    FreeOTFE

    FreeOTFE

    A free "on-the-fly" transparent disk encryption program for PC & PDAs.

    An upstream source site housing the original files for this mirror is no longer available. With this software, you can create one or more "virtual disks" on your PC/PDA. These disks operate exactly like a normal disk, with the exception that anything written to one of them is transparently, and securely, encrypted before being stored on your computer's hard drive.
