Explanation:
Detailed explanation-1: -5) Which of the following modes of operations can be followed for both stream ciphers as well as block ciphers? Explanation: CFB is primarily a mode to derive some characteristics of a stream cipher from a block cipher on the cryptography in cryptoanalysis.
Detailed explanation-2: -Introduction to Block Cipher modes Where ECB and CBC mode works on block ciphers, and CFB and OFB mode works on block ciphers acting as stream ciphers.
Detailed explanation-3: -Block cipher and stream cipher are members of the family of symmetric key ciphers, essentially encryption techniques used for directly transforming the plaintext into ciphertext.
