Interface HashAlgorithmNegotiator

public interface HashAlgorithmNegotiator
Interface for a class that negotiates HashAlgorithms. You can provide your own implementation using custom logic by implementing the negotiateHashAlgorithm(Set) method.

  • Method Details

    • negotiateHashAlgorithm

      HashAlgorithm negotiateHashAlgorithm(Set<HashAlgorithm> orderedHashAlgorithmPreferencesSet)
      Pick one HashAlgorithm from the ordered set of acceptable algorithms.
      Parameters:
      orderedHashAlgorithmPreferencesSet - hash algorithm preferences
      Returns:
      picked algorithms

    • negotiateSignatureHashAlgorithm

      static HashAlgorithmNegotiator negotiateSignatureHashAlgorithm(Policy policy)
      Return an instance that negotiates HashAlgorithms used for non-revocation signatures based on the given Policy.
      Parameters:
      policy - algorithm policy
      Returns:
      negotiator

    • negotiateRevocationSignatureAlgorithm

      static HashAlgorithmNegotiator negotiateRevocationSignatureAlgorithm(Policy policy)
      Return an instance that negotiates HashAlgorithms used for revocation signatures based on the given Policy.
      Parameters:
      policy - algorithm policy
      Returns:
      negotiator

    • negotiateByPolicy

      static HashAlgorithmNegotiator negotiateByPolicy(Policy.HashAlgorithmPolicy hashAlgorithmPolicy)
      Return an instance that negotiates HashAlgorithms based on the given Policy.HashAlgorithmPolicy.
      Parameters:
      hashAlgorithmPolicy - algorithm policy for hash algorithms
      Returns:
      negotiator
