pretty simple crackme, just find the logic behind key validation and write a key gen :) key isnt hard coded btw. This is my first crackme so let me know how I did!

stevefan1999 on 2020-01-05 07:27: total length must be 5 first character can be anything second character must be '@' the rest (3-5) their sum of integer value of ascii character must be 300

Maksim on 2020-01-11 17:58: first checks the key length (len must be 5), then checks the second character of the key (must be "@"), finally checks the last 3 characters, their sum in the ascii code must be 300, the first character can be any eg: 1@ddd

ezman on 2020-01-29 15:38: This was a pretty fun one, especially for a beginner like myself. I learned a lot by doing this one, so thanks! It was also pretty fun.

Th3R3dP1ll on 2020-02-10 14:04: I liked this one, I found figuring out what the program did pretty easy and learnt a bit about python3 to generate the keys :)

ShiroiAkuma on 2020-02-22 08:51: Really had fun, this was my first crackmes. Procedure was easy, I did get lost on MOVXZ and MOVSZ but once I figured it out it was smooth.

antid0t3 on 2020-12-22 16:08: nice crackme. why that name tho?

hackingmaterials on 2021-07-20 12:51: I did p@ddd (where the ascii value of @ is 40, and d is 100) 1. length is 5 2. second letter is @ 3. sum of 3rd 4th and 5th is 300 i got .. nice one! Now, can you keygen me?

This was my first crackme to solve and pretty fun. Writing the keygen should be trivial from here on.

Simple writeup and the python keygen, capable of generating all possible keys using the standard set of printable ASCII characters (32 to 126).

This was fun, first keygen I've written.

My solution about the logic that I followed to solve the problem plus the keygen.cpp, using ascii values from 48-122 (0-z) to generate the random string. Also able to generate N keys.

Notes at the top of the file, keygen in the rest. Looking around at the other solutions, seems my write-up skills are sub-par, guess I'll work on that as well as my re.
