Mailcrypt is an emacs lisp package that provides a simple but powerful interface to cryptographic functions for mail and news. with mailcrypt, encryption becomes a seamlessly integrated part of mail and news handling. mailcrypt can automatically fetch public keys to encode, decode, and verify messages; can be configured to automate mailing through anonymous remailers; and can interface to both gpg (the gnu privacy guard) and pgp.

although mailcrypt may be used to process data in arbitrary emacs buffers, it is most useful in conjunction with other emacs packages for handling mail and news. mailcrypt has specialized support for rmail, vm, mh-e, mew, and gnus.

xemacs ships with its own version of mailcrypt, so this package should only be used with gnu emacs. (i.e., you don't need to install this package if you only use xemacs.)
