Add a PFX Source from BinData

Demonstrates the Chilkat Email.AddPfxSourceBd method, which adds PFX data held in a BinData object to the list of certificate and private-key sources used during decryption or signing. The second argument is the PFX password. Call it before obtaining the encrypted email so Chilkat can decrypt it automatically. This example loads a PFX into a BinData, adds it, and then loads an encrypted email.

Background: This is the in-memory (BinData) counterpart to AddPfxSourceFile. It is the right choice when the PFX bytes come from somewhere other than a file — a database, a secrets manager, or an HTTP download — letting you supply the certificate and private key without first writing them to disk (which is preferable for sensitive key material).
