Serialize a PFX to an Encoded String

See more PFX/P12 Examples

Demonstrates Pfx.ToEncodedString, which serializes the current PFX contents and returns the PKCS#12 bytes encoded as text using a named encoding.

-- Important: See this note about string length limitations for strings returned by sp_OAMethod calls.
