ok, here is a small very very small hint. the sentance length encrypted is exactly the same as the sentance length decrypted.
 
Well I've got the message decrypted, just gotta figure out your decryption scheme now 🙂

edit: err, make that encryption scheme 😕
 
i think there are couple common encryption methods out there:

the caesar method C = P + k (mod 26), where C is the encrypted text, P is the original text, k is an integer that u add to P
a better caesar method : C = aP + k (mod 26)
exponential method: C = P^e (mod p) where p is some prime, and e is a number that is relatively prime to p
RSA method (best one so far): C = P^e (mod n), where n is some composite that can be factored into big primes, e is an integer that is relatively prime to phi(n) (which is the Euler function of n)

 
i bet it has something to do with the keyboard and shifting evrything over one letter on the qwerty board or something dumb.
 
Decrypt this message and you are a winner. Tell us how it's encrypted and you when twice! good luck

I guessed on the 42nd and 89th characters (counting spaces).

And I have no clue what scheme was used to encrypt it...
 
Well, certainly not the most orginal message. You should have put wInnAr!! or at least a matrix transformation encryption. From the looks of it, I'm guessing it's probably mod the ASCI value with a number.

I agree RSA is great algorithm for Public-Key Encryption but it's not really the best encyrption algorithm out there.

The amount of work required to crack an RSA key of a given length is much less than the amount of work required to crack a symmetric key, such as 3DES or AES, of the same length.

It's a lot easier to try and factor n than it is to use brute-force through the entire key space.



Edit: Of course both have their advantages over the other.

Symmetric encyption algorithms like 3DES & AES are much faster than RSA but RSA doesn't have as big of problem with key-distribution.

If you liked this thread you might like "The Code Book" by Simon Singh. It's a great little read and spawned an interest in cryptography for me.
