WebAs explained in answers to this question here, the raw private key is encrypted in the keystore file's "ciphertext", with the given algorithm and parameters (e.g. in our example, it's aes-128-ctr and an initial vector). WebThis class represents a factory for secret keys. Key factories are used to convert keys (opaque cryptographic keys of type Key) into key specifications (transparent representations of the underlying key material), and vice versa. Secret key factories operate only on secret (symmetric) keys.
