ssh2_publickey_list — List currently authorized publickeys
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.
| 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. |
Example#1 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

Note: The publickey subsystem is used for managing publickeys on a server to which the client is already authenticated. To authenticate to a remote system using publickey authentication, use the ssh2_auth_pubkey_file() function instead.
