Use an XmlCertVault for S/MIME Operations

See more MIME Examples

Loads a CMS/PKCS #7 encrypted S/MIME message and decrypts it back to the original MIME content.

UseCertVault sets an XmlCertVault as the single active source of certificates and private keys for S/MIME encryption, decryption, signing, and verification.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background. A certificate vault is a convenient container for one or more certificates and keys. Only one vault is active at a time; assigning a new vault replaces the previous one.
