ssh_server_key_api -behaviour(ssh_server_key_api).

Behaviour describing the API for public key handling of an SSH server. By implementing the callbacks defined in this behavior, the public key handling of an SSH server can be customized. By default the SSH application implements this behavior with help of the standard OpenSSH files, see the ssh(6) application manual.

Options provided to ssh:daemon/2,3.

The option list given in the key_cb option is available with the key key_cb_private.

Module:host_key(Algorithm, DaemonOptions) -> {ok, Key} | {error, Reason} Fetches the host’s private key. Algorithm = ssh:pubkey_alg() Host key algorithm. DaemonOptions = daemon_key_cb_options() PrivateKey = public_key:private_key() | crypto:engine_key_ref() Private key of the host matching the Algorithm. It may be a reference to a 'ssh-rsa', rsa-sha2-* or 'ssh-dss' (NOT ecdsa) key stored in a loaded Engine. Reason = term()

Fetches the private key of the host.

 Module:is_auth_key(PublicUserKey, User, DaemonOptions) -> Result Checks if the user key is authorized. PublicUserKey = public_key:public_key() Normally an RSA, DSA or ECDSA public key, but handling of other public keys can be added User = string() User owning the public key. DaemonOptions = daemon_key_cb_options() Result = boolean()

Checks if the user key is authorized.
