Rc5 uses the feistel structure
WebFeistel Block Cipher - Feistel Cipher is not a specific scheme of block cipher. It is a design model from which many different block ciphers are derived. DES is just one example of a Feistel Cipher. A cryptographic system based on Feistel cipher structure uses the same algorithm for both encryption and decryption. WebAug 10, 2024 · Its structure is fiestal network. Blowfish is a symmetric block cipher that can be used as an informal replacement for DES or IDEA. It takes a variable-length key, from 32 bits to 448 bits, making it ideal for both domestic and commercial use [8]. Blowfish was designed by Bruce Schneier as a fast, free alternative to existing encryption algorithms.
