For example, if ‘a’ purchases vmprotect and protects a binary with it, Does the protected binary have information about ‘a’?
Yes it does.
Sorry for necropost, is the licensee’s information visible in plaintext on output binaries? If “John Doe” were to purchase your software, will “John Doe” be visible if I were to open the binary with Notepad.
Protected binaries don’t contain any “visible” information about licensee like “John Doe”, etc.
