I wrote this code:

$host = <My Host>;
$port = 22;
$methods = array('hostkey', 'ssh-rsa');
$username = <My User>;
$pub_key = 'c:\\Users\\MyUser\\AppData\\Roaming\\ssh\\UserKeys\\pub_key.pub';
$prv_key = 'c:\\Users\\MyUser\\AppData\\Roaming\\ssh\\UserKeys\\prv_key';

print "<pre>";
var_export(file_get_contents($pub_key));
print "</pre>";
print "<pre>";
var_export(file_get_contents($prv_key));
print "</pre>";

$connection = ssh2_connect($host, 22, $methods); 
if(ssh2_auth_pubkey_file($connection, $username, $pub_key, $prv_key)){
    echo "Ok!!!!\n";
}else{
    echo "Ko!!!!";
}

When I run the code it returns:

Warning: ssh2_auth_pubkey_file(): Authentication failed for using public key: Callback returned error in....

Can anyone help me to solve this problem?

Can you login using that username and key using any SFTP/SSH client from the same machine that runs your PHP code? – Martin Prikryl Mar 01 '19 at 14:36
Yes, I can! FileZilla work good! www-data can access Public and Private key. – user9846973 Mar 01 '19 at 15:00

How does your two key files look like? Show/describe their structure + Show us FileZilla log file. + Did you try phpseclib library instead? – Martin Prikryl Mar 01 '19 at 15:26
phpseclib work fine , thanks – user9846973 Mar 01 '19 at 18:15
it is possible to work with private/public key using phpseclib? – Hugo Ferreira Dec 18 '19 at 17:04

Note, if you still can't get it working, it might be the key format, I resolved with `ssh-keygen -m PEM -t rsa` ;) – Syco Nov 02 '20 at 17:22
