Interface SymmetricKeyAlgorithmNegotiator


public interface SymmetricKeyAlgorithmNegotiator
Interface for symmetric key algorithm negotiation.
  • Method Details

    • negotiate

      Negotiate a symmetric encryption algorithm. If the override is non-null, it will be returned instead of performing an actual negotiation. Otherwise, the list of ordered sets containing the preferences of different recipient keys will be used to determine a suitable symmetric encryption algorithm.
      Parameters:
      policy - algorithm policy
      override - algorithm override (if not null, return this)
      keyPreferences - list of preferences per key
      Returns:
      negotiated algorithm
    • byPopularity

      static SymmetricKeyAlgorithmNegotiator byPopularity()
      Return an instance that negotiates a SymmetricKeyAlgorithm by selecting the most popular acceptable algorithm from the list of preferences. This negotiator has the best chances to select an algorithm which is understood by all recipients.
      Returns:
      negotiator that selects by popularity
