# Restrict allowed SSH key technologies and minimum length
|
|
|
|
`ssh-keygen` allows users to create RSA keys with as few as 768 bits, which
|
|
falls well below recommendations from certain standards groups (such as the US
|
|
NIST). Some organizations deploying GitLab will need to enforce minimum key
|
|
strength, either to satisfy internal security policy or for regulatory
|
|
compliance.
|
|
|
|
Similarly, certain standards groups recommend using RSA, ECDSA, or ED25519 over
|
|
the older DSA, and administrators may need to limit the allowed SSH key
|
|
algorithms.
|
|
|
|
GitLab allows you to restrict the allowed SSH key technology as well as specify
|
|
the minimum key length for each technology.

In the Admin area under **Settings** (`/admin/application_settings`), look for
|
|
the "Visibility and Access Controls" area:
