Add PFX Bytes as a Decryption Source

See more MIME Examples

Loads a CMS/PKCS #7 encrypted S/MIME message and decrypts it back to the original MIME content.

AddPfxSourceBd registers PFX/P12 bytes held in a BinData as a source of certificates and private keys for later decryption.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.
