AddDetachedSignaturePk

See more MIME Examples

Demonstrates how to add a detached signature using a certifcate and it's corresponding private key. The easiest way of doing it is when both the certificate and private key are contained together within a PFX (.pfx or .p12) file. This example demonstrates how to use the certificate and its corresponding private key when they are stored in separate files -- a .cer for the certificate, and a .pem for the private key.
