ssh2_publickey_list

(PECL ssh2 >= 0.10)

List currently authorized publickeys

array ssh2_publickey_list ( resource $pkey )

List currently authorized publickeys.

Parameters:

pkey

Publickey Subsystem resource

Returns:

Returns a numerically indexed array of keys, each of which is an associative array containing: name, blob, and attrs elements.

**Publickey elements**
Array Key	Meaning
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.

Notes:

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.

Examples:

Listing authorized keys with ssh2_publickey_list()

<?php
$ssh2 = ssh2_connect('shell.example.com', 22);
ssh2_auth_password($ssh2, 'jdoe', 'secret');
$pkey = ssh2_publickey_init($ssh2);

$list = ssh2_publickey_list($pkey);

foreach($list as $key) {
  echo "Key: {$key['name']}\n";
  echo "Blob: " . chunk_split(base64_encode($key['blob']), 40, "\n") . "\n";
  echo "Comment: {$key['attrs']['comment']}\n\n";
}
?>

The above example will output:

Key: ssh-rsa
Blob: AAAAB3NzaC1yc2EAAAABIwAAAIEA5HVt6VqSGd5P
