Question:

Which of the following components of a computer are best suited to brute force attacks?

Response:

	GPU - Graphical Processing Unit
	Feedback: Turns out GPU's have dedicate ALU's with substantially more throughput than a standalone ALU or even a multicore CPU so GPU's, given their comparative speed for encryption hacking, are the preferred hacking hardware.

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.
