Thx to everybody
for the answers, but my file is cripted. It use a class file and an extern file .bin. I have decripted the first part, and i suppose to have understand the next part of cripting .
But if anybody knows tuts with examples of java cripted files plz tell me.

thx again and bye

Well, what kind of encryption is it? DES? Blowfish? Vigniere cipher?
Truncated linear conguential generator?

If you can't tell, send me the decompiled code & I'll have a look.

If it's strong encryption, the best you'll be able to do is a dictionary attack.

Hi mike,
I don't know the name of the encrypt. The prg is VisualRoute 5.0b.
It is composed of 2 principal files:
vr.bin and vr.class
I have decompiled vr.class with jad, and i have found a first decrypt of vr.bin. I have added my save routine in Java and compiled it again. This patch save the new file. I have JADed this new file, cos it is a class, but a new loading of bin is maked. Sorry for ambiguos post, but if u want look at this prg.

Thx & bye

So there's no password, just a fixed transform to unobscure the code. That ought to be easy to reobscure; just invert the "crypting" code to create a new bin file, or remove the decryption code entirely from the class file and just load the decrypted one directly.
