Found the encryption and decryption things are pretty helpful.
i.e. in generating CAPTCHA images, using encrypted values
on the query string is quite necessary...
What are the (en|de)crypting methods you ppl are using? or what
other kinds of tech I can use to handle this.....

AES128 or AES256 for encryption and decryption
HMAC-SHA1 for signing
