NAME

       ssh_server_key_api -
           -behaviour(ssh_server_key_api).

DESCRIPTION

       Behaviour  describing  the  API  for  an  SSH server's public key handling. By implementing the callbacks
       defined in this behavior it is possible to customize the SSH server's public key handling. By default the
       SSH application implements this behavior with help of the standard openssh files, see  ssh(7).

DATA TYPES

       Type definitions that are used more than once in this module and/or abstractions to indicate the intended
       use of the data type. For more details on public key data types see the  public_key user's guide.

       boolean() = true | false

       string() = [byte()]

       public_key() = #'RSAPublicKey'{} | {integer(), #'Dss-Parms'{}} | term()

       private_key() = #'RSAPrivateKey'{} | #'DSAPrivateKey'{} | term()

       public_key_algorithm() = 'ssh-rsa' | 'ssh-dss' | atom()

EXPORTS

       Module:host_key(Algorithm, DaemonOptions) -> {ok, Key} | {error, Reason}

              Types:

                 Algorithm = public_key_algorithm()
                    Host key algorithm. Should support 'ssh-rsa' | 'ssh-dss' but additional  algorithms  can  be
                   handled.
                  DaemonOptions = proplists:proplist()
                   Options provided to ssh:daemon/[2,3]
                  Key = private_key()
                    The private key of the host matching the Algorithm
                 Reason = term()

              Fetches the hosts private key

       Module:is_auth_key(Key, User, DaemonOptions) -> Result

              Types:

                  Key = public_key()
                    Normally an RSA or DSA public key but handling of other public keys can be added
                  User = string()
                    The user owning the public key
                  DaemonOptions = proplists:proplist()
                    Options provided to ssh:daemon/[2,3]
                  Result = boolean()

              Checks if the user key is authorized
