WebIn cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption —a series of well-defined steps that can be followed as a procedure. An alternative, less … WebAES-256 is a kind of block cipher. It takes as input a 32-byte key and a 16-byte string, called the block and outputs a block. We use AES in a mode of operation in order to encrypt. The solutions above suggest using CBC, which is one example. Another is called CTR, and it's somewhat easier to use:

WebApr 25, 2016 · First RC4 is not a block cipher, is a stream cipher. Second, the decryption is exact the same as the encryption, as the algorithm generates the ciphertext by XORing the plaintext with some stream obtained using the key, and XOR is reversible, meaning: to decypher just need to XOR the ciphertext with the same generated stream.
