Blowfish: cosa significa - dizionario

Un algoritmo per crittografia simmetrica (comprime e decomprime con la stessa password), gratuito e non brevettato, come dichiara l'autore. La chiave da 32 a 448 bit. Cifra dati in blocchi di 8 byte. Chiavi brevi sono state trovate, chiavi complesse apparentemente no. "Blowfish is a symmetric block cipher that can be used as a drop-in replacement for DES or IDEA. It takes a variable-length key, from 32 bits to 448 bits, making it ideal for both domestic and exportable use. Blowfish was designed in 1993 by Bruce Schneier as a fast, free alternative to existing encryption algorithms. Since then it has been analyzed considerably, and it is slowly gaining acceptance as a strong encryption algorithm. Blowfish is unpatented and license-free, and is available free for all uses. "
