Really neat product
wasoldchiefnerdApril 5, 2011
Pros
Easy, seems to work, automatically re-encrypts after working on document
Cons
Really have to buy the product to get full benefit. This is really only a demo.
Summary
Like the automatic decryption, re-encryption, neat idea, eliminates one insecurity.
Does what is says on the package - very easy to use

Pros
Very easy to use. Got an Amazon voucher for filling out the survey. Neat interface. Like the idea of not having my data on the stick.
Cons
Not suitable for large files such as videos.
Summary
I'm going to try it for a couple of weeks but will probably buy the full version.
VIRUS INSIDE - STAY AWAY

Pros
nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn
Cons
Clam win antivirus has detected a un virus in the file exe
Summary
AS ABOVE Updated on Apr 1, 2011With more time at my disposition I visited the website of the producer of this article, and I became aware of the innovative features of the same product. Then I do not really believe that in the file "demo" can actually be a virus, but probably antivirus that I used has detected a false positive. The product in question seems worthy of the best consideration at all.

Developer’s Description

By DataDiscretion

Encrypt your own vital documents.

One-time-pad is the only technique that can withstand any current or future attack because it uses randomly generated data that a computer cannot predict. DataDiscretion provides this one-time-pad capability, previously dismissed as impractical, in a convenient simple to use device. DataDiscretion uses the metaphor of key, understandable to anyone. This key enables the user to encrypt document quickly, simply and reliably via their USB port. Should a key be lost the customer can make a replacement using their KeyMaker. Unlike other solutions, we offer products that allow you to store information wherever convenient for you. Nothing is stored on the key. Should a key be lost the customer can make a replacement using their KeyMaker. No downloads or installation means that the product can be used on any Windows network, computer or laptop. Our products work on all file types and do not require a password. We offer the maximum security, whilst using our elegantly simpler user-interface. Our products automatically re-encrypt documentation previously encrypted, eliminating the possibility of human error.
