrote these to compare native and WASM performances:

We are mCaptcha. We build kickass CAPTCHA systems that give (DDoS) attackers a run for their money. And we do all of this without tracking your users. Oh and did I mention our UX is great?

+

At mCaptcha, we believe in digital freedom and privacy and so we built a +proof-of-work based CAPTCHA system that doesn’t track. Seriously, no tracking. But that isn’t the killer feature, our system doesn’t require the user to pick cars or ID sidewalks — our system does it’s thing(usually -at the click of a button) and gets out of the way.

How does it work?

mCaptcha uses SHA256 based proof-of-work(PoW) to rate limit users.

When a user wants to do something on an mCaptcha-protected website,

  1. they will have to generate proof-of-work(a bunch of math that will -takes time to compute) and submit it to mCaptcha.

  2. We’ll validate the proof:

  • if validation is unsuccessful, they will be prevented from accessing -the destination website
  • if validation is successful, read on,

  1. They will be issued a token that should be submit along with the -request/form to the destination website.

  2. The destination website validates the submitted token with -mCaptcha before processing the request.

The whole process is automated from the user’s point of view. All they -have to do is click on a button to initiate the process.

Okay, but what about bad actors?

+

mCaptcha makes interacting with websites (computationally)expensive for the user. A well-behaving user will experience a slight delay(no delay when under moderate load to 2-3 seconds when under attack; PoW difficulty is variable) but if someone wants to hammer your site, they will have to do more work to send requests than your server you will have to do to respond -to their request.

Why use mCaptcha?

  • Free software, privacy focused
  • Seamless UX — No more annoying CAPTCHAs!
  • IP address independent: your users are behind a NAT? We got you covered!
  • Automatic bot throttling
  • Resistant to replay attacks: proof-of-work configurations have short lifetimes(30s) and can be used only once. If a user submits a PoW to an already used configuration or an expired one, their proof will be rejected.

How to migrate?

Our client libraries are mostly compatible with reCAPTCHA and hCaptcha. -A detailed guide will be published soon.

This is the code that links mCaptcha with your website’s frontend code. It creates an iframe containing the mCaptcha widget and injects the -received verification proof token into a hidden input field.

Support is available for various frameworks, see -mCaptcha/glue for the full list.

For frameworks without official support, a low-level library, -@mcaptcha/core-glue, -can be used to implement support.

Widget Program

+

This part is served by the mCaptcha backend. It fetches PoW config from the backend, generates proof and submits it for verification. If verification is successful, it sends a message containing the verification proof token to the parent window, assuming it’s loaded as -an iframe.

WebAssembly bindings(mCaptcha/pow_wasm) are available for the main rust library(mCaptcha/pow_sha256).

Deploy bare metal

+

Bare metal deployment is tedious, most of this will be automated with a script in the future.

+

1. Install Database

+

The following databases are supported:

+
    +
  1. Postgres
    2. +
  2. MariaDB
    3. +
+

Please install the database of your choice. Then:

+
    +
  1. Create new database user for mCaptcha
    2. +
  2. Create new database for mCaptcha
    3. +
+

mCaptcha binary has migrations baked-in and is applied on start up. The +choice of database is described using the scheme of the database URL. For +instance:

+
    +
  1. Postgres: postgres://mcaptcha:password@localhost:5432/mcaptcha
    2. +
  2. Mariadb: mysql://mcaptcha:password@localhost:3306/mcaptcha
    3. +
+

2. Optionally, install mCaptcha/cache

+

We recommend this for larger instances. For single-user instances or for +instances that protect personal websites, we recommend using the +internal cache system. To do so, please comment out the +redis section of the configuration file.

+

Please see mCaptcha/cache for more details.

