transfer encrypted mailpass from RC7 to 1.0 on another server - Catscrash - 03-06-2009 11:15 PM

Hi,
i'm moving from a server with RC7 (which has already encrypted emailpasswords for users) to a server with 1.0

I created the old mailboxes on the new server with a temporary password and tried then to copy the old encrypted passwords from ispcp.mail_users

Did the encryption change? Cause that doesn't work...

I can't Email a lot of users and say them, sry folks i just changed all ur passwords to "xyz" ;-)

Thanks for every help

Encryption depends on keys from ispcp-db-keys.* You need to decrypt password on old server, then reencrypt with keys from the new server. then it will work Wink

thx!

$db_pass is the encrypted/unencrypted password, and the other values can be found on the /var/www/ispcp/gui/include/ispcp-db-keys.php file of the corresponding server.

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 {

                system_message("ERROR: The php-extension 'mcrypt' not loaded!");

                die();

        }

}

Code:

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 {

                //system_message("ERROR: The php-extension 'mcrypt' not loaded!");

                die("ERROR: The php-extension 'mcrypt' not loaded!");

        }
