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.

Question:

Which encryption method is most likely to be used to maintain data confidentiality on a mobile computing device (and why?)

Response:

	One-way hashing

Question:

Data stored on an encrypted file system (EFS, TrueCrypt, etc.) does not need to be encrypted when being sent over the network?

Response:

User answer
False	Protecting data-at-rest does not extend to data-in-transit. Often, encrypted data-at-rest is decrypted once it is read from the media, therefore re-encryption is needed before the data is sent over the ire (or becomes data-in-tansit)