+

3. Install mCaptcha

+

3.1 Install from source

+

To build mcaptcha, you need the following dependencies:

+
    +
  1. rust
    2. +
  2. node(v20)
    3. +
  3. yarn(JavaScript package manager)
    4. +
  4. make
    5. +
+

With all dependencies installed, run:

+
make dev-env && make release
+

And the following commands to install the compiled binary:

+
sudo cp ./target/release/mcaptcha /usr/bin/ && \
+	mkdir sudo /etc/mcaptcha && \
+	sudo cp config/default.toml /etc/mcaptcha/config.toml
+

3.2 Install pre-compiled binary

+

i. Download assets

+
wget https://dl.mcaptcha.org/mcaptcha/mCaptcha/master/mcaptcha-master-linux-amd64.tar.gz.asc
+wget https://dl.mcaptcha.org/mcaptcha/mCaptcha/master/mcaptcha-master-linux-amd64.tar.gz.sha256
+wget https://dl.mcaptcha.org/mcaptcha/mCaptcha/master/mcaptcha-master-linux-amd64.tar.gz
+

ii Verify checksum

+
sha256sum -c mcaptcha-master-linux-amd64.tar.gz.sha256
+

iii Verify GPG signature

+

All mcaptcha binaries are signed with our GPG +key. +Please verify signatures to verify authenticity.

+
gpg --keyserver keyserver.ubuntu.com --recv 73DAC973A9ADBB9ADCB5CDC4595A08135BA9FF73
+gpg --verify mcaptcha-master-linux-amd64.tar.gz.asc
+

iv. Install

+
tar -xvzf mcaptcha-master-linux-amd64.tar.gz \
+  && sudo cp mcaptcha-master-linux-amd64/mcaptcha /usr/local/bin \
+  && sudo mkdir /etc/mcaptcha \
+  && sudo cp mcaptcha-master-linux-amd64/config.toml /etc/mcaptcha/
+

4. Configuration

+

mCaptcha is highly configurable.

+

Configuration is applied/merged in the following order:

+
    +
  1. path to configuration file passed in via MCAPTCHA_CONFIG
    2. +
  2. ./config/default.toml
    3. +
  3. /etc/mcaptcha/config.toml
    4. +
  4. environment variables. Please see +here for a full list of environment variables.
    5. +
+

5. Systemd service configuration:

+
    +
  1. Copy the following to /etc/systemd/system/mcaptcha.service:
    2. +
+
[Unit]
+Description=mCaptcha: a CAPTCHA system that gives attackers a run for their money
+
+[Service]
+Type=simple
+User=mcaptcha
+ExecStart=/usr/bin/mcaptcha
+Restart=on-failure

+Wants=network-online.target
+Wants=network-online.target
+Requires=postgresql.service
+After=syslog.target
+
+[Install]
+WantedBy=multi-user.target
+
    +
  1. Enable service:
    2. +
+
sudo systemctl daemon-reload && \
+	sudo systemctl enable mcaptcha && \ # Auto startup during boot
+	sudo systemctl start mcaptcha
+

6. Install and configure Nginx

+

mCaptcha doesn’t implement SSL yet. Please use a reverse proxy like +Nginx to add SSL to your deployment. Here’s an example virtual host +configuration for Nginx:

+
server {
+  server_name <your mcaptcha hostname>;
+	listen 80;
+	listen [::]:80;
+
+	location / {
+		proxy_pass http://127.0.0.1:<mcaptcha_port>;
+		proxy_set_header Host $host;
+    proxy_set_header Host $host;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection "upgrade";
+    proxy_set_header X-Forwarded-For $remote_addr;
+    proxy_set_header X-Forwarded-Proto $scheme;
+	}
+
+}

Database and cache

mCaptcha server requires dependencies like a Postgres database and a Redis cache

Notes

Database

  • Database migrations are baked into the server binary so don’t worry -about them.

  • When compiling from source, unset database configuration(comment out -database configuration/ unset relevant environment variables). -mCaptcha uses sqlx database client -library which checks SQL queries at compile time. So if you are starting -with a fresh database without migrations applied, compilation will fail.

