(MFC) Convert JCEKS to JWK Set (JSON Web Key Set)

Demonstrates how to read a JCEKS keystore file containing a mixture of key types (ECC key and symmetric secret key), and converts to a JWK Set (JSON Web Key Set).

This example uses the jceks sample file that you may download from Sample JCEKS with Multiple Key Types (ECC Key and Secret Key)

The file password is "mixed". The password for each key contained in the JCEKS is "password".

This example requires Chilkat v9.5.0.66 or greater.
