448Delta Encryption Algorithm

448Delta Uses A Highly Modified 448-Bit BlowFish Algorithm

Blowfish is a block cipher encryption algorithm that encrypts data in 8-byte blocks. The algorithm consists of two parts: A key-expansion part and a data-encryption part.

Key expansion converts a variable-length key of at most 56 bytes (448 bits) into several subkey arrays totaling 4168 bytes.

Blowfish has 16 rounds. Each round consists of a key-dependent permutation, a key and data-dependent substitution. All operations are XORs and additions on 32-bit words. The only additional operations are four indexed array data lookups per round.

No one has come close to developing an attack that breaks Blowfish.