Redis

  • Redis is an optional dependency. Currently, the non-Redis configuration -doesn’t persist CAPTCHA heat. So if there’s a systems failure, CAPTCHA -heat will be reset and visitor count will start from 0. For small -installations, this should post a problem as heat is short lived and is -reset anyways at cool down period.

  • mCaptcha uses a custom Redis module called -cache to overcome some of Redis' -limitations.

Instructions

Once again, there are two ways to go about this:

  1. Docker
  2. Bare metal

Docker

Database

Download and run Postgres

1docker create --name mcaptcha-postgres \
-2  -e POSTGRES_PASSWORD=<database-password> \
-3  -p 5432:5432 \
-4  postgres && docker start mcaptcha-postgres
-

Redis

1docker create --name mcaptcha-cache \
-2  -p 6379:6379 \
-3  mcaptcha/cache && docker start mcaptcha-cache
-

See mCaptcha/cache for more -details.

1. Install Postgres if you don’t have it already.

For Debian based distributions:

1sudo apt install postgres
-

2. Create new user for running mCaptcha

1$ sudo useradd -b /srv -m -s /usr/bin/bash mcaptcha
-

3. Create new user in Postgres

1$ sudo -iu postgres # switch to `postgres` user
-2$ psql
-3postgres=#  CREATE USER mcaptcha WITH PASSWORD 'my super long password and yes you need single quote';
-4$  createdb -O mcaptcha mcaptcha # create db 'mcaptcha' with 'mcaptcha' as owner
-

4. Install mCaptcha/cache

See mCaptcha/cache for more -details.

Using Docker

With Docker

1. Configure

mcaptcha is highly configurable.

Configuration is applied/merged in the following order:

  1. path to configuration file passed in via MCAPTCHA_CONFIG
  2. ./config/default.toml
  3. /etc/mcaptcha/config.toml
  4. environment variables.

See -CONFIGURATION.md -for configurable options.

2. Run image

If you have already have a Postgres instance running, then:

1docker run -p <host-machine-port>:<port-in-configuration-file> \
-2	--add-host=database:<database-ip-addrss> \
-3	-e RUST_LOG=debug \
-4	-e DATABASE_URL="postgres://<db-user>:<db-password>@database:<db-port>/<db-name>" \
-5	mcaptcha/mcaptcha:latest
-

If you don’t have a Postgres instance running, you can either install -one using a package manager or launch one with docker. A docker-compose -configuration is available that will launch both -a database instance mcaptcha instance.

With docker-compose

  1. Follow steps above to build docker image.

  2. Set database password docker-compose configuration.

  3. Launch network

1docker-compose up -d

Pass mCaptcha challenge

+

The CLI tool requires details about the challenge to work on it. The +tool can be used in three different modes compute challenge:

+
    +
  1. Protected Page: Compute mCaptcha challenge for the CAPTCHA at a +protected page
    2. +
  2. Widget URL: Compute PoW for captcha at widget URL
    3. +
  3. (Developer mode) Offline: Computes PoW over given CAPTCHA parameters
    4. +
+

From protected page URL

+

The most convenient mode: copy the URL of the webpage which has the mCaptcha widget (example: showcase.mcaptcha.org) and run the CLI tool with it to get an authorization code: -Compute challenge using the URL

Configuring Difficulty Factor

+

+

mCaptcha is highly responsive to detecting DDoS attacks. Admins are +advised to take advantage of it by setting low difficulty factors for normal traffic levels -for their website.

Lowest advisable difficulty factor is 5000.

For instance, if it is normal for my website to get 2000 requests for -every 30 seconds, I will set a cool +for their website.

+

Lowest advisable difficulty factor is 5000.

For instance, if it is normal for my website to get 2000 requests for +every 30 seconds, I will set a cool down period of 30 seconds and the -first level of difficulty configuration will have a visitor threshold of 2000 with a -difficulty factor of 5000.

