5. An Exercise in RSA Reversal (RSA128 + MD5)

Hi and welcome to another Office Jesus tutorial. I just want to go ahead and say that if you are an ABSOLUTE beginner with no experience debugging or coding (Delphi in this case), you should NOT read this tutorial! I recommend watching Lena151's tutorials; they can be found at www.tuts4you.com. In this tutorial we will be exploring a simple serial checking routine that uses the MD5 hash and the RSA algorithm. I will not go into detail on how MD5 works or how it could be implemented. For more reading about MD5, check out the MD5 tutorials by Encrypto and ARTeam. I will try to explain RSA to the best of my ability. For further reading on RSA, visit RSA Wiki.

6. A Solution for Reverend - KeygenMe #2

This crackme is very interesting. It includes among other a virtual machine with registers from 32 bit to 128 bit, algorithm obfuscation, Taylor expansions. It is really worth having a look at it.

8. Kaos Toy Project and Algebraic Cryptanalysis

In "Toy Project" Kao presents us with a tiny, yet perverse, piece of code to reverse. Given two 32-byte strings A and B, and the 32-bit integers x and y that were used to produce B from A with the following function:
void expand(u8 B[32], const u8 A[32], u32 x, u32 y) { u32 i; for(i=0; i < 32; ++i) { out[i] = (in[i] -x) ^ y; x = ROL(x, 1); y = ROL(y, 1); } } Simple enough. How do we solve it?

14. Keygenning Encrypto KeygenMe #5

A tutorial on how to reverse a challenge from an old pal Encrypto that I have found lately and I have never reversed until now. The ultimate goal of the challenge is to code a standalone keygen and this is what I have done. The tutorial is a little bit long since it is provided with details so anyone can watch and give it a try.

If you get any kind of problems will be happy to help!

19. Keygenning Deurus KeygenMe #2

This KeygenMe is coded in Microsoft VC++ 6.0 (you can check with PeiD ) and not use of Hash Crypto's (you can check via KANAL Plugin in PeiD). In this KeygenMe we need to solve 2 algorithms so I have decided to explain all the steps to you.

20. Keygenning Phoenix-Dev Shrink

This tutorial is for the experienced reverse engineer and not a beginners help. I'm not going deep into everything, but you should be able to follow my ideas. It took me some time to understand how this protection works and I had to invent some tricks to solve it. You might have to Google some topics like RSA or modular inverse to understand the math behind it. I'm also assuming, that you know how to use the tools that I'm going to use.

I hope you learn something from this tutorial and who knows, I can get you interested in iPhone reversing.
