Cryptage blowfish
WebBlowfish est un algorithme de chiffrement symétrique (c'est-à-dire « à clef secrète ») par blocs conçu par Bruce Schneier en 1993. Blowfish utilise une taille de bloc de 64 bits et la clé de longueur variable peut aller de 32 à 448 bits. WebBlowfish is the first symmetric encryption algorithm created by Bruce Schneier in 1993. …

WebAs I understand it, blowfish is generally seen a secure hashing algorithm, even for … WebThis makes it irreversible, essentially a hashing function. You cannot calculate the key from a cipher, even if you know the plaintext and encrypted data. Blowfish isn't better than MD5 or SHA512, as they serve different purposes. MD5 and SHA512 are hashing algorithms, Blowfish is an encryption algorithm.

Blowfish provides a good encryption rate in software, and no effective cryptanalysis of it has been found to date. However, the Advanced Encryption Standard (AES) now … See more Blowfish has a 64-bit block size and a variable key length from 32 bits up to 448 bits. It is a 16-round Feistel cipher and uses large key-dependent S-boxes. In structure it resembles CAST-128, which uses fixed S-boxes.
