Looking for a simple, powerful way to protect files on your PC from prying eyes? Then you'll want this program. It lets you encrypt and password protect any file on your hard disk so that only those with the proper password will be able to read them. It uses powerful encryption algorithms, including AES 256 bit/192 bit/128 bit; TripleDES 192 bit; and DES 64 bit. Passwords can be up to 32 characters in length.
It offers plenty more as well. You can compress the files as you encrypt them, to save on hard disk space. The program will also scramble your entire hard disk, if you want to get rid of all of its data. It's exceedingly easy to use, and it can either run as its own interface or integrate into Windows Explorer.
