ElGamal Example
p is a prime, g is a primitive root of p, a is a random secret number (must be less than p).
p = 2789; g = 10; a = 304
g^a % p = 10^304 (% 2789) ≡ 1161
Now we have what is known as a 'public key' (p, g, g^a%p).
The public key is P = (p ← 2789, g ← 10, g^a%p ← 1161), the secret key is a (304).
Next, we encrypt a message m = 832 as follows (k is randomly chosen, m has to be less than p):
k = 1520
γ = 10^1520 (% 2789) ≡ 2300
δ ≡ 832 x 1161^1520 (% 2789) ≡ 83
c = (γ ← 2300, δ ← 83)
The ciphertext, c, is then sent to the recipient.
The recipient can then calculate m from this. The message is calculated by:
m ≡ 2300^(2789-1-304) x 83 ≡ (2300^2484) x 83 (% 2789) ≡ 832
When looking for 6 digit numbers, it will either be the public key, the cipher text or, possibly, p.
Possible primes, p > 304, with a prime root of 10:
313, 337, 367, 379, 383, 389, 419, 433, 461, 487, 491, 499, 503, 509, 541, 571, 577 ...

IOn the Nokia Conversations blog, I read some Nokia guy (Ray SomethingOrOther) suggesting that Nokia had 'delivered' on their promise of releasing the first Meego device in 2011. Obviously the term 'delivered' in NokiaSpeak means getting it in the hands of Nokia management, rather that paying customers. For some reason I pictured this guy stood on an aircraft carrier in front of big sign saying 'Mission Accomplished'.

What's funny and sad(for nokia fans) is that had this contest been posted for the iPhone users, it would've been solved in one hour, all 20 questions.
But nokia simply does not have enough people to bother solving their nonsense, it's basically this forum and mynokiablog. That's like 15 people bothering with this.
