Cryptainer LE enables you to create a secure container on your PC, using powerful 128 bit strong encryption - without changing the way you work. The software creates new virtual drive letter(s), and all files that are added to this drive are encrypted on-the-fly. You can also create a secure storage container on any media including external and removable drives (e.g. USB drives, CD etc). The drive letter is accessible through Windows Explorer just like any other drive - as long as you are logged into the Cryptainer PE interface. If the program is terminated, the files in the secure drive are no longer accessible to other users - you can access them at any time by logging in with your password. Using this method, you can automatically keep a secure area, that can only be accessed by you, without having to encrypt individual files manually - just login once. In addition, Cryptainer LE allows you to send files with encrypted email messages, using self-decrypting EXE attachments that do not require any software to be installed by the recipient. The free version is limited to a container size of 25 mb, however you can create an unlimited number of such 25 mb containers.
