Today, my colleague was surprised to tell me that I found an online EditPlus registration code generator, and I hurried to look at it, and really, here.
EXE registration machine virus too many, pure JS online registration machine can be relieved.
The author is from other people's registration machine disassembly and then find the algorithm, but also to my surprise, this author Demon unexpectedly is engaged in law, just get the legal professional qualification certificate, admire.
One of the main JS functions is this:
Copy Code code as follows:
