(Perl) Export Private Keys from Java KeyStore to JWK Set

Demonstrates how to export the private keys from a Java KeyStore to a JWK Set. Each private key alias is exported to the "kid" parameter.

Note: This example requires Chilkat v9.5.0.66 or greater.

# to verify the keyed digest that is found at the very end of the keystore.
# It verifies that the keystore has not been modified.
