From Citizendium < Blowfish (cipher) Jump to: navigation, search. [9] The GnuPG project recommends that Blowfish not be used to encrypt files larger than 4 GB[10] due to its small block size. Blowfish { proper } Blowfish (cipher) Jag höll på att komma med i Hootie the Blowfish! The algorithm is hereby placed in the public domain, and can be freely used by anyone."[3]. And given the slow initialization of the cipher with each change of key, it is granted a natural protection against brute-force attacks, which doesn't really justify key sizes longer than 448 bits. It uses the block cipher method, which breaks the text into 64-bit blocks before encrypting them. Blowfish has a good encryption rate in software and until 2008 no cryptanalytic attack model of it has been found. Blowfish is a fast block cipher, except when changing keys.
