Use an XML Certificate Vault with IMAP

Demonstrates the Chilkat Imap.UseCertVault method, which associates an XmlCertVault with the Imap object as a source of certificates and private keys for S/MIME operations. The only argument is the vault. Only one vault is associated at a time.

Note: The certificate path is relative to the application's current working directory. Supply the path to your own certificate file.

Background: An XmlCertVault is a portable container that can hold multiple certificates and keys in a single (optionally password-protected) XML file. It is a convenient way to ship the exact set of credentials an application needs without depending on the operating system's certificate stores. Associating a vault makes all of its contents available for S/MIME decryption and signature verification.
