#  Build a simple MIME message to be encrypted:
mime.AddHeaderField("Content-Type","text/plain")
mime.AddHeaderField("abc","123")
mime.SetBody("This is a test")

#  A digital certificate is required to create PKCS7 encrypted MIME.
#  It can come from a variety of sources: .cer file, .pfx file, PEM files,
#  an in-memory representation, or directly from a Windows
#  registry-based certificate store.

#  This example will load a certificate object from a .cer file.
#  Note: Only the public-key is required to encrypt.  (Decryption
#  requires a private key.)

cert = Chilkat::CkCert.new()
success = cert.LoadFromFile("myCert.cer")
if (success == false)
    print cert.lastErrorText() + "\n";
    exit
end

#  Encrypt the MIME:
success = mime.Encrypt(cert)
if (success == false)
    print mime.lastErrorText() + "\n";
    exit
end

#  Display the MIME:
print mime.getMime() + "\n";

#  The resulting S/MIME looks something like this:
#  
abc: 123
Content-Disposition: attachment; filename="smime.p7m"
