Here is source of AES encryption algorithm written in C#

How to use this class

- string plainText - string you want encrypt
- chiperText - string you want decrypt
- passPharse - what ever password you want
- saltValue - can be any string, act like secon password
- hashAlgorithm - can be SHA1, MD5, SHA512 etc...
- passwordIterations - any number
- initVector - must be "@1B2c3D4e5F6g7H8";
- keySize - can be 128,192,256
