As for my question, I hope it's not too hard. Here's the information:
  • The plaintext message we wish to send is M = 2
  • We'll take to very large (sarcasm, but in real implementations, they actually use large ones .. i picked them small cuz I'm doing this by hand) primes, say p = 17, q = 19
  • Let's a take a co-prime number, 35 and let it be public. So we've got e = 25
  • What is the RSA encrypted message?

If that's too obscenely difficult, here's the fallback...
  1. I'm rated at 450W
  2. My sibling is an Antec .... although really, clones we tend to be
  3. The bond between me and my Antec half-brother is a a letter and six numbers ... although I've only remembered for of them ... they are 1451
  4. I'm labeled BL for black
  5. And although the channel wall that separates yet bonds us is to evident, I cant do anything without the first part of my code...
    Whats' the code? (or even, what's the model number)

wow matey, i work in finance I havent used those top buttons on my calculator for some time.

err
p=17
q=19
n=323
e= not sure if you choose 25, or 35 coz they both < and coprime to totient (n)
m=2

let e = 25
enc(m)=m^e mod n
= 2^25 mod 323 = 223

let e = 35
= 2^35 mod 323 = 314

am i on the right lines?
Think this may be one for Yetis et al amongst us

1. It says his name
2. Grandma Smith + Myth
3. Excelled in every science
Those are the reasons that gave it away the 1st time I saw that ... and this not the 1st time I've seen that one :)

Someone else can ask a question if they so wish.

Ok this is not really a technical question but what was the first item ever sold on eBay?

lol
The first item ever sold on eBay was Omidyar's broken laser pointer for $13.83. Astonished, he contacted the winning bidder and asked if he understood that the laser pointer was broken. In his responding email, the buyer explained: "I'm a collector of broken laser pointers."