There are two modes to setting difficulty factor for your website on -mCaptcha:

Easy mode asks a few basic statistics about your website and generates a +first level of difficulty configuration will have a visitor threshold of 2000 with a +difficulty factor of 5000.

There are two modes to setting difficulty factor for your website on +mCaptcha:

Easy option

Easy mode asks a few basic statistics about your website and generates a configuration that should work for your website. Currently, easy mode is guided by assumptions on suitable difficulty factors to protect a -website but it will be fine-tuned as mCaptcha sees more deployment.

Configuration generated by easy mode can be tweaked later using the -advance mode, as you become more familiar with how mCaptcha works.

Advance mode gives the admin granular control over how mCaptcha behaves on their website. It has options to set the difficulty factor for each level of traffic(or visitor threshold, in mCaptcha speak), fully taking -advantage of mCaptcha’s variable difficulty factor feature.

For instance, if it is normal for a website to get 200 requests over 30 seconds, then setting a very low difficulty factor for a visitor threshold of 200 and a cool down period of 30 seconds will allow the users to pass through without waiting on the CAPTCHA. But if 1000 requests over 30 seconds will bring down the service, then the admin can configure increasing levels of difficulty factor of increasing traffic levels, effectively rate limiting its users and protecting the -underlying website.

    When a visitor solves the CAPTCHA and sends their solution to an mCaptcha instance, the solution will be verified for correctness. If the -solution is correct, mCaptcha will return a single use authorization token.

    This authorization token should be attached to the visitor’s requited to the +solution is correct, mCaptcha will return a single use authorization token.

    +

    This authorization token should be attached to the visitor’s requited to the protected service and the protected service should validity of the authorization token with the mCaptcha instance and only allow authorization to -protected resource if the authorization token is valid.

    Cooldown Period

    mCaptcha implements leaky bucket algorithm to measure +protected resource if the authorization token is valid.

    +

    Cooldown Period

    +

    mCaptcha implements leaky bucket algorithm to measure current traffic levels. Cooldown period specifies the leak or the time -after which a visitor addition is decremented.

    For instance, if initial traffic level is 0 and a user visits one +after which a visitor addition is decremented.

    +

    For instance, if initial traffic level is 0 and a user visits one second later, the traffic level will be incremented to 1. Now, if the cooldown period is set to 30 seconds, the traffic level will be decremented after 30 seconds. So after 30 seconds, the traffic level will -go from 1 to 0.

    Difficulty Factor

    Difficulty factor determines the time it takes to solve a CAPTCHA. The +go from 1 to 0.

    +

    Difficulty Factor

    +

    Difficulty factor determines the time it takes to solve a CAPTCHA. The higher the difficulty factor, the longer it will take to generate a -proof of work for it to solve the CAPTCHA.

    mCaptcha’s proof of work based mechanism makes it highly accessible to +proof of work for it to solve the CAPTCHA.

    +

    mCaptcha’s proof of work based mechanism makes it highly accessible to people with special needs but it is important to choose the difficulty factor with care as very high difficulty factors will make the CAPTCHA -inaccessible to users on slow devices.

    Sitekey

    Site key is a unique identifier associated with CAPTCHA configurations +inaccessible to users on slow devices.

    +

    Sitekey

    +

    Site key is a unique identifier associated with CAPTCHA configurations created on mCaptcha. It is required to integrate a CAPTCHA with your -website.

    Visitor Threshold

    mCaptcha’s variable difficulty factor mechanism requires a website’s traffic +website.

    +

    Visitor Threshold

    +

    mCaptcha’s variable difficulty factor mechanism requires a website’s traffic statistics be split into levels, so that it can deploy the right -difficulty factor for each level.

    Visitor threshold is used to traffic into levels and mCaptcha accepts a +difficulty factor for each level.

    +

    Visitor threshold is used to traffic into levels and mCaptcha accepts a difficulty configuration for each of these levels. When current traffic exceeds a difficulty factor, mCaptcha will increase the difficulty -factor to the next configured level.

