File encryption, the Mac way.

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 of multiple cores
• Architecture-independent (Intel and PPC)
• Limitless in terms of maximum file size or amount of data
• Built on the trusted and proven OpenSSL library bundled with Mac OS X
