MIT distribution site for PGP
(Pretty Good Privacy) 
PGP or Pretty Good (TM) Privacy is a high-security cryptographic software application that allows people to exchange messages with both privacy and authentication.
Privacy means that only those intended to receive a message can read it. By providing the ability to encrypt messages, PGP provides protection against anyone eavesdropping on the network. Even if a packet is intercepted, it will be unreadable to the snooper. Authentication ensures that a message appearing to be from a particular person can have originated from that person only, and that the message has not been altered. In addition to its support for messages, PGP also enables you to encrypt files stored on your computer.
MIT distributes PGP free for non-commercial use. This distribution is done in cooperation with Philip Zimmermann, the author of PGP, and with RSA Data Security, Inc., which licenses patents to the public-key encryption technology on which PGP relies. 


MIT is also distributing . 


How to obtain PGP from MIT
PGP is distributed by MIT only to US citizens in the United States, or to Canadian citizens in Canada.
MIT distributes PGP both in source and in and executable only versions. PGP is available for most DOS, Macintosh, and Unix platforms. The current versions of PGP being distributed by MIT are:
For DOS and Unix platforms, MIT has been distributing PGP version 2.6.2 since October 24, 1994.
For the Apple Macintosh, MIT has been distributing MacPGP version 2.6.2 since May 17, 1995.
To obtain the current version of PGP from MIT via the World-Wide Web, click . 
If you do not have WWW access, you can use anonymous FTP to net-dist.mit.edu. Look in the directory pub/PGP and follow the directions in the README file.
PGP is available from MIT by WWW or FTP access only. If you do not have such access you will need to obtain PGP from another source. 


Integrating PGP with mail programs
PGP is much more convenient to use in conjunction with an interface that integrates it into programs for reading and sending mail. Several such interfaces are available for popular mail programs. The ones distributed by MIT are:
For users of Emacs on Unix systems, there is Mailcrypt, available from MIT. .
For users of Eudora on the Apple Macintosh, there are Eudora/MacPGP scripts that provide an interface to PGP. These scripts are included in the MIT MacPGP2.6.2 distribution. .
Here are some other PGP/mail interfaces (not distributed by MIT):
For users of MH mail on Unix, exmh is an X Window System user interface to MH mail, which provides PGP support. You can find information about exmh .
 is a PGP-based e-mail encryption package for use with PGP and offline mail readers on DOS machines.
Fran Litterio maintains an extensive list of PGP-related utilities and interfaces to various mailers. You can find this .


Public Keyservers
Once you get PGP and start using it, you might want to consider using the  that is available on the Web. Alternatively, you can learn how to use the  to add your key to the public keyservers.
