OpenPGP.php: OpenPGP for PHP
|
||||
============================
|
||||
|
||||
This is a pure-PHP implementation of the OpenPGP Message Format (RFC 4880).
|
||||
|
||||
* <http://github.com/bendiken/openpgp-php>
|
||||
|
||||
### About OpenPGP
|
||||
|
||||
OpenPGP is the most widely-used e-mail encryption standard in the world. It
|
||||
is defined by the OpenPGP Working Group of the Internet Engineering Task
|
||||
Force (IETF) Proposed Standard RFC 4880. The OpenPGP standard was originally
|
||||
derived from PGP (Pretty Good Privacy), first created by Phil Zimmermann in
|
||||
1991.
|
||||
|
||||
* <http://tools.ietf.org/html/rfc4880>
|
||||
* <http://www.openpgp.org/>
|
||||
|
||||
Features
|
||||
--------
|
||||
|
||||
* Encodes and decodes ASCII-armored OpenPGP messages.
|
||||
* Parses OpenPGP messages into their constituent packets.
|
||||
* Supports both old-format (PGP 2.6.x) and new-format (RFC 4880) packets.
|
||||
|
||||
