Module

ssh_client_key_api

Module Summary

-behaviour(ssh_client_key_api).

Since

Module ssh_client_key_api was introduced in OTP R16B.

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

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}
 OTP R16B

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
 OTP R16B

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}
 OTP R16B

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.
