• Both Strings key and text are in hexadecimal format where each character represents half byte and has value between 0 and F .

AES aes= new AES(text,key);

Encryption

aes.excrypt();

Returns cipher text string in hexadecimal format.

Decryption

aes.decrypt();

Returns plain text string in hexadecimal format.
