BCArchive

This free encryption utility earns points for its ease of use, security, and speed. Although BCArchive's spartan interface makes it pretty clear how to create secure archives, many users may prefer to encrypt files via the right-click menu. Similar to most quality programs of this type, BCArchive can create self-decrypting files, so your recipients won't have to bother with installing the program themselves. All other users will need your password if they want to access your sensitive documents. It's nice that the application supports multiple secure algorithms, including Triple DES, Blowfish, and Rijndael. However, unlike many of the top applications in this class, BCArchive lacks a file shredder for destroying data. Still, on most other fronts, this encryption tool makes a strong case for itself.
