ssh2_auth_pubkey_file — Authenticate using a public key
Description
bool ssh2_auth_pubkey_file ( resource $session , string $username , string $pubkeyfile , string $privkeyfile [, string $passphrase ] )Authenticate using a public key read from a file.
Parameters
session
An SSH connection link identifier, obtained from a call to ssh2_connect().
username pubkeyfile
The public key file needs to be in OpenSSH's format. It should look something like:
ssh-rsa AAAAB3NzaC1yc2EAAA....NX6sqSnHA8= rsa-key-20121110
privkeyfile passphrase
If privkeyfile is encrypted (which it should be), the passphrase must be provided.
Return Values
Returns TRUE on success or FALSE on failure.
Examples
Example #1 Authentication using a public key
<?php
$connection = ssh2_connect('shell.example.com', 22, array('hostkey'=>'ssh-rsa'));
if (ssh2_auth_pubkey_file($connection, 'username',
'/home/username/.ssh/id_rsa.pub',
'/home/username/.ssh/id_rsa', 'secret')) {
echo "Public Key Authentication Successful\n";
} else {
die('Public Key Authentication Failed');
}
?>Notes
Note: The underlying libssh library doesn't support partial auths very cleanly That is, if you need to supply both a public key and a password it will appear as if this function has failed. In this particular case a failure from this call may just mean that auth hasn't been completed yet. You would need to ignore this failure and continue on and call ssh2_auth_password() in order to complete authentication.
