To encrypt & decrypt mysql data we will use AES_ENCRYPT() and AES_DECRYPT() functions. These functions used the official AES (Advanced Encryption Standard) algorithm & encode data with a 128-bit key length. 128 bits is much faster and secure enough for most purposes.

Because AES_ENCRYPT() encrypts a string and returns a binary string. AES_DECRYPT() decrypts the encrypted string and returns the original string.

AES is a block-level algorithm. So when data encrypted it is padded. So you can calculate the length of the result string using this formula:

1.) 16 × (trunc(string_length / 16) + 1)

So if your address field structure is = VARCHAR(100) ; //100 length of varchar Then before your encryption it should be converted

= 16 * (trunc(100/ 16) + 1) = 16 * (6.25 + 1) = 16 * 7.25 = 116 

So VARCHAR(100) should be converted to VARBINARY(116) minimum. I suggest use little more like VARBINARY(150) in this case.

Because if AES_DECRYPT() detects invalid data or incorrect padding, it will return NULL. But it is also possible for AES_DECRYPT() to return a non-NULL value (possibly garbage) if the input data or the key is invalid.

Syntax:

1.) AES_ENCRYPT(str, key_str);

 

2.) AES_DECRYPT(crypt_str,key_str);

Please remember, the encryption and decryption will occur based on a key. So you’ve to keep that key in a secret place and using variable you could pass the key to mysql to encrypt and decrypt data.

AES_ENCRYPT() and AES_DECRYPT() can be considered the most cryptographically secure encryption functions currently available in MySQL.

Inserting data as follows:

INSERT into user (first_name, address) VALUES (AES_ENCRYPT('Obama', 'usa2010'),AES_ENCRYPT('Obama', 'usa2010')); 

Retrieving data as follows:

SELECT AES_DECRYPT(first_name, 'usa2010'), AES_DECRYPT(address, 'usa2010') from user; 

additional notations:

You'll need to apply a salt to the data that you encrypt. This is a special code that the encryption algorithm uses which works a bit like a key.

You'll need to provide the exact same key back to decrypt the data, and if an attacker should gain access to your database, they won't be able to decipher it without knowing the salt.

If you define your salt in PHP like this, you'll be able to pull the constant into your SQL statements more easily.
