Electronic letters

    Letters differ from cards in that they have an envelope. Electronic envelopes can be supplied via public key encryption. The content of a message is decipherable only by the recipient and the sender can be authenticated.

Why use envelopes?

    The psychological atmosphere of sending and receiving plain e-mail is that of a private conversation. Well ... it is NOT private. In fact, a minimum of sophistication is required to gain access to e-mail or to fake outgoing e-mail.

Where to get envelopes

    Download the PGP program (Pretty Good Privacy) and install it on your machine (easy).

How to use envelopes

    Follow the instructions with pgp and add my public key to your key ring. Then use pgp to encrypt your message before mailing it to gokhman@math.utsa.edu

    If you want to have me encrypt my replies to you, e-mail me your public key, or publish it via your home page or a keyserver.
