Exe Protect
From Just Solve the File Format Problem
Exe Protect by Frederic Collin is a password-protection utility for Win32 programs. It makes programs require a password to run.
It works by 'encrypting' the original exe and renaming it with a ~ to start. Then it replaces the original exe with a stub of the same name.
- test.exe (original program)
becomes
- test.exe (Exe Protect stub)
- ~est.exe (encrypted program)
