Cryptainer LE is free, 128-bit file- and disk-encryption software. It encrypts and password protects any file or folder on any PC. Cryptainer LE works with all versions of Windows as well as with any kind of media, including CD-ROMs and any external drive, including USB and pen. It creates encrypted "vaults" within which you can store any kind of data.

The program also lets you create secure e-mail files you can send to anyone, and it ensures complete security for your data making, so only you can access your data. Cryptainer LE creates an encrypted volume that can be accessed only with your password. Once mounted, the volume behaves as a standard Windows drive. It runs on any 32-bit version of Windows (95/98/Me/2000/XP/Server 2003) and on all media.
