A.A hash produces a variable output for any input size; a cipher does not. B.A cipher produces the same size output for any input size; a hash does not. C.A hash can be reversed; a cipher cannot. D.A cipher can be reversed; a hash cannot. Cipher Types - American Cryptogram Association
Explanation. The correct answer is RC4 as it is not an example of a block cipher. Because RC4 is a stream cipher. Stream Cipher is more malleable than common block ciphers. If not used together with a strong message authentication code (MAC), then stream cipher encryption is vulnerable to a bit-flipping attacks. https://en.wikipedia.org/wiki/RC4.
Encryption - Wikipedia In cryptography, encryption is the process of encoding information.  This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Only authorized parties can decipher a ciphertext back to plaintext and access the original information. Encryption does not itself prevent The question paper contains 40 multiple choice questions

How to identify the Cipher used by an HTTPS Connection Jul 18, 2020 Cryptography 101: Basic Solving Techniques for All substitution ciphers can be cracked by using the following tips: Scan through the cipher, looking for single-letter words. They’re almost definitely A or I. Count how many times each symbol appears in the puzzle. The most frequent symbol is probably E. It could also be …
