ssh_client_key_api(3)

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(6) application manual.

DATA TYPES

Type definitions that are used more than once in this module, or abstractions to indicate the intended use of the data type, or both. For more details on public key data types, refer to Section 2 Public Key Records in the public_key user's guide:

    boolean() =:
        true | false

    string() =:
        [byte()]

    public_key() =:
        #'RSAPublicKey'{} | {integer(),#'Dss-Parms'{}} | {#'ECPoint'{},{namedCurve,Curve::string()}}

    private_key() =:
        #'RSAPrivateKey'{} | #'DSAPrivateKey'{} | #'ECPrivateKey'{}

    public_key_algorithm() =:
        'ssh-rsa' | 'ssh-dss' | 'rsa-sha2-256' | 'rsa-sha2-384' | 'rsa-sha2-512' | 'ecdsa-sha2-nistp256' | 'ecdsa-sha2-nistp384' | 'ecdsa-sha2-nistp521'

EXPORTS

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

    Types:
        HostNames = string()
            Description of the host that owns the PublicKey.
        Key = public_key()
            Normally an RSA, DSA or ECDSA public key, but handling of other public keys can be added.
        ConnectOptions = proplists:proplist()
            Options provided to ssh:connect/[3,4]. The option list given in the key_cb option is available with the key key_cb_private.
        Reason = term().

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

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

    Types:
        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 = public_key_algorithm()
            Host key algorithm.
        ConnectOptions = proplists:proplist()
            Options provided to ssh:connect/[3,4]. The option list given in the key_cb option is available with the key key_cb_private.
        Result = boolean()

    Checks if a host key is trusted.

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

    Types:
        Algorithm = public_key_algorithm()
            Host key algorithm.
        ConnectOptions = proplists:proplist()
            Options provided to ssh:connect/[3,4]. The option list given in the key_cb option is available with the key key_cb_private.
        PrivateKey = 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.
