Question:
A SHA-256 system will always generate different hashes when given the same plaintext, no matter how many times it is invoked
-
Response:
User answer | |
True | A hash is a hash is a hash, it never changes the output. Hashes are used to prove integrity, usually by comparing current hashes (aka message digests) against previous ones (stored filesystems checksums, for example) to prove nothing has changed. Therefore, a hashing algorithm must produce one and only one output per plaintext input.
