Read JCEKS Containing Secret Keys

See more Java KeyStore (JKS) Examples

Demonstrates how to read a JCEKS keystore file containing symmetric secret keys (for AES, Blowfish, HMAC SHA25, ChaCha, etc.)

This example uses the jceks sample file that you may download from Sample JCEKS with Secret Keys

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

This example requires Chilkat v9.5.0.66 or greater.
