Anmerkungen

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";
}
?>

Beispiele

This example will clearsign a given text.

Beispiel 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;
?>

Beispiel 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;
?>