    For instance, consider the configuration given below:

    • Cool down period: 30 seconds
    LevelDifficulty FactorVisitor Threshold
    15,0002,000
    250,0005,000
    3500,00010,000
    45,000,00015,000

    If the website sees 2,000 requests in a 30 second window, level 1 +factor to the next configured level.

    +

    For instance, consider the configuration given below:

    +
      +
    • Cool down period: 30 seconds
      • +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    LevelDifficulty FactorVisitor Threshold
    15,0002,000
    250,0005,000
    3500,00010,000
    45,000,00015,000
    +

    If the website sees 2,000 requests in a 30 second window, level 1 difficulty factor(5,000) will be deployed. If the traffic increases to 5,000 requests in a 30 second window, then difficulty factor will be upgraded to level 2(50,000). Likewise 10,000 and 15,000 requests over 30 seconds will result in difficulty factor being upgraded to 500,000 and -5,000,000 respectively.

    Visitor threshold is how mCaptcha determines which difficulty factor +5,000,000 respectively.

    +

    Visitor threshold is how mCaptcha determines which difficulty factor level to deploy. mCaptcha uses leaky bucket algorithm to keep the visitor threshold constantly updated within the configured cool down period. So, at any given moment the, the current visitor level will be -the amount of traffic that was served in the cool down period specified.

In this guide we’ll +explore how to install mCaptcha on your website. The end result will be +something like this, on your website:

    +
    + A registration form with mCaptcha widget installed + +
    +

    For the purpose of this demo, we will be using +demo.mcaptcha.org, a demo instance running +in @realaravinth’s bedroom(for this same reason, it shouldn’t be used +for anything serious)

    +

    1. Create an account and sign into the mCaptcha dashboard

    +

    Head over to demo.mcaptcha.org and +create an account. When ready, sign in.

    +

    2. Create new site key

    +

    A site key is how a new CAPTCHA is configured within mCaptcha. To create +a new site key, click on “New Site” button in the dashboard.

    +
    + mCaptcha dashboard with the 'new site key' button highlighted + +
    +

    There are two options to create a new site key, easy and advanced. We +are going to use the easy mode in this tutorial. If you are interested +in learning more about the advance mode, please see here.

    +

    Fill the form and submit it.

    +
    + mCaptcha dashboard with the 'new site key' form in easy mode, with details filled in + +
    + +

    Submitting the form will take you to a page where site key configuration +can be viewed. “View deployment” link will display CAPTCHA widget with +the supplied configuration. Click on it and grab the widget link.

    +

    4. Install mCaptcha on your website

    +

    Integration support is available for some frontend JavaScript +frameworks. To see full list of supported frameworks, please see +here.

    +

    There are two options to use the integration library to integrate +mCaptcha on your website:

    +
      +
    1. Serve the integration library yourself
      2. +
    2. Use a CDN like unpkg.com
      3. +
    +

    In this tutorial, we’ll be using the CDN.

    +

    Pasting the following snippet on the page, within the form that requires to be protected +will load the mCaptcha widget with the configuration supplied. Be sure +to replace Your {{paste your widget link}} with the link obtained from +the previous step.

    +
     1<label
+ 2  data-mcaptcha_url="{{paste your widget link here}}"
+ 3  for="mcaptcha__token"
+ 4  id="mcaptcha__token-label"
+ 5>
+ 6  mCaptcha authorization token.
+ 7  <a
+ 8    href="https://mcaptcha.org/docs/user-manual/how-to-mcaptcha-without-js/"
+ 9    >Instructions</a
+10  >.
+11  <input type="text" name="mcaptcha__token" id="mcaptcha__token" />
+12</label>
+13<div id="mcaptcha__widget-container"></div>
+14<script src="https://unpkg.com/@mcaptcha/vanilla-glue@0.1.0-rc2/dist/index.js"></script>
+

    A full example is available +here.

