Well it was quite easy form me .. I had written an RSA java applet not so long ago (with key generation, encryption and decryption). Finding D was easy because N was very small .. decrypting was easy as well ..
I double checked (even triple checked) everything but the submit score doesn't take my password .. should I do something else with the numbers I found ? please check it for me (i'll pm you)

You need to encrypt the Cyper to Chars.

Well, I see that the codes are to small to be ascii .. so I thought they can be the alphabetical index of each letter .. I got a reasonable password (of two normal english words) but the score submission doesn't take this either.

I found "p" and "q" (too easy), but I dont understand how can I get the "d"...
1 mod anything = 1
