You probably understand RSA, DES, AES, & ELGAMAL, so I'm wondering the purpose of the question.

With such a short message you could work this out without a calculator (somewhat tedious, but do able).

...wait a moment...!

You are looking for someone to explain elgamal... - July 9th 2009, 05:41 AMsilentbob
how would i work it out?

Hi !!

I have a cryptosystem ( supposely RSA ), such that :

p=q.

I wanted to know how i am suppose to compute phi(n) and the private key.

It's the first time that i encounter such a cryptosystem, usually p and q are relatively primes. Please help me, it's for an important assignment of mine ...
