Did we help you? Help us, and share the word to your geek friends!

Hey, what about crypto? Did crypto itself help you? Did you know that the US government and other various government organizations are trying to do really harmful things to cryptography as a whole? The least you could do is sign a petition to save cryptography. It will open a new new window, and when you're done you can come back here to get back to work.

NEW: Get your IP in plain text, and Random password & data - VERY NEW: Unix Timestamp Converter (2-way)

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: CRC32 (b)

Description: CRC32 is a common algorithm for computing checksums to protect against accidental corruption and changes.
