* What's this?

EasyPG is yet another GnuPG interface for Emacs.  It consists of two
parts: transparent file encryption utility and easy-to-use elisp
library to interact with GnuPG.

* Requirements

** GNU Emacs 21.4 or later
** XEmacs 21.4 or later
** GnuPG 1.4.3 or later

* Quick start

(0) Put (require 'epg-file) in your ~/.emacs.el

(1) Restart emacs

(2) C-x C-f ~/test.gpg

* Advantages over other competitors

** EasyPG avoides potential security flaws of Emacs.

*** `call-process-region' writes data in region to a temporary file.
PGG and gpg.el use `call-process-region' to communicate with a
subprocess "gpg".  So, your passphrases may leak to the filesystem.

*** There is no way to clear strings safely.
To prevent passphrases from been stealing from cores, `read-passwd'
function clears passphrase strings by `(fillarray string 0)'.
However, it is not enough.  Emacs does compaction of small strings in
GC sweep phase.  If GC happens before `fillarray', passphrase strings
may be copied elsewhere in the memory.  PGG and gpg.el enables
passphrase caching by default.

** Most GnuPG features can be accessible from Emacs
As the name says, EasyPG is inspired by GPGME (GnuPG Made Easy), and
the API is close to GPGME.
