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.
