Public Key Encryption activity

You should form groups of 1 to 3 for this activity. If you want help finding teammates, just ask.

Your job is to compose a short message to me using my public key (82811395330715389843171661,37).

Also, make your own public key, and provide it in this forum. I'll use it to send you a message.

Your key should be at least as long as mine. You can use Mathematica's Prime function to generate two large primes to produce your n. Then use EulerPhi and, mostly, PowerMod to calculate your private key.

This part of this activity should be complete by the end of the day Monday. The table of alphabet to number conversion is (partially)

A: 00, B: 01, ..., Z: 25, ,:26, .:27, ?:28, 0:29, ..., 9:38,!:39,Space is 99. You can paste together words in one long number, but it must be smaller than the public key n in order for this to work. See the handy-dandy utility for help in making this conversion.

Have fun.
