Send Signed and Encrypted EDI Email (EDIFACT)

Demonstrates how to send a signed and encrypted EDI email (EDIFACT email). PHP ActiveX

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

//  The mailman object is used for sending and receiving email.
$mailman = new COM("Chilkat.MailMan");

//  Create a new email object

//  Build the basic EDI email where the body is the EDIFACT message:
$ediMsg = 'UNB+IATB:1+6XPPC ...';
$name = 'something';
$filename = 'something';
$charset = 'iso-8859-1';
$email->SetEdifactBody($ediMsg,$name,$filename,$charset);

$email->Subject = 'This is the subject';
$email->From = 'Chilkat Admin <admin@chilkatsoft.com>';
$success = $email->AddTo('Chilkat Support','support@chilkatsoft.com');

//  Indicate that the email should be sent signed.
$email->SendSigned = 1;

//  Tell the mailman to use a PFX file as a source for locating
//  the certificate and private key required for signing.
//  The certificate chosen for signing will be the one that
//  matches the sender's email address, which also has
//  a private key.  All intermediate certs in the chain of
//  authentication, up to and including the root, will
//  be included in the signature.
$success = $mailman->AddPfxSourceFile('/pfx_files/myCertAndPrivateKey.pfx','secret');

}

//  Load the .cer file into a certificate object.
//  When sending S/MIME encrypted email, it is the recipient's
//  certificate that is used for encryption.  Only the public key
//  is needed to encrypt.  The recipient is the only
//  one possessing the private key, and therefore is the only
//  one able to decrypt.

$success = $cert->LoadFromFile('/certs/recipientCert.cer');

//  Indicate that we want 192-bit 3DES encryption:
$email->Pkcs7CryptAlg = '3des';
$email->Pkcs7KeyLength = 192;

//  Specify the certificate to be used for encryption.
$success = $email->SetEncryptCert($cert);

//  Tell the mailman to use an opaque signature (as opposed to a detached signature)
$mailman->OpaqueSigning = 1;

//  SMTP server (use your settings and refer to the online
//  reference  documentation for more options)
