Go

Load .eml and Decrypt (smime.p7m)

Loads an encrypted email from a .eml file and decrypts using certificate w/ private key found in a .p12 (or .pfx) file.

The Content-Type and Content-Disposition email headers of the email to be decrypted look similar to this:

Content-Type: application/x-pkcs7-mime; smime-type=enveloped-data;
	name="smime.p7m"
Content-Disposition: attachment; filename="smime.p7m"

Go

    success := false

    email := chilkat.NewEmail()

    // Add a PFX (or .p12) to be used for decryption
    success = email.AddPfxSourceFile("myCert.p12","passwordForP12")
    if success != true {
        fmt.Println(email.LastErrorText())
        email.DisposeEmail()
        return
    }

    // Loading the .eml automatically decrypts.
    success = email.LoadEml("encrypted.eml")
    if success != true {
        fmt.Println(email.LastErrorText())
        email.DisposeEmail()
        return
    }

    // The email now exists as it was prior to encryption.
    // Your app may access the email's subject, body, attachments,
    // etc. using the Chilkat Email API...

    // Save the decrypted email:
    success = email.SaveEml("decrypted.eml")
    if success != true {
        fmt.Println(email.LastErrorText())
        email.DisposeEmail()
        return
    }

    fmt.Println("Success.")

    email.DisposeEmail()
