Read a PFX Safe-Bag Attribute

See more PFX/P12 Examples

Demonstrates Pfx.GetSafeBagAttr, which reads a recognized safe-bag attribute from 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.

Background. A safe-bag attribute is metadata attached to an item inside a PKCS#12/PFX container; it does not change the certificate or private-key material. Recognized attributes include friendlyName, keyContainerName, keyName, and localKeyId.
