ssh_server_key_api -behaviour(ssh_server_key_api).

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(6).
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()

Module:host_key(Algorithm, DaemonOptions) -> {ok, Key} | {error, Reason} Fetches the hosts private key 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 Checks if the user key is authorized 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
