require 'chilkat'

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

mime = Chilkat::CkMime.new()

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

cert = Chilkat::CkCert.new()
success = cert.LoadFromFile("qa_data/pem/mf_public_rsa.pem")
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 like this:

# Content-Type: application/x-pkcs7-mime; name="smime.p7m"; smime-type="enveloped-data"
# abc: 123
# Content-Disposition: attachment; filename="smime.p7m"
# Content-Transfer-Encoding: base64
