LI. gnupg Funções

Introdução

This module allows you to interact with gnupg.

Atenção

Este módulo é EXPERIMENTAL. Isso quer dizer que o comportamento neste módulo --- incluindo suas funções e seus nomes, e TUDO mais que está documentado sobre esse módulo --- poderá mudar em futuras versões do PHP, SEM QUALQUER NOTIFICAÇÃO. Esteja avisado, e use este módulo por sua própria conta e risco.

Dependências

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

Instalação

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

Notas

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";

}

?>

Exemplos

This example will clearsign a given text.

Exemplo 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;

?>

Exemplo 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;

?>

(no version information, might be only in CVS)





gnupg_deletekey -- Delete a key





Description





bool gnupg_deletekey ( resource identifier, string key, [bool allowsecret]  )





Deletes the key from the keyring. If allowsecret is not set or FALSE it will fail on deleting secret keys.





Return Values





On success, this function returns TRUE. On failure, this function returns FALSE.





Examples





Example 1. Procedural gnupg_deletekey() example





<?php


$res = gnupg_init();


gnupg_deletekey($res,"8660281B6051D071D94B5B230549F9DC851566DC");


?>





Example 2. OO gnupg_deletekey() example


<?php


$gpg = new gnupg();


$gpg -> deletekey("8660281B6051D071D94B5B230549F9DC851566DC");


?>
