Code protection is based on 100% optimised compiled bytecodes, plus several layers of encoding on top. Never restoring files back to source is essential for true security. By eliminating source code before your files are encoded, and pre-parsing, compiling and optimising the compiled binary code, delivers the maximum possible protection, runtime performance and language compatibility. Encoded files are also protected by digital signatures, and any change to an encoded file, such as tampering with your PHP product's copyright text, renders the encoded file unusable.

Lesser solutions use code lock techniques that merely hide source code. Claims of uncrackable code and bulletproof encoding from such systems may sound convincing, but in these weaker systems, the source encoded files will be restored to original source code at runtime, and the reality is that this restored code can be very easily intercepted and exposed with minimal effort and skill. With other potential problems of less than 100% language compatibility and poor performance, compiled code protection is the clear winner and preferred technique.
