Cryptographically strong Correct Answer: C The ROT13 cipher exchanges each letter of a message for the letter that is 13 places ahead of it in the alphabet. This is an example of a substitution operation. Transposition ciphers rearrange the letters in a message, which is not occurring here. ROT13 is quite weak and would never be considered cryptographically strong. It also does not perform hashing of messages into message digests. Interested in more practice test questions?
