Signatures

Each of us must set up an RSA signature. Publish your own RSA information. Then send your RSA signature to this web page. Please use a few letters for your signature which indicates who you are.

Each of us must do the same for the El Gamal signed message. Choose a brief message and the same letters for your signature, send it to this web site.

Each person should take the time to verify my signatures below and each person should hack my RSA encrypted message.

Here's an RSA signature for you to verify. PQ = 72894286763, e = 3553. Signature: snot, 11211284034 11211284034^e (mod PQ) gave me back the numbers that correspond to 'snot', so it works. user:meganternes Likewise user:Ian.hart Me too! user:kml003 I did too user:bea001

Here's an ElGamal message with signature. The message has been encrypted with RSA using PQ = 60120185889229169423, e = 1152415. You'll have to hack the message to find out what it says. m = 45047235519679159684

**In response to your message: wow, even I get one? user:bea001**

The ElGamal public information is P = 115241558585000900207 alpha = 5 beta = 106576684373546478239.

My message, signature is (45047235519679159684, r=103018961071910370889 s= 86004434925837099090). For the ElGamal, both v1 and v2 came out the same, which they should. user:meganternes Mine calculations agree too. user:kml003

Go and do likewise. Please do not post the decrypted message. Keep it to yourself so everyone has a chance to crack it.

__RSA__ PQ = 40789139819, e = 1321 signature: (read, 9339258132)

__ElGamal__ I used RSA to encrypt my message. PQ = 123728620277, e = 133 so now m = 82015251211

Public ElGamal info: P = 6872684551 alpha = 21 beta = 1062803423
