Load a PFX from BinData

See more PFX/P12 Examples

Demonstrates Pfx.LoadPfxBd, which loads a PFX / PKCS#12 container from the bytes held in a BinData object.

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.
