Find a PFX Certificate by localKeyId

See more PFX/P12 Examples

Demonstrates Pfx.CertByLocalKeyId, which searches for a certificate whose certificate-bag localKeyId attribute matches a given value and copies it into a Cert 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.
