Hall Of Fame
At first we wanted
to move crackmes from the old web-site, to this site, in order to have a complete,
and stable collection. But after some thought, we realized we're only interested
in the better, more interesting crackmes. So, instead of adding them to the
normal 'A-Z' archive, we've created a special place - a crackmes museum, with
the best paintings and symphonies this art of protection and de-protection has
to offer. Mind boggling crackmes, though protections, ingenious solutions and
the simple fact that great things come in small packages!
Have a look, it worth's it! :)
Btw, notice that there are no vb crackmes. Its no coincidence!
You are welcomed to recommend other crackmes that you feel should be in this
place.

One of the smallest DOS crackmes. Why is it here? Well, because is has one good point: "it's easy to make good protection even with small means." | Crook | |

Decrypting a known buffer of bytes using a given password,and than, jumping to that decrypted buffer to continue execution! There are many crackmes on these theme, and they are all though! With hard guesses and a good value of luck, there's a way out! You should also try +Spath's phi crackme and P.S.A's JMP crackme. | hijaq | |

One of the
more ingenious solutions I've seen. Way to go Merkuur! The crackme's sourcecode has also been published. |

|
Ghiri's imaginative
crackmes. As the crackers from eb's forum have discovered, caveman is actually
a game! Ipoly was one of the first crackmes that used floating point instructions. |

Do you know what's a G-LFSR? well, you should. You should also know how to reverse it. CRC32, for example, is a LFSR, and hence reversible. Have a look at Anarchriz's CRC revering article for more details. | The+Q | |

LordByte's famous crackmes. | ||

Public key
algorithms in name-code protections are becoming very common. Have a look at wizard's knapsack crackme as well. |

| rbs2 | Int13 |

Do you know what's a Feistel network? well, you should. Its a common architecture in modern symmetric ciphers. It's pretty simple to reverse, but it might appear difficult at first glance. | The+Q | |

Dongle crackme, with a beautiful solution. | Ak Kort | |

Wow! Here the protection is emulating a new, specially designed CPU. Its pretty though to trace! Have a look at anormal's intensive essay on the subject, and ghiri's CPU crackme. | ||
| Assemblur | Serge |

|
The powerful
"running line" technique. This crackmes has the most beautiful
assembly code I've ever seen! Have a look at +Aesculapius crackme for the HCU strainer, and DaFixer's solution. It features this technique under windows. |

Cracking the TEA algorithm. You might want to read Fauzan Mirza's paper on block ciphers cryptanalysis, where other attacks on the TEA algorithm are covered. | ||

A little piece of evidence can help you crack the case. | Cronos |