    +

    5. Configure backend to authenticate CAPTCHA tokens

    +
      +
    1. +

      Get access token from the user’s +form submission payload. The access token will be associated with a +parameter called mcaptcha__token.

      +
      1 mcaptcha_token = request.form["mcaptcha__token"]
+
      2. +
    2. +

      Validate access token with mCaptcha instance

      +
      3. +
    +
     1payload = {
+ 2    "token": mcaptcha_token,
+ 3    "key": mcaptcha_sitekey, # captcha site key
+ 4    # mCaptcha account secret; available in settings
+ 5    "secret": mcaptcha_account_secret,
+ 6}
+ 7resp = requests.post(
+ 8    "https://demo.mcaptha.org/api/v1/pow/siteverify", json=payload
+ 9)
+10resp = resp.json()
+
      +
    1. If access token is valid, allow access to protected resource or deny +access.
      2. +
    +
    1 if resp["valid"] == False:
+2     return "invalid captcha", 400
+3 else:
+4     return allow_access_to_protected_resource(request.form)
+

    Please see here for a complete Flask example and here for an Actix +Web example.

    +

    Congratulations, mCaptcha is now integrated with your website!

    +`},{id:1,href:"/docs/webmasters/configuring-difficulty-factor/",title:"Configuring Difficulty Factor",description:"mCaptcha has options to configure its proof of work engine behavior, this page explains how to determine difficulty facotrs that work best for your website!",content:`

    mCaptcha is highly responsive to detecting DDoS attacks. Admins are +advised to take advantage of it by setting low difficulty +factors for normal traffic levels +for their website.

    +

    Lowest advisable difficulty factor is 5000.

    +

    For instance, if it is normal for my website to get 2000 requests for +every 30 seconds, I will set a cool +down period of 30 seconds and the +first level of difficulty configuration will have a visitor threshold of 2000 with a +difficulty factor of 5000.

    +

    There are two modes to setting difficulty factor for your website on +mCaptcha:

    +

    Easy option

    +

    Easy mode asks a few basic statistics about your website and generates a +configuration that should work for your website. Currently, easy mode is +guided by assumptions on suitable difficulty factors to protect a +website but it will be fine-tuned as mCaptcha sees more deployment.

    +

    Configuration generated by easy mode can be tweaked later using the +advance mode, as you become more familiar with how mCaptcha works.

    +
    + new sitekey form in easy mode + +
    +

    Advance option

    +

    Advance mode gives the admin granular control over how mCaptcha behaves +on their website. It has options to set the difficulty factor for each +level of traffic(or visitor threshold, in mCaptcha speak), fully taking +advantage of mCaptcha’s variable difficulty factor feature.

    +

    For instance, if it is normal for a website to get 200 requests over 30 +seconds, then setting a very low difficulty factor for a visitor +threshold of 200 and a cool down period of 30 seconds will allow the +users to pass through without waiting on the CAPTCHA. But if 1000 +requests over 30 seconds will bring down the service, then the admin can +configure increasing levels of difficulty factor of increasing traffic +levels, effectively rate limiting its users and protecting the +underlying website.

    Get started

    +

    There are two main ways to self-host mCaptcha:

    +
      +
    1. Bare metal
      2. +
    2. With Docker
      3. +
    3. With Ansible
      4. +
    +`},{id:3,href:"/docs/self-hosting/bare-metal/",title:"Deploy bare metal",description:"Bare metal deployment is tedious, most of this will be automated with a script in the future.",content:`

    1. Install Database

    +

    The following databases are supported:

    +
      +
    1. Postgres
      2. +
    2. MariaDB
      3. +
    +

    Please install the database of your choice. Then:

    +
      +
    1. Create new database user for mCaptcha
      2. +
    2. Create new database for mCaptcha
      3. +
    +

    mCaptcha binary has migrations baked-in and is applied on start up. The +choice of database is described using the scheme of the database URL. For +instance:

    +
      +
    1. Postgres: postgres://mcaptcha:password@localhost:5432/mcaptcha
      2. +
    2. Mariadb: mysql://mcaptcha:password@localhost:3306/mcaptcha
      3. +
    +

    2. Optionally, install mCaptcha/cache

    +

    We recommend this for larger instances. For single-user instances or for +instances that protect personal websites, we recommend using the +internal cache system. To do so, please comment out the +redis section of the configuration file.

