FileLock is an application for locking and securing your files using a powerful encryption algorithm. It is password-based, meaning you enter a password to lock your files and then later enter that same password to unlock them.

Once your files have been encrypted into a locked file, you can do anything with it - email, send over IM/Skype, backup, upload, etc... Our locked format is entirely portable and can be easily opened by any copy of FileLock on any computer (provided the correct password is entered, of course).

Technical details:

  • 448-bit Blowfish encryption
  • Multithreaded internals for taking advantage more...
