|
The SSH backend generates credentials allowing clients to establish SSH
|
|
connections to remote hosts.
|
|
|
|
There are two variants of the backend, which generate different types of
|
|
credentials: One-Time Passwords (OTPs) and certificate authority. The desired behavior
|
|
is role-specific and chosen at role creation time with the 'key_type'
|
|
parameter.
|
|
|
|
Please see the backend documentation for a thorough description of both
|
|
types. The Vault team strongly recommends the OTP type.
|
|
|
|
After mounting this backend, before generating credentials, configure the
|
|
backend's lease behavior using the 'config/lease' endpoint and create roles
|
|
using the 'roles/' endpoint.
