To run it on systems other than NixOS, you have to patch the file to set a valid interpreter-path. First, find your ld-linux-x64-64.so.2.
On my system it is:
patchelf --set-interpreter /usr/lib/ld-linux-x86-64.so.2 target_bin

If you run this in a VM and get error "CPU ISA level is lower than required" then run this in terminal:
objcopy --remove-section .note.gnu.property crackme

Ehmm. Password in plain text...
Your encryption function looks interesting, but is useless because of that. |

Valid key (there are many valid keys):

DLLs can be found in MinGW/bin.
The solution is way too easy. This should be difficulty 1.0 |

Missing DLLs
libstdc++-6.dll & libgcc_s_dw2-1.dll (can be found in MinGW/bin)
Otherwise very, very simple to get the secret key |
2024-05-06 23:11 |

uses unknown versions of the MinGW-libraries. Better link them to the binary |

Very nice crackme!
Easy to crack & easy to find a valid user-password-combination.
But it was a bit difficult to find the function for the password calculation.
However, now my keygen works...

@cnathansmith Thank you for your support. I will dig into this approach. I think, I will stick with C++ for the time being until I am more familiar with the subject matter. |

| KeygenMe_SWD |
Damn it. I tested with dnSpy, it didn't give me the code. With ILSpy it's an easy task.
After some research I found out, that I could use a packer and obfuscator to hide the code. BUT I also learned, that nearly all of them could be bypassed in seconds.
So, is there a way to obfuscate the C#-code properly? Or is it all snake-oil and it's best to NOT use C# for crackmes? |