    +

    Please see mCaptcha/cache for more details.

    +

    3. Install mCaptcha

    +

+  && sudo cp mcaptcha-master-linux-amd64/mcaptcha /usr/local/bin \\
+  && sudo mkdir /etc/mcaptcha \\
+  && sudo cp mcaptcha-master-linux-amd64/config.toml /etc/mcaptcha/
+

    4. Configuration

    +

    mCaptcha is highly configurable.

    +

    Configuration is applied/merged in the following order:

    +
      +
    1. path to configuration file passed in via MCAPTCHA_CONFIG
      2. +
    2. ./config/default.toml
      3. +
    3. /etc/mcaptcha/config.toml
      4. +
    4. environment variables. Please see +here for a full list of environment variables.
      5. +
    +

    5. Systemd service configuration:

    +
      +
    1. Copy the following to /etc/systemd/system/mcaptcha.service:
      2. +
    +

    Instructions

    +

    Installation

    +
      +
    1. Clone the repository:
      2. +
    +
    1git clone https://git.batsense.net/mCaptcha/iac && cd iac
+
      +
    1. +

      Create inventory file. You should have SSH access to the remote +machine, and the user must have sudo privileges. Example inventory +file:

      +
      1[mcaptcha_hosts]
+2"mcaptcha_hosts"
+3<node name> ansible_host=<node IP> ansible_user=<remote username>
+

      It is important that the group name be mcaptcha_hosts.

      +
      2. +
    2. +

      Configure installation by editing ansible/vars/mcaptcha/vars.yml. Most parameters have defaults, and the required parameters are annotated.

      +
      3. +
    3. +

      Run playbook:

      +
      4. +

    With Docker

    +

    1. Configure

    +

    mcaptcha is highly configurable.

    +

    Configuration is applied/merged in the following order:

    +
      +
    1. path to configuration file passed in via MCAPTCHA_CONFIG
      2. +
    2. ./config/default.toml
      3. +
    3. /etc/mcaptcha/config.toml
      4. +
    4. environment variables.
      5. +
    +

    See +CONFIGURATION.md +for configurable options.

    +

    2. Run image

    +

    If you have already have a Postgres instance running, then:

    +
    docker run -p <host-machine-port>:<port-in-configuration-file> \\
+	--add-host=database:<database-ip-addrss> \\
+	-e RUST_LOG=debug \\
+	-e DATABASE_URL="postgres://<db-user>:<db-password>@database:<db-port>/<db-name>" \\
+	mcaptcha/mcaptcha:latest
+

    If you don’t have a Postgres instance running, you can either install +one using a package manager or launch one with docker.

    +

    With docker-compose

    +
      +
    1. Download docker-compose file and the configuration file:
      2. +
    +
    wget https://raw.githubusercontent.com/mCaptcha/mCaptcha/master/.env.docker-compose

    The browser part of mCaptcha is divided into three components.

    +
      +
    • Glue code
      • +
    • Widget program
      • +
    • Proof-of-Work libraries(WebAssembly and JavaScript polyfill)
      • +
    +

    Glue code

    +

    This is the code that links mCaptcha with your website’s frontend code. +It creates an iframe containing the mCaptcha widget and injects the +received verification proof token into a hidden input field.

    +

    Support is available for various frameworks, see +mCaptcha/glue for the full list.

    +

    For frameworks without official support, a low-level library, +@mcaptcha/core-glue, +can be used to implement support.

    +

    Widget Program

    +

    This part is served by the mCaptcha backend. It fetches PoW config from +the backend, generates proof and submits it for verification. If +verification is successful, it sends a message containing the +verification proof token to the parent window, assuming it’s loaded as +an iframe.

