Blowfish Algorithm in Cryptography - Explore the Blowfish algorithm, a fast and secure block cipher used in cryptography. Learn its features, structure, and applications.
Key expansion and subkeys.In the key expansion process, maximum size 448-bit keys are converted into several subkey arrays, totaling 4,168 bytes. Subkeys form an integral part of the Blowfish algorithm, which uses many of them. These subkeys are precomputed before encryption or decryption can...
