ANYONE PLEASE?

Jack wants to send Jill a secret message over email. What should he use to encrypt the message?

-Jack's public key

-Jack's private key

-Jill's public key

- Jill's private key

Jill wants to respond to Jack with a digitally signed secret message. The message is very large, and contains a video of their daughter Jane inside of it. What components are necessary for this message to be SENT correctly? (select all that apply)

-Jack's public key

-Jack's private key

-Jill's public key

- Jill's private key

-Hash of the entire message

-Hash of a private key

Rijndael can utilize all of the following key sizes except:

-128

-168

-192

-256

Whereas the decimal number system is base 10 (i.e. 0-9), Hexadecimal numbers are base 16 (i.e. 0-9 and A-F). From a computer's perspective, each hex number requires 4 bits. Given this information, what hashing algorithm could be used to output the following hash (ignore the spaces, they are merely there to help you visually)?

8F E4 61 0B 59 C7 BA A6 23 7A AE 12 43 90 1B C2 DF E1 3A F7

-MD5

-SHA-1

-SHA-256

-SHA-512

In the coming future, quantum computing will make all asymmetric algorithms obsolete.

-True or False

If you are using Elliptic curve cryptography (ECC) with 128-bit key size, this is roughly comparable security-wise to using RSA with ____ bit key size.

-128

-256

-512

-3072

A secure email system which allows for easily scaling up to hundreds, thousands, or even more individuals is:

-MIME

-PGP

-S/MIME

-GPG
