(VB.NET) Load a JWK Set into a JCEKS (Convert JWK Set to JCEKS)

Demonstrates how to convert JSON Web Key Sets to JCEKS format.

This example uses the JWK sample files that you may download from Sample JWK Sets

This example requires Chilkat v9.5.0.66 or greater.

'  IMPORTANT: This example requires Chilkat v9.5.0.66 or greater.

'  This example requires the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

Dim jceks As New Chilkat.JavaKeyStore
