Here we go again ... governments are trying to 'ban' encryption ... Last time it was the US govenment, this time it's the UK Government. If you are a British citizen, contact your government representive NOW and let them know that it's just insane. The link will open in a new window (bbc news article).

Input Data: (warning: be careful with newlines, browsers usually convert '\n' to '\r\n' when pasting -- work around coming soon)
Output Data:
(ONLY when using generic hash library. If you don't know, then do not check this box. HMAC At Wikipedia)
(ONLY if HMAC method is used)
(ONLY when using mcrypt, which is decryptable data. generic hashing and crypt(3) are one-way hashes)
(ONLY when using mcrypt. See wikipedia page: Block Cipher Modes)
(ONLY when using mcrypt. Please read about Block Cipher Modes for More)
(ONLY when using mcrypt, which is encryption and decryption. NOT RELEVANT with one-way hashes)
(ONLY when using crypt(3). Please read your crypt(3) manual page for more)
(ONLY when using crypt(3) with SHA-256 and SHA-512. Blank uses default of 5000. Between 1000 and 999999999)
(not relevant when using crypt(3) hashing, or when b64/uuencode/ascii85 are selected as algo)
Algorithm Name: MD2

Description: A weak algorithm invented in 1989, still used today in some public key cryptography.
