Question:

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

Response:

	SCU - Security Control Unit
	ALU - Arithmetic Logic Unit
	GPU - Graphical Processing Unit
	CPU - Central Processing Unit
	Feedback: As it turns out GPU's (with their dedicated hardware of multiple ALU's) provide 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
False	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.
