Load Identities from PEM Text

See more PFX/P12 Examples

Demonstrates Pfx.LoadPem, which loads one or more certificate/private-key identities from PEM-formatted text and builds the contents of the Pfx 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.
