mysql database encryption

<?php
$Key = md5('MasnadIsAwesome');

//Encrypt
function encrypt($String, $Key){
	$string = rtrim(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $Key, $String, MCRYPT_MODE_ECB)));
	return $string
}

// Decrypt

function decrypt($String, $key){
	$string = rtrim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $Key, base64_decode($String), MCRYPT_MODE_ECB));
	return $string;
}

// Change all mysql table to varbinary where the encrption is necessary

### Example of insert statement with encrypt ####
$sql = "INSERT INTO user (name, address) VALUES ('".encrypt($name, $Key)."' , '".encrypt($address, $Key)."')" ;

// Decrypt is easier and it can be done in the function
decrypt('stuff', $Key);
