Kremlin is an encryption utility that seriously improves the privacy of your files. At its simplest, Kremlin will take a file and encrypt it using one of six algorithms, including RC4, DES, IDEA or Blowfish, with keys up to 160bits long. This is so secure that the US government considers it ammunition!

Encrypting is as easy as right-clicking the file in question and selecting Kremlin Encrypt. The resulting encrypted file has the rather apt '.kgb' file extension.

Kremlin also offers a secure recycling bin on your desktop, the contents of which are permanently deleted straightaway just like a digital shredder.

On top of all this, Kremlin can be set to wipe your virtual memory swap file, along with all histories on a regular basis or at shutdown.
