Two crackme's coded in VB (yes, vb...)

v1.0 is kinda easy, v2.0 i dunno, nobody tried it soo gave it a try Smile

Try to patch it first, then figure the password.

(v1.0 - Wiccaan found it.)
(v2.0 - Nobody... yet.)

Have fun.

Side note : in v1.0, there is NO code problem, make sure the code that you see is really getting executed =)

Credits to Sunbeam for testing the v2.0 (RC4 encryption fails)

Please, no use of VB Decompiler, this removes the challenge.

Ahh, I keep having problems with this fucking v2, it works fine here but doesn't for some people, but does for others.

I have no idea why it did a such thing to be honest, ill try to work on it

Congrats on the 1st one, can you find the pass yet?
