(Delphi DLL) Match MySQL AES_ENCRYPT Function

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:
47A7E5FB591AD818BA3C9025D040514696BF50C2EFB0A453730E23E824F5F0357F3F673FCF0A7BD16465E82F937ED365

HEX(AES_ENCRYPT('The quick brown fox jumps over the lazy dog','1234567890123456'))
Output:
D70F1A158553B721C5DB9220A627E7B17BFF78FF7A72C4AB565AC903A94DF76DB75A30583D4ED01E265147D5A9B04EC3

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