Description

SECUREDEVICE is a device driver that will help you keep your private data private. It creates extra drives on your system that are accessible just like normal disk drives, but everything you transfer to the volume will be encrypted using the IDEA encryption algorithm, and when you transfer data from the volume it will be automatically decrypted. Warning: This program uses strong encryption to protect data and it is not legal for individuals outside the USA to download it. If you do so, you may be breaking US law. Copyright GNU GPL.

Send to my palmtop

The palmtop must be waiting before you press the button, or the transfer will fail. It is the palmtop that announces it is ready, not the other way round.
