    <?php

    $res = gnupg_init();
    // not really needed. Clearsign is default
    gnupg_setsignmode($res,GNUPG_SIG_MODE_CLEAR);
    // add key with passphrase 'test' for signing
    gnupg_addsignkey($res,"8660281B6051D071D94B5B230549F9DC851566DC","test");
    // sign
    $signed = gnupg_sign($res,"just a test");
    echo $signed;
    ?>

### 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");

    foreach($iterator as $fingerprint => $userid){
        echo $fingerprint." -> ".$userid."\n";
    }
    ?>
