Cryptic Disk creates virtual encrypted disks and also encrypts hard disks, USB drives and memory cards. Data encryption makes use of the best algorithms (AES/Rijndael, Serpent, Twofish, Blowfish, CAST6), and takes place in real time without affecting computer performance.
Cryptic Disk is an easy in use application with a pretty friendly user interface.
Just click on the disk letter in the Cryptic Disk control panel and run "Encrypt Volume" task. Follow the on screen instructions and your disk will become protected in a moment. Or if you don't want to protect the whole disk, simply run Create Encrypted Container task - this will create a virtual encrypted volume for you.
