Provide a Certificate Vault to an Email

Demonstrates the Chilkat Email.UseCertVault method, which adds an XML certificate vault to the email's internal certificate and private-key lookup sources for encryption, decryption, signing, and verification. This example builds a vault from a PFX and attaches it to the email.

Background: A certificate vault is a portable, in-memory store of certificates and private keys. Instead of wiring up each certificate individually for every operation, you load your credentials into one XmlCertVault and hand it to the email; Chilkat then draws on it automatically whenever it needs a key — to decrypt an incoming message, sign an outgoing one, or verify a signature. This is especially convenient on platforms without an OS certificate store.
