Add a PFX File 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.

AddPfxSourceFile registers a PFX/P12 file as a source of certificates and private keys used by subsequent decryption operations.

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.

Use ChilkatAx-win32.pkg
