Class CryptoUtils

java.lang.Object

pt.unl.fct.di.novasys.babel2.utils.CryptoUtils

public final class CryptoUtils
extends Object

Cryptographic utility methods used by the Babel framework for node key generation and identity management.

By default, Babel uses Ed25519 public key cryptography for high performance and strong security guarantees across distributed nodes.