    + +

    WebAssembly library which generates Proofs of Work for mCaptcha systems.

    +

    Proof-of-Work(PoW) library

    +

    WebAssembly bindings(mCaptcha/pow_wasm) are available for the main rust library(mCaptcha/pow_sha256).

    +

    For browsers without support WebAssembly, a +polyfill(pow_sha256-polyfill) +is available.

    Pass mCaptcha challenge

    +

    The CLI tool requires details about the challenge to work on it. The +tool can be used in three different modes compute challenge:

    +
      +
    1. Protected Page: Compute mCaptcha challenge for the CAPTCHA at a +protected page
      2. +
    2. Widget URL: Compute PoW for captcha at widget URL

    3. (Developer mode) Offline: Computes PoW over given CAPTCHA parameters
      4. +
    +

    From protected page URL

    +

    The most convenient mode: copy the URL of the webpage which has the +mCaptcha widget (example: showcase.mcaptcha.org) and run the CLI tool +with it to get an authorization code: +Compute challenge using the URL

    Authorization token

    +

    When a visitor solves the CAPTCHA and sends their solution to an +mCaptcha instance, the solution will be verified for correctness. If the +solution is correct, mCaptcha will return a single use authorization token.

    +

    This authorization token should be attached to the visitor’s requited to the +protected service and the protected service should validity of the +authorization token with the mCaptcha instance and only allow authorization to +protected resource if the authorization token is valid.

    +

    Cooldown Period

    +

    mCaptcha implements leaky bucket algorithm to measure +current traffic levels. Cooldown period specifies the leak or the time +after which a visitor addition is decremented.

    +

    For instance, if initial traffic level is 0 and a user visits one +second later, the traffic level will be incremented to 1. Now, if the +cooldown period is set to 30 seconds, the traffic level will be +decremented after 30 seconds. So after 30 seconds, the traffic level will +go from 1 to 0.

    +

    Difficulty Factor

    +

    Difficulty factor determines the time it takes to solve a CAPTCHA. The +higher the difficulty factor, the longer it will take to generate a +proof of work for it to solve the CAPTCHA.

    +

    mCaptcha’s proof of work based mechanism makes it highly accessible to +people with special needs but it is important to choose the difficulty factor +with care as very high difficulty factors will make the CAPTCHA +inaccessible to users on slow devices.

    +

    Sitekey

    +

    Site key is a unique identifier associated with CAPTCHA configurations +created on mCaptcha. It is required to integrate a CAPTCHA with your +website.

    +

    Visitor Threshold

    +

    mCaptcha’s variable difficulty factor mechanism requires a website’s traffic +statistics be split into levels, so that it can deploy the right +difficulty factor for each level.

    +

    Visitor threshold is used to traffic into levels and mCaptcha accepts a +difficulty configuration for each of these levels. When current traffic +exceeds a difficulty factor, mCaptcha will increase the difficulty +factor to the next configured level.

    +

    For instance, consider the configuration given below:

    +
      +
    • Cool down period: 30 seconds
      • +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    LevelDifficulty FactorVisitor Threshold
    15,0002,000
    250,0005,000
    3500,00010,000
    45,000,00015,000
    +

    If the website sees 2,000 requests in a 30 second window, level 1 +difficulty factor(5,000) will be deployed. If the traffic increases to +5,000 requests in a 30 second window, then difficulty factor will be +upgraded to level 2(50,000). Likewise 10,000 and 15,000 requests over 30 +seconds will result in difficulty factor being upgraded to 500,000 and +5,000,000 respectively.

    +

    Visitor threshold is how mCaptcha determines which difficulty factor +level to deploy. mCaptcha uses leaky bucket algorithm to keep the +visitor threshold constantly updated within the configured cool down +period. So, at any given moment the, the current visitor level will be +the amount of traffic that was served in the cool down period specified.
