/**
* This example shows signing a message and then sending it via the mail() function of PHP.
*
* Before you can sign the mail certificates are needed.
*
*
* STEP 1 - Creating a certificate:
* You can either use a self signed certificate, pay for a signed one or use free alternatives such as StartSSL/Comodo etc.
* Check out this link for more providers: http://kb.mozillazine.org/Getting_an_SMIME_certificate
* In this example I am using Comodo.
* The form is directly available via https://secure.comodo.com/products/frontpage?area=SecureEmailCertificate
* Fill it out and you'll get an email with a link to download your certificate.
* Usually the certificate will be directly installed into your browser (FireFox/Chrome).
*
*
* STEP 2 - Exporting the certificate
* This is specific to your browser, however, most browsers will give you the option to export your recently added certificate in PKCS12 (.pfx)
* Include your private key if you are asked for it.
* Set up a password to protect your exported file.
*
* STEP 3 - Splitting the .pfx into a private key and the certificate.
* I use openssl for this. You only need two commands. In my case the certificate file is called 'exported-cert.pfx'
* To create the private key do the following:
*
* openssl pkcs12 -in exported-cert.pfx -nocerts -out cert.key
*
* Of course the way you name your file (-out) is up to you.
* You will be asked for a password for the Import password. This is the password you just set while exporting the certificate into the pfx file.
* Afterwards, you can password protect your private key (recommended)
* Also make sure to set the permissions to a minimum level and suitable for your application.
* To create the certificate file use the following command:
*
* openssl pkcs12 -in exported-cert.pfx -clcerts -nokeys -out cert.crt
*
* Again, the way you name your certificate is up to you. You will be also asked for the Import Password.
* To create the certificate-chain file use the following command:
*
* openssl pkcs12 -in exported-cert.pfx -cacerts -out certchain.pem
*
* Again, the way you name your chain file is up to you. You will be also asked for the Import Password.
*
*
* STEP 3 - Code

//Create a new PHPMailer instance

//Convert HTML into a basic plain-text alternative body
$mail->msgHTML(file_get_contents('contents.html'), dirname(__FILE__));
//Replace the plain text body with one created manually
$mail->AltBody = 'This is a plain-text message body';
//Attach an image file
$mail->addAttachment('images/phpmailer_mini.png');
//Configure message signing (the actual signing does not occur until sending)
$mail->sign(
'/path/to/cert.crt', //The location of your certificate file
'/path/to/cert.key', //The location of your private key file
'yourSecretPrivateKeyPassword', //The password you protected your private key with (not the Import Password! may be empty but parameter must not be omitted!)
'/path/to/certchain.pem' //The location of your chain file
);
//Send the message, check for errors
if (!$mail->send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}
/**
* REMARKS:
* If your email client does not support S/MIME it will most likely just show an attachment smime.p7s which is the signature contained in the email.
* Other clients, such as Thunderbird support S/MIME natively and will validate the signature automatically and report the result in some way.
