ssh2_auth_pubkey_file
SSH2_AUTH_PUBKEY_FILE(3) 1 SSH2_AUTH_PUBKEY_FILE(3)ssh2_auth_pubkey_file - Authenticate using a public keySYNOPSIS
bool ssh2_auth_pubkey_file (resource $session, string $username, string $pubkeyfile, string $privkeyfile, [string $passphrase])
DESCRIPTION
Authenticate using a public key read from a file.
PARAMETERS
o $session
- An SSH connection link identifier, obtained from a call to ssh2_connect(3).
o $username
-
o $pubkeyfile
- The public key file needs to be in OpenSSH's format. It should look something like: ssh-rsa AAAAB3NzaC1yc2EAAA....NX6sqSnHA8=
rsa-key-20121110
o $privkeyfile
-
o $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
";
} 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(3) in order to complete
authentication.
