user: a
serial is: f
take 'a' and get ASCII '65' and xor with 4
and add 1 then get the char of the result
result= (65^4)=69
result+=1
result=70 // f in ASCII

// Key Gen Idea
1) Randomly generate a string (Try to do it between 'A' and 'Z'
2) Create a key variable "key" to store the generated key
3) for each character c in the generated string: add c ^ 4 + len(generated string) to key.
4) Send in the generated string as User and key as Serial.

GOOD JOB BRO! CONTINUE!
Solution by Blepperton on 2021-11-20 05:55: Writeup to the crackme + Keygen AND Reversed Sourcecode.
Perfect solution for those that want to compare the assembly to sourcecode to make more sense out of it.
