如何使用PHP发送带有附件的gpg加密电子邮件？

Question

I am looking for an easy way in PHP to send GPG encrypted emails with attachments.

I understand the individual pieces on how to send emails, how to use gpg command line and how MIME works. But I am interested in existing libraries. So that I don't re-invent the wheel on a low level.

The encrypted emails will be reading using Thunderbird with Enigmail.

Answer 1

There's a GnuPG extension , failing that you're best off using exec() and friends to invoke the regular gpg binaries. There's a decent Zend article showing hints for the latter approach

Answer 2

There is ongoing work at PEAR to accomplish this; see https://pear.php.net/bugs/bug.php?id=20938

Answer 3

You may try php-gpg from https://github.com/jasonhinkle/php-gpg

It supports the encryption using a public key.
