WebThe decryption algorithm of the underlying block cipher is never used. Apparently, CFB mode is converting a block cipher into a type of stream cipher. The encryption algorithm is used as a key-stream generator to produce key-stream that is placed in the bottom register. This key stream is then XORed with the plaintext as in case of stream cipher. WebJan 9, 2024 · It is a successor of Data Encryption Standard (DES) and is stronger and faster than DES. It is a symmetric key symmetric block cipher. It operates on 128-bit (16 bytes) data. The cipher key may be of 128, 192 or 256 bits. All computations are performed on bytes rather than bits. AES gives full specification and design details.
