    • getPrivateKeys

      public List<PrivateKey> getPrivateKeys()
      Return a list of the component private keys making up this composite.
      Returns:
      an immutable list of private keys.

    • getProviders

      public List<Provider> getProviders()
      Return a list of the providers supporting the component private keys.
      Returns:
      an immutable list of Provider objects.

    • getAlgorithm

      public String getAlgorithm()
      Return the name the composite algorithm this key belongs to is registered under, or null if the key's algorithm is not one of the composite signature or composite KEM parameter sets (the legacy generic composite key OIDs have no registered name of their own).
      Specified by:
      getAlgorithm in interface Key
      Returns:
      the composite algorithm name, e.g. "MLDSA44-Ed25519-SHA512" or "MLKEM768-X25519-SHA3-256".
