ARCFour - stream cipher

This is a JavaScript implementation of the ARCFour stream cipher ("alleged RC4"). Below, you can test both encryption and decryption. If some tests fail, please report to me your browser version (both vendor and version number as well as your OS) and the corresponding error message: chris 'at' bichlmeier 'dot' info

Note:If you want to decrypt data, you have to input a hex string containing the encrypted data. The generated key is 16 bytes long and isn't random enough to meet the requirements of crypto applications.
