NAME

       ssh_client_key_api -
            -behaviour(ssh_client_key_api).

DESCRIPTION

       Behavior  describing  the  API  for  public  key handling of an SSH client. By implementing the callbacks
       defined in this behavior, the public key handling of an SSH client can be customized. By default the  ssh
       application implements this behavior with help of the standard OpenSSH files, see the  ssh(7) application
       manual.

DATA TYPES

       client_key_cb_options() =
           [{key_cb_private, term()} | ssh:client_option()]

              Options provided to ssh:connect/[3,4].

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

EXPORTS

       Module:add_host_key(HostNames, PublicHostKey, ConnectOptions) -> ok | {error, Reason}

              Types:

                 HostNames = string()
                   Description of the host that owns the PublicHostKey.
                 PublicHostKey = public_key:public_key()
                   Of ECDSA keys, only the Normally an RSA, DSA or ECDSA  public  key,  but  handling  of  other
                   public keys can be added.
                 ConnectOptions = client_key_cb_options()

              Adds a host key to the set of trusted host keys.

       Module:is_host_key(Key, Host, Algorithm, ConnectOptions) -> Result

              Types:

                 Key = public_key:public_key()
                   Normally an RSA, DSA or ECDSA public key, but handling of other public keys can be added.
                 Host = string()
                   Description of the host.
                 Algorithm = ssh:pubkey_alg()
                   Host key algorithm.
                 ConnectOptions = client_key_cb_options()
                 Result = boolean()

              Checks if a host key is trusted.

       Module:user_key(Algorithm, ConnectOptions) -> {ok, PrivateKey} | {error, Reason}

              Types:

                 Algorithm = ssh:pubkey_alg()
                   Host key algorithm.
                 ConnectOptions = client_key_cb_options()
                 PrivateKey = public_key:private_key()
                   Private key of the user matching the Algorithm.
                 Reason = term()

              Fetches the users public key matching the Algorithm.

          Note:
              The private key contains the public key.
