Hi,

I had a problem with secure connection to sql server.

I use mysqli extension, I configured server['ssl'] = true. I have a user 'szabolcs' in sql who needs ssl.

First I received 'mysqli_real_connect(): (HY000/1045): Access denied for user 'szabolcs'@'localhost' (using password: YES)'.

That was why PMA doesn't use MYSQLI_CLIENT_SSL. I should add it to $client_flags.

After this I got the following error:'mysqli_query(): SSL operation failed with code 1. OpenSSL Error messages: error:0607A082:digital envelope routines:EVP_CIPHER_CTX_set_key_length:invalid key length error:0607A082:digital envelope routines:EVP_CIPHER_CTX_set_key_length:invalid key length'.

PMA uses openssel functions to encrypt values in cookie if openssl functions exist, other case PMA uses Crypt\AES. With Crypt\AES PMA works fine.

I don't know the exact source of this problem. I think openssl functions have a bug.

Because the mysqli connection with ssl is successful  After connection in common.inc.php $auth_plugin->storeUserCredentials() is called. This function stores the username and password and other parameters into cookie. To encrypt:

openssl_encrypt(

                $data,

                'AES-128-CBC',

                $secret,

                0,

                $this->_cookie_iv

            );

I think the problem is that openssl_encrypt change the cipher to AES-128-CBC globally. It means the cipher of mysqli connection is also modified. This is why mysqli_query failed after encryption.

Here is my solution:
