WebIn cryptography, ciphertext feedback (CFB), also known as cipher feedback, is a mode of operation for a block cipher. Ciphertext refers to encrypted text transferred from plaintext … WebThe key is exactly same as the length of message which is encrypted. The key is made up of random symbols. As the name suggests, key is used one time only and never used again for any other message to be encrypted. Due to this, encrypted message will be vulnerable to attack for a cryptanalyst.
