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.

WebJan 1, 2024 · Blowfish's flexible key length is arguably a disadvantage, since it's an invitation to use a passphrase or other non-random secret directly as a key. This is a bad idea: block cipher key setup is supposed to be as fast as possible, while passphrases should be run through a KDF that is as slow as possible. This is only a weakness if you don't ...

Blowfish is a symmetric-key block cipher, designed in 1993 by Bruce Schneier and included in many cipher suites and encryption products. 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.
