One-time pads		Still in use in some instances. Recall, one-time pads are the most secure approach
Enigma machine		Electrical lights, mechanical crank/spinwheel
AES, RSA Algorithms		I know, you wanted to think "digital" but technically, electronic works as well
Cipherdisks		Think ceasar's spin wheel here
Single photon emissions		used to provide secure key negotiation. After the test, go google "einstein spooky action" to see what will keep future CISSP's from sleeping at night

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:

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)

Question:

The ORIGINAL sender of a message encrypted using asymmetric algorithms can reverse/backout the process using the initial public key

Response:

User answer
True	Although technically, the original sender has an unencrypted version to start with, he/she cannot decrypted the message without the private key (because of the nature of asymmetric algorithms)
