It takes in an email and plain text password to verify. If it fails to find a password stored for email, it returns not_found. If it finds the password hash stored but that hash doesn't match the password passed via the API, it returns verified = false, else it returns verified = true.

# Running a Dex gRPC client
|
|
|
|
Using gRPC, a client application can directly call methods on a server application as if it was a local object. The schema for Dex's gRPC API calls is defined in [`api/api.proto`][api-proto]. [`client.go`][client] is an example client program that makes a bunch of API calls to the dex server. For further details on the Dex API refer [`Documentation/api.md`][api-docs].
|
|
|
|
## Generating Credentials
|
|
|
|
Before running the client or the server, TLS credentials have to be setup for secure communication. Run the `cred-gen` script to create TLS credentials for running this example. This script generates a `ca.crt`, `server.crt`, `server.key`, `client.crt`, and `client.key`.
|
|
|
|
```
|
|
# Used to set certificate subject alt names.
|
|
export SAN=IP.1:127.0.0.1
|
|
|
|
# Run the script
|
|
./examples/grpc-client/cert-gen
|
|
```
|
|
To verify that the server and client certificates were signed by the CA, run the following commands:
|
|
|
|
```
|
|
openssl verify -CAfile ca.crt server.crt
|
|
openssl verify -CAfile ca.crt client.crt
|
|
```
|
|
|
|
## Running the Dex server
|
|
|
|
To expose the gRPC service, the gRPC option must be enabled via the dex config file as shown below.
|
|
|
|
```yaml
|
|
# Enables the gRPC API.
|
|
grpc:
|
|
addr: 127.0.0.1:5557
|
|
tlsCert: server.crt
|
|
tlsKey: server.key
|
|
|
|
```
|
|
Start an instance of the dex server with an in-memory data store:
|
|
|
|
```
|
|
./bin/dex serve examples/grpc-client/config.yaml
|
|
```
|
|
|
|
## Running the Dex client
|
|
|
|
Finally run the Dex client providing the CA certificate, client certificate and client key as arguments.
|
|
|
|
```
|
|
./bin/grpc-client -ca-crt=ca.crt -client-crt=client.crt -client-key=client.key
|
|
```
|
|
Running the gRPC client will cause the following API calls to be made to the server
|
|
1. CreatePassword
|
|
2. ListPasswords
|
|
3. VerifyPassword
|
|
4. DeletePassword
|
|
|
|
## Cleaning up
|
|
|
|
Run the following command to destroy all the credentials files that were created by the `cert-gen` script:
|
|
|
|
```
|
|
./examples/grpc-client/cert-destroy
|
|
```
