Add a PFX Source File for S/MIME Decryption

Demonstrates the Chilkat Imap.AddPfxSourceFile method, which adds a PFX file as a source of certificates and private keys for S/MIME processing. The first argument is the PFX file path and the second is its password. Call it once for each additional source.

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

Background: This is the file-based form of AddPfxSourceBd. Registering the private keys needed to decrypt S/MIME mail lets Chilkat decrypt messages transparently during fetch. Add several sources if recipients' keys are spread across multiple PFX files. On Windows and macOS the system stores (and Keychain) are searched automatically in addition to the sources you add.
