Frequently Asked Questions

Dekart RSA Cryptographic Provider

Private Disk related

• If I use an external hard disk, does that increase the chance to lose data?
• If I create a huge virtual encrypted image and somehow something goes wrong, then I sort of lose a lot of files, don't I?

Dekart Logon related

• If I logon in safe mode, your program is not active, isn't this a security flaw?
• When I create a key on a USB disk, a file is created on it (smartkey.dka). Anyone can copy it on a different disk and then use my workstation. Isn't this a severe problem?

• Why Dekart Private Disk is more secure than Dekart Private Disk Light?
• Can I store encrypted volumes on recordable CD disks, CD-RW disks or USB flash disks?
