WebLos algoritmos de cifrado anteriores son probablemente AES, DES, Blowfish, CAST, IDEA, RC2, RC5, etc. Estos son algoritmos de cifrado en bloque; RC4 es un algoritmo de cifrado de flujo. Todos los algoritmos de cifrado de bloques admiten el modo de libro cifrado (ECB), el modo de enlace de bloque cifrado (CBC), el modo de …

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. See more Blowfish's use of a 64-bit block size (as opposed to e.g. AES's 128-bit block size) makes it vulnerable to birthday attacks, particularly in contexts like HTTPS. In 2016, the SWEET32 attack demonstrated how to leverage birthday attacks to perform plaintext … See more Blowfish is a fast block cipher, except when changing keys. Each new key requires the pre-processing equivalent of encrypting about 4 kilobytes of text, which is very slow compared to other block ciphers. This prevents its use in certain applications, but is … See more • Twofish • Threefish • MacGuffin See more • Bruce Schneier. "The Blowfish Encryption Algorithm". • Bruce Schneier.
