I have now managed to write my decyption program and have found the original message in Realistic 6.
Problem is I have no idea how to "reply" and return the message :(


Glad I could help.
Go check the Realistic 6 forum, I'm sure you're not the first person who had that problem.
They call me Ishmael... I'm not sure why.

wish i had seen this first.............. i brute forced it, a password that small isn't so bad, especially when you've figured out the pattern and tested it a bit, i enjoy puzzles like it........... makes the brain work for once............. (teachers are worthless, so very little in a public school is of interest, or the teachers kill it themselves)

You pick a specific language to write the program with, then you use the commands specific to that language that carries out the actions necessary to encrypt / decrypt the way your code does.

--------
Ontopic:
I expected more than just 1 way of ''encryption'' for something called "Cryptography 101".
Perhaps add a few other methods as well? Playfair Cipher etc. (As they are different, shows people the different way some things work.)

Perfect explanation for XE though.

Oh, but is the most frequent number always the one in which we have to subtract 32? Also, is it always the number 32 that we subtract from the most frequent number?

Edit: nvm, no need to answer this question anymore

Hey man, want to say thanks for the tutorial - helped me loads.

I managed to use the tutorial to code myself a program which is currently decrypting Realistic 6.

Thanks again :)

Nobody has posted here in over a year. Let it die. I doubt he's even here still.
Assume that everything I say is or could be a lie.
