使用PHP-GPG和Wordpress

Question

我正在开发一个实现，它应该从我的Wordpress安装gpg加密发送每个外发邮件。

我使用来自Tim Nash的教程构建了我的小插件，我使用了来自Jason Hinkle的php-gpg lib。当我从Wordpress 4.3发送电子邮件时，我收到了一个pgp加密的邮件，但我无法打开它，因为WP /我的插件使用了错误的公钥。我检查了一下，并在我的用户wp-profile中粘贴了正确的密钥，但是......没有：错误的密钥。你有什么想法吗？

list($gpg_usec, $gpg_sec) = explode(' ', microtime());
srand((float) $gpg_sec + ((float) $gpg_usec * 100000));
