copy mysql user password ? (sqlu_pass) - Eminos - 02-07-2010 12:54 AM

Hi,

I recreated/copied some databases and recreated their users on a new ispcp server. I would now like to copy the passwords from the sql_user table, but it doesn't seem to work.

If I change the password in the control panel (ispCP) it works (of course), but I would like to copy the passwords in phpmyadmin from the old sql_user to the new one on the new server.

If I set THE SAME password via ispCP control panel, it doesn't generate the same output in the sql_user table on the old and the new server.

Could someone explain?
Why doesn't this seem to work?

Thanks in advance..

Oh yes, and the old ispCP is 1.0.0 and the new one is 1.0.3-1.
Has the sqlu_pass crypt hash changed ?

No, what's different is the encryption key used by your servers. These keys are generated during the installation, so to export passwords from one server to another you have to either:

- Decrypt the passwords first (using the key from "server1") and re-encrypt them afterwards (using the key from "server2")
- Use the same encryption keys on both servers.

Extra hint: the encryption keys are stored in the following three files:
Code:
/var/www/ispcp/engine/messager/ispcp-db-keys.pl
/var/www/ispcp/engine/ispcp-db-keys.pl
/var/www/ispcp/gui/include/ispcp-db-keys.php

Great answer. Thanks.

Because I have already created some new sites the complete use of the old encryption keys is not possible (I would break the new passwords).

How can I de-crypt with old encryption keys and re-encrypt with new ones? I have access to both the old and the new ispCP server.

Thanks in advance.

You can do it with the following functions (php):
Code:
function decrypt_db_password ($db_pass, $ispcp_db_pass_key, $ispcp_db_pass_iv) {
        if ($db_pass == '')
                return '';

        if (extension_loaded('mcrypt') || @dl('mcrypt.' . PHP_SHLIB_SUFFIX)) {
                $text = @base64_decode($db_pass . "\n");
                // Open the cipher
                $td = @mcrypt_module_open ('blowfish', '', 'cbc', '');
                // Create key
                $key = $ispcp_db_pass_key;
                // Create the IV and determine the keysize length
                $iv = $ispcp_db_pass_iv;

                // Intialize encryption
                @mcrypt_generic_init ($td, $key, $iv);
                // Decrypt encrypted string
                $decrypted = @mdecrypt_generic ($td, $text);
                @mcrypt_module_close ($td);

                // Show string
                return trim($decrypted);
        } else {
                die();
        }
}

function encrypt_db_password($db_pass, $ispcp_db_pass_key, $ispcp_db_pass_iv){
        if (extension_loaded('mcrypt') || @dl('mcrypt.' . PHP_SHLIB_SUFFIX)) {
                $td = @mcrypt_module_open (MCRYPT_BLOWFISH, '', 'cbc', '');
                // Create key
                $key = $ispcp_db_pass_key;
                // Create the IV and determine the keysize length
                $iv = $ispcp_db_pass_iv;

                //compatibility with used perl pads
                $block_size=@mcrypt_enc_get_block_size($td);
                $strlen=strlen($db_pass);

                $pads=$block_size-$strlen % $block_size;

                for ($i=0; $i<$pads;$i++){
                        $db_pass.=" ";
                }
                // Intialize encryption
                @mcrypt_generic_init ($td, $key, $iv);
                //Encrypt string
                $encrypted = @mcrypt_generic ($td, $db_pass);
                @mcrypt_generic_deinit($td);
                @mcrypt_module_close($td);

                $text = @base64_encode("$encrypted");
                $text=trim($text);
                return $text;
        } else {
                die("ERROR: The php-extension 'mcrypt' not loaded!");
        }
}
