If you have information you wish to keep private (bank records, credit card numbers, tax returns, your spouse’s clothing sizes on your Christmas shopping list, etc.), you need to make sure that the information doesn’t fall into the hands of hackers, credit card thieves, and other strangers. One way to do that is to use encryption to make sure the information can not be read by anyone who does not know the encryption key.
Several encryption services and devices are available. One of the newer ones is the Kingston IronKey D300 encrypted USB flash drive that recently was certified for storage of NATO Restricted Level files. If it’s good enough to protect NATO’s secrets, it is probably good enough for you and me!
The IronKey D300 is available in capacities from 4GB up to 128GB.

Comment: There are other, cheaper ways to encrypt the contents of a flash drive by using software. However, I doubt if any software solution will ever get certified for NATO’s secrets. Also, the use of a flash drive with encryption already installed at the factory is undoubtedly simpler to use.
