Principles of our Technology

We encrypt your programs with a standard crypto algorithm and decrypt them before execution. The secret key or password is calculated on the fly and cannot be extracted using decompilation or other methods. This technology has been developed by BIS Guard & Co. and is its know-how.

Great work! For more than a year I'm looking for a good Antidecompiler that encrypts java byte code. All that I've seen is good obfuscators, and one Excelsior Jet Compiler that "encrypts" the java classes. I was very impressed by your work. I am dealing with java applications for few last years but I haven't seen such a pro team like yours.
