Have you had experience working with JKS key storage format?

JKS (Java KeyStore) is a standard format for storing cryptographic keys and certificates in Java. It is used for securely storing private keys, public keys, and certificates, which are used, for example, in SSL/TLS connections.

Working with JKS is usually done through the KeyStore class in Java. Example of loading a JKS file:

KeyStore keyStore = KeyStore.getInstance("JKS");
try (InputStream is = new FileInputStream("keystore.jks")) {
    keyStore.load(is, "password".toCharArray());
}

// Getting a key
Key key = keyStore.getKey("alias", "password".toCharArray());
