The Official Bytecode Club Crackme's - Konloch - 10-10-2014

I've only got 6 levels completed, they're targeted at beginners, so if you're experienced with Java Reverse Engineering please wait until I add more levels (Or help me add more levels).
Example launch command: java -cp crackme.jar the.bytecode.club.crackme.level1.Main passw0rd

Beta 1.0: http://the.bytecode.club/crackmes_b1.0.jar (6 levels)
Beta 2.0: http://the.bytecode.club/crackmes_b2.0.jar (7 levels + obfuscation)

I must have fallen asleep for a few days and miss these. Thanks for the releases. Looking forward to the rest of them.

Great challenges.
Would be a little harder if the md5 hashes were different and couldn't be looked up online.. Tongue

Haha, I've been meaning to more dedicate some time to this. If you'd like to collab with me I could put this on github and we could work on this further.

I've added beta 2.0, contains heavy obfuscation + level 7.

I'll be leaving 1-6 unobfuscated in the next version, for now they're obfuscated.

Level 5 of Beta 2.0 appears to be broken, you can input anything and it spits out "Cracked"
