PGP is a well respected internationally used public/private key cryptography system.
Public Key cryptography relies on the encryption key being made
public but the decryption key is private. By using our public key you can send us messages that only we can decrypt (once encrypted even the sender cannot decrypt it without the recipients private key).
Similarly to send you messages we need to know your public key.
The great advantage of this system is that you do not need to have a "trusted delivery" of the decryption keys. The public key,
as its name implies, is open to all. The private key always remains in your control.
PGP can also be used to "sign" an unencrypted message so that any alteration to it can be detected. Used in
this way the private key is used to generate a signature and the public key is used to check the authenticity of the message.
The international version of PGP we use is compatible with the US version but
not subject to control by the United States government. However overseas clients are reminded that it is their responsibility to conform with any local laws (if any) concerning the sending of encrypted messages to
and from their country. As at Jan 97 the countries we know who ban the private use of encryption are France, Russia, Iran, Iraq and China.
PGP is secure, multiplatform and easy to use, however setting
it up in the first place can be quite hard work. PGP is available in versions for DOS, Unix and Mac amongst others. It is also available for Windows 95/NT in version 6 which is a lot easier to set up than
the earlier DOS versions. If you are using Windows you might find it easier to use version 6 or a "shell" to to version 2.6 to give you a Windows front end to PGP. If you are not familiar with PGP we
recommend you look at one of the PGP sites below. Don't forget to bookmark this page first so you can find your way back.
