Add a PFX Source File for S/MIME Decryption

See more IMAP Examples

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.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
