TNTCrypter is a free professional quality app for hashing and encrypting your files.
While TNTCrypter has a lot of capabilities and features, the main interface follows the keep it simple stupid (KISS) format we like here. Text options are on the left, pictures in the middle and files on the right. With text, you can convert, generate a hash, or encryptdecrypt. If you need to go back at any time, there's a menu link in the lower right of each window. Across the top, you can find File, Modules, Options, License, About, and Donate.
