php-gpg
|
||||
=======
|
||||
|
||||
php-gpg is a pure PHP implementation of GPG/PGP (currently supports encryption only). The library does not require PGP/GPG binaries and should run on any platform that supports PHP.
|
||||
|
||||
This library is useful for encrypting data before it is sent over an insecure protocol (for example email). Messages encrypted with this library are compatible and can be decrypted by standard GPG/PGP clients.
|
||||
|
||||
Features/Limitations
|
||||
--------------------
|
||||
|
||||
* Supports RSA, DSA public key length of 2,4,8,16,512,1024,2048 or 4096
|
||||
* Currently supports only encrypt
|
||||
|
||||
Hey You! If you have a good understanding of public key encryption and want to implement signing or decryption your pull request would be welcome.
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
```php
|
||||
require_once 'libs/GPG.php';
|
||||
|
||||
$gpg = new GPG();
|
||||
|
||||
// create an instance of a GPG public key object based on ASCII key
|
||||
$pub_key = new GPG_Public_Key($public_key_ascii);
|
||||
|
||||
// using the key, encrypt your plain text using the public key
|
||||
$encrypted = $gpg->encrypt($pub_key,$plain_text_string);
|
||||
|
||||
echo $encrypted;
|
||||
|
||||
```
|
||||
|
||||
License
|
||||
-------
|
||||
|
||||
GPL http://www.gnu.org/copyleft/gpl.html
|
||||
|
||||
I'd like to release this under a more permissive license, but since PGP & GPG itself are GPL, I think this library is likely bound to the terms of GPL as well.

/**
|
||||
* Pure-PHP implementation of AES.
|
||||
*
|
||||
* Uses mcrypt, if available/possible, and an internal implementation, otherwise.
|
||||
*
|
||||
* PHP versions 4 and 5
|
||||
*
|
||||
* If {@link Crypt_AES::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
|
||||
* {@link Crypt_AES::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's 136-bits
|
||||
* it'll be null-padded to 192-bits and 192 bits will be the key length until {@link Crypt_AES::setKey() setKey()}
|
||||
* is called, again, at which point, it'll be recalculated.
|
||||
*
|
||||
* Since Crypt_AES extends Crypt_Rijndael, some functions are available to be called that, in the context of AES, don't
|
||||
* make a whole lot of sense. {@link Crypt_AES::setBlockLength() setBlockLength()}, for instance. Calling that function,
|
||||
* however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one).
|
||||
*
|
||||
* Here's a short example of how to use this library:
|
||||
* <code>
|
||||
* <?php
|
||||
* include 'Crypt/AES.php';
|
||||
*
|
||||
* $aes = new Crypt_AES();
|
||||
*
|
||||
* $aes->setKey('abcdefghijklmnop');
|
||||
*
|
||||
* $size = 10 * 1024;
|
||||
* $plaintext = '';
|
||||
* for ($i = 0; $i < $size; $i++) {
|
||||
* $plaintext.= 'a';
|
||||
* }
|
||||
*
|
||||
* echo $aes->decrypt($aes->encrypt($plaintext));
|
||||
* ?>

* Pure-PHP implementations of keyed-hash message authentication codes (HMACs) and various cryptographic hashing functions.

*
|

* Uses hash() or mhash() if available and an internal implementation, otherwise. Currently supports the following:
|

*
|

* md2, md5, md5-96, sha1, sha1-96, sha256, sha256-96, sha384, and sha512, sha512-96

*
|

* If {@link Crypt_Hash::setKey() setKey()} is called, {@link Crypt_Hash::hash() hash()} will return the HMAC as opposed to

/**
|
||||
* Pure-PHP implementation of RC4.
|
||||
*
|
||||
* Uses mcrypt, if available, and an internal implementation, otherwise.
|
||||
*
|
||||
* PHP versions 4 and 5
|
||||
*
|
||||
* Useful resources are as follows:
|
||||
*
|
||||
* - {@link http://www.mozilla.org/projects/security/pki/nss/draft-kaukonen-cipher-arcfour-03.txt ARCFOUR Algorithm}
|
||||
* - {@link http://en.wikipedia.org/wiki/RC4 - Wikipedia: RC4}
|
||||
*
|
||||
* RC4 is also known as ARCFOUR or ARC4. The reason is elaborated upon at Wikipedia. This class is named RC4 and not
|
||||
* ARCFOUR or ARC4 because RC4 is how it is referred to in the SSH1 specification.
|
||||
*
|
||||
* Here's a short example of how to use this library:
|
||||
* <code>
|
||||
* <?php
|
||||
* include 'Crypt/RC4.php';
|
||||
*
|
||||
* $rc4 = new Crypt_RC4();
|
||||
*
|
||||
* $rc4->setKey('abcdefgh');
|
||||
*
|
||||
* $size = 10 * 1024;
|
||||
* $plaintext = '';
|
||||
* for ($i = 0; $i < $size; $i++) {
|
||||
* $plaintext.= 'a';
|
||||
* }
|
||||
*
|
||||
* echo $rc4->decrypt($rc4->encrypt($plaintext));
|
||||
* ?>
|

|

* </code>
|

|

* The solution is to enable the continuous buffer. Although this will resolve the above discrepancy, it creates
|

* another, as demonstrated with the following:
|

*
|

* <code>
|

* $des->encrypt(substr($plaintext, 0, 8));

* With the continuous buffer disabled, these would yield the same output. With it enabled, they yield different

* outputs. The reason is due to the fact that the initialization vector's change after every encryption /
|
||||
* decryption round when the continuous buffer is enabled. When it's disabled, they remain constant.
|
||||
*
|
||||
* Put another way, when the continuous buffer is enabled, the state of the Crypt_DES() object changes after each
|
||||
* encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that
|
||||
* continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them),

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.
|
||||
* Helper class for verifying, signing, encrypting, and decrypting messages using Crypt_RSA from <http://phpseclib.sourceforge.net>
|
||||
* Helper class for encrypting and decrypting messages and keys using Crypt_AES and Crypt_TripleDES from <http://phpseclib.sourceforge.net>
|
||||
|
||||
Users
|
||||

|
||||
|
||||
OpenPGP.php is currently being used in the following projects:
