File encryption, the Mac way

We regret that due to a lack of resources to enhance and support the product, FileLock is no longer available for purchase. We will continue to make it available to download so that you may decrypt any .locked archives you may have; decryption does not require a license key. We extend our thanks to all of our customers for your support.

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
  • Threaded internals for excellent efficiency
  • Architecture independent file format (Intel and PowerPC)
  • Limitless in terms of maximum file size or amount of data
  • Built on the trusted and proven OpenSSL library bundled with OS X (More info)

Trial information:
  • 14 day fully-featured trial
  • When the trial has expired FileLock will not allow you to lock new files, but will always allow files to be unlocked. We never take away your ability to decrypt existing locked files.
