Add a PFX Source to MailMan from BinData

See more POP3 Examples

Demonstrates the Chilkat MailMan.AddPfxSourceBd method, which adds a PFX/PKCS#12 certificate store to the MailMan object's internal list of sources used for locating certificates and private keys. The first argument is a BinData containing the PFX bytes and the second is the PFX password. This example loads a PFX into a BinData, registers it, and fetches a message Chilkat can decrypt.

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 HTTPS download — letting you supply the certificate and private key without first writing sensitive key material to disk.
