WebBlowfish is a symmetric block cipher. It uses a variable-length key ranging from 32 to 448 bits. Blowfish was designed in 1993 by Bruce Schneier. It has been analyzed extensively by the cryptography community and has gained wide acceptance. It is also a noncommercial (free of charge) product, thus making it attractive to budget-conscious ... Cryptographic hash functions are cryptographic algorithms that generate and use keys to encrypt data, and such functions may be viewed as keys themselves. They take a message of any length as input, and output a short, fixed-length hash , which can be used in (for example) a digital signature.
