简要概述GPG-Mailer API

/**
 * Import a public key, return the fingerprint
 *
 * @param string $gpgKey An ASCII armored public key
 * @return string The GPG fingerprint for this key
 */
public function import(string $gpgKey): string;

/**
 * Get the public key corresponding to a fingerprint.
 *
 * @param string $fingerprint
 * @return string
 */
public function export(string $fingerprint): string;

/**
 * Encrypt then email a message
 *
 * @param Message $message    The message data
 * @param string $fingerprint Which public key fingerprint to use
 */
public function send(Message $message, string $fingerprint);

/**
 * Email a message without encrypting it.
 *
 * @param Message $message The message data
 * @param bool $force      Send even if we don't have a private key?
 */
public function sendUnencrypted(Message $message, bool $force = false);

示例：使用您的GnuPG公钥加密发送的电子邮件

<?php
use \ParagonIE\GPGMailer\GPGMailer;
use \Zend\Mail\Message;
use \Zend\Mail\Transport\Sendmail;

// First, create a Zend\Mail message as usual:
$message = new Message;
$message->addTo('test@example.com', 'Test Email');
$message->setBody('Cleartext for now. Do not worry; this gets encrypted.');

// Instantiate GPGMailer:
$gpgMailer = new GPGMailer(
    new Sendmail(), 
    ['homedir' => '/homedir/containing/keyring']
);

// GPG public key for <security@paragonie.com> (fingerprint):
$fingerprint = '7F52D5C61D1255C731362E826B97A1C2826404DA';

// Finally:
$gpgMailer->send($message, $fingerprint); 

如果您使用用户提供的公钥加密（并且他们没有告诉您其指纹），请执行以下操作

<?php

/**
 * Output from: gpg --armor --export user@example.com
 *
 * This is our security team's GPG public key. You probably don't
 * want to use ours, as only we can decrypt the messages.
 *
 * @var string

// Then to import.

使用服务器的私钥签名电子邮件

已签名和加密

要添加签名，我们将签名密钥传递给GPGMailer构造函数的第三个参数。

<?php

use \ParagonIE\GPGMailer\GPGMailer;
use \Zend\Mail\Message;
use \Zend\Mail\Transport\Sendmail;

// First, create a Zend\Mail message as usual:
$message = new Message;
$message->addTo('test@example.com', 'Test Email');
$message->setBody('Cleartext for now. Do not worry; this gets encrypted.');

$signingKey = file_get_contents('tests/private.key');

// Instantiate GPGMailer:
$gpgMailer = new GPGMailer(
    new Sendmail(), 
    ['homedir' => '/homedir/containing/keyring'],
    $signingKey
);

// GPG public key for <security@paragonie.com> (fingerprint):
$fingerprint = '7F52D5C61D1255C731362E826B97A1C2826404DA';

// Finally:
$gpgMailer->send($message, $fingerprint); 

或者，我们也可以像上面定义构造函数，但此时使用setPrivateKey()如下所示

$gpgMailer = new GPGMailer(
    new Sendmail(), 
    ['homedir' => '/homedir/containing/keyring']
);

$signingKey = file_get_contents('tests/private.key');
$gpgMailer->setPrivateKey($signingKey);

已签名但未加密

与上面相同，但不需要加载收件人的指纹，我们使用sendUnencrypted()方法。

<?php
use \ParagonIE\GPGMailer\GPGMailer;
use \Zend\Mail\Message;
use \Zend\Mail\Transport\Sendmail;

// First, create a Zend\Mail message as usual:
$message = new Message;
$message->addTo('test@example.com', 'Test Email');
$message->setBody('Cleartext for now. Do not worry; this gets encrypted.');

$signingKey = file_get_contents('tests/private.key');

$gpgMailer = new GPGMailer(
    new Sendmail(), 
    ['homedir' => '/homedir/containing/keyring'],
    $signingKey
);

$gpgMailer->sendUnencrypted($message);
