Match MySQL AES_ENCRYPT Function

See more Encryption Examples

Demonstrates how to use the MySqlAesEncrypt and MySqlAesDecrypt methods to match MySQL's AES_ENCRYPT and AES_DECRYPT functions.

Here are MySQL AES_ENCRYPT test vectors:

HEX(AES_ENCRYPT('The quick brown fox jumps over the lazy dog','password'))
Output:
CC5FDDF621AE2F48241BB80EDF2422949526FBAAA74885ACB020A74CAAB98BCFA1DD12E5D4C7922A2F9205D367921D9B

HEX(AES_ENCRYPT('The quick brown fox jumps over the lazy dog','a'))
Output:

HEX(AES_ENCRYPT('The quick brown fox jumps over the lazy dog','1234567890123456'))
Output:

HEX(AES_ENCRYPT('The quick brown fox jumps over the lazy dog','abcdefghijklmnopqrstuvwxyz'))
Output:
