Add a PFX File as a Decryption Source
See more MIME Examples
Loads a CMS/PKCS #7 encrypted S/MIME message and decrypts it back to the original MIME content.
AddPfxSourceFile registers a PFX/P12 file as a source of certificates and private keys used by subsequent decryption operations.
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. Multiple PFX sources can be added so that a single Mime object is able to decrypt messages addressed to any of several identities. Chilkat chooses the matching key at decryption time.
