WebJun 3, 2024 · There is a fixed mapping between input blocks of plaintext and output blocks of ciphertext (essentially like an actual code book where ciphertext words directly relate to plaintext words). ECB applies the cipher function independently to each block of plaintext to encrypt it (and the inverse function to each block of ciphertext to decrypt it). WebCodes substitute arbitrary symbols—typically, letters or numbers—for the components of the original message. Ciphers use algorithms to transform a message into an apparently …
WebMay 7, 2024 · Ciphers are algorithms, more specifically they’re a set of steps for performing a cryptographic function – it can be encryption, decryption, hashing or digital signatures.
