Keygen me with no obfuscation or anything like that, but a fairly complex validation system.
SYS_V on 10:29 PM 01/26/2020: ./keygenme: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by ./keygenme)
Carbon on 6:39 PM 02/04/2020: Yes, same thing on my side. It expects a dynamic library: GLIBC 2.29. I'm installing GNU Libc6 to see how it fixes this issue.
Carbon on 7:20 PM 02/04/2020: Ok I got it recompiled without the dependencies (that were not even needed). This command expects 2 parameters: Usage: ./keygenme has to be at least 4 characters long and needs to be 25 characters
Carbon on 7:22 PM 02/04/2020: Wow... the \ were eaten by the site.

ragnar_crackbeard87 on 12:42 PM 03/05/2020: IZIPIZI VBHPWYGBUTBOGPQJWYPBZAWPG Jk about the easy part though. It took me awhile to do but it was fun, so thank you! :)
BinaryNewbie on 10:14 PM 03/26/2020: Nice crackme @egg. The choice of the serial charset impacts a lot in the keygen performance, btw, thank you.
Zopazz on 7:56 AM 06/24/2020: Very fun crackme! Took me a while to get. I uploaded my solution
unc4nny on 11:56 AM 01/11/2021: @ragnar_crackbeard, would you mind sharing your solution? Mine goes like this (I plan on sharing it on solutions tab): ./keygenme $(python -c "print('E' * 464)") $(python -c "print('\x60'+'E' * 24)")
