XLVII. gnupg Functions

IntroducciÃ³n

This module allows you to interact with gnupg.

Aviso

Esta extensiÃ³n es EXPERIMENTAL. Esto significa que el comportamiento de esta extensiÃ³n, los nombre de sus funciones y en definitiva TODO lo documentado sobre esta extensiÃ³n, puede cambiar en una futura versiÃ³n de PHP SIN AVISO. La advertencia queda hecha, y utilizar esta extensiÃ³n queda bajo su propia responsabilidad.

Requisitos

The gnupg extension requires PHP 4.3. To use this extension in an OO style, PHP 5 is required.

This extension requires the gpgme library

InstalaciÃ³n

The gnupg-extension is not bundled with PHP. It is a PECL extension and can be located here: http://pecl.php.net/package/gnupg.

Notes

This extension makes use of the keyring of the current user. This keyring is normally located in ~./.gnupg/. To specify a custom location, store the path to the keyring in the environment variable GNUPGHOME. See putenv for more information how to do this.

Some functions require the specification of a key. This specification can be anything that refers to an unique key (userid, key-id, fingerprint, ...). This documentation uses the fingerprint in all examples.

keylistiterator

This extension also comes with an Iterator for your keyring.

<?php // create a new iterator for listing all public keys that matches 'example' $iterator = new gnupg_keylistiterator("example"); foreach($iterator as $fingerprint => $userid){ echo $fingerprint." -> ".$userid."\n"; } ?>

Ejemplos

This example will clearsign a given text.

Ejemplo 1. gnupg clearsign example (procedural)


<?php

// init gnupg

$res = gnupg_init();

// not really needed. Clearsign is default

gnupg_setsignmode($res,GNUPG_SIG_MODE_CLEAR);

// add key with passphrase 'test' for signing

gnupg_addsignkey($res,"8660281B6051D071D94B5B230549F9DC851566DC","test");

// sign

$signed = gnupg_sign("just a test");

echo $signed;

?>

Ejemplo 2. gnupg clearsign example (OO)


<?php

// new class

$gnupg = new gnupg();

// not really needed. Clearsign is default

$gnupg->setsignmode(gnupg::SIG_MODE_CLEAR);

// add key with passphrase 'test' for signing

$gnupg->addsignkey("8660281B6051D071D94B5B230549F9DC851566DC","test");

// sign

$signed = $gnupg->sign("just a test");

echo $signed;

?>
