Hello,

I'm looking for a solution of modifying the GCJ. I want to encrypt java
source files while compiling so it results in encrypted .class files. The
Decryption should take place on-the-fly while execute the .class Files.

Could someone help me? What do I have to do or are there any good
information sources available???


regards
Toni

When generating class files, you could encrypt them in a separate
step.

Reading a .class file at runtime is done in libjava/defineclass.cc.
That is one place you could decrypt.
