I'm sure you all remember my program, Very Good Privacy, and have been waiting for the release of the new version with bated breath. Well, it's finally here! Only, after being contacted by PGP, Inc. regarding a possible trademark violation, I've changed its name to Kremlin. Remember: it's like an iron curtain for your data. The new version still uses the same algorithms. The algorithms can be grouped into three categories: ASCII and Vigenere, which give little security, but are extremely fast, DES, NewDES, and Safer SK-128, which will protect against all but the most well-funded adversaries, and Blowfish, IDEA, and RC4, which are perhaps the most secure algorithms available today. The key-size of the algorithms ranges from 64-bits (actually 56-bits) in DES to 128-bits in IDEA, NewDES, and Safer SK-128, and infinite length in ASCII, Blowfish (up to 448-bits), RC4, and Vigenere. If the "Hash Passkey" option is checked, then the passkeys are hashed with a 64-bit per-source file salt using SHA1 to form a 160-bit passkey; extra bits not used by the fixed-length algorithms are discarded. Without the "Hash Passkey" option checked, the passkey is only XORed with the salt and retains its original size. If the "Encrypt Headers" option is checked, then the filename and file size of the files are encrypted, giving an attacker no information about the source files. Once the files have been encrypted, you have the option of securely deleting them by overwriting them a user-definable number of times with random data; the most secure encryption algorithm in the world is useless if the plaintext is left unsecured on the hard drive. All of this is done through one simple dialog box. To launch Kremlin, just drag a file or directory (or a combination of files or directories) onto the Encrypt icon on the Windows 95 desktop. To decrypt a file, just double-click on it and enter the passkey; no unwieldy tabbed dialog boxes or file directory navigation boxes. Plus, as a added bonus, anyone who orders 10 or more copies of Kremlin will receive a can of Spam (TM) for free!
