Set a PFX Safe-Bag Attribute

See more PFX/P12 Examples

Demonstrates Pfx.SetSafeBagAttr, which sets a safe-bag attribute on a private key or certificate inside the PFX.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.
