Chilkat2-Python

Add a PFX Source to MailMan from BinData

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.

# Note: The path "qa_data/certs/decryption.pfx" is a relative local filesystem path,
# relative to the current working directory of the running application.

# Note: Explicitly connecting/authenticating is optional.  Chilkat MailMan automatically
# connects and authenticates -- using the property settings above -- whenever a server
# operation requires it.  Calling the explicit connect/authenticate methods can still be
# helpful to determine whether a failure occurs while connecting or while authenticating.
