Blowfish (cipher)
In cryptography, Blowfish is a keyed, symmetric block cipher, made in 1993 by Bruce Schneier and since 1993 has been included(put together) in a large number of encryption products. Blowfish has a good encryption rate in software and until 2008 no cryptanalytic attack model of it has been found. However, the AES block cipher algorithm now has more attention.
