List currently authorized publickeys.
Publickey Subsystem resource
Returns a numerically indexed array of keys, each of which is an associative array containing: name, blob, and attrs elements.
|name||Name of algorithm used by this publickey, for example: ssh-dss or ssh-rsa.|
|blob||Publickey blob as raw binary data.|
|attrs||Attributes assigned to this publickey. The most common attribute, and the only one supported by publickey version 1 servers, is comment, which may be any freeform string.|
The public key subsystem is used for managing public keys on a server to which the client is already authenticated. To authenticate to a remote system using public key authentication, use the ssh2_auth_pubkey_file function instead.
