# Pluggable function changing password encryption

 * I have created a simple plugin (yes, it is activated). The plugin contains:
 *     ```
       <?php
           /**
            * Plugin Name: Password Encryption
            * Description: Password Encryption
            */
   
           if ( !function_exists('wp_set_password') ){
           	function wp_set_password( $password, $user_id ) {
           		global $wpdb;
           		$enc = mcrypt_encrypt(MCRYPT_RIJNDAEL_128,'ABC',$password,MCRYPT_MODE_CBC,'XYZ');
           		$r = base64_encode($enc);
           		$wpdb->update($wpdb->users, array('user_pass' => $r, 'user_activation_key' => ''), array('ID' => $user_id) );
           		wp_cache_delete($user_id, 'users');
           	}
           }
   
           if ( !function_exists('wp_check_password') ){
           	function wp_check_password($password, $hash, $user_id = '') {
           		if ( $user_id ) {
           			wp_set_password($password, $user_id);
           			//$hash = wp_hash_password($password);
           			$hash = '';
           			$r = base64_decode($password);
           			$hash = mcrypt_decrypt(MCRYPT_RIJNDAEL_128,'ABC',$r,MCRYPT_MODE_CBC,'XYZ');
           		}
           		return apply_filters( 'check_password', false, $password, $hash, $user_id );
           	}
           }
       ```
   
 * My problem is my plugin has no effect on the password encryption, these 2 functions
   are in the wp-includes/pluggable.php, so I thought this would overwrite them.
   Am I missing something? Is there a better or easier way to do this?
 * Thanks.

 * I figured it out. I needed to change the wp_check_password and wp_hash_password
   functions. Here is my solution.
 *     ```
       <?php
       /**
        * Plugin Name: Password Encryption
        * Description: Password Encryption
        */
   
       if ( !function_exists('wp_hash_password') ){
   
       	function wp_hash_password($password) {
       		$enc = mcrypt_encrypt(MCRYPT_RIJNDAEL_128,'ABC',$password,MCRYPT_MODE_CBC,'XYZ');
       		$r = base64_encode($enc);
       		return trim($r);
       	}
       }
   
       if ( !function_exists('wp_check_password') ){
       	function wp_check_password($password, $hash, $user_id = '') {
       		global $wp_hasher;
       		$check = false;
       		if ( $user_id ) {
       			$test = wp_hash_password($password);
       		}
       		if($test == $hash ){
       			$check = true;
       		}
       		return apply_filters( 'check_password', $check, $password, $hash, $user_id );
       	}
       }
   
       ?>
       ```
   
 * Super easy to change the encryption once I really read through the WordPress 
   functions.
