    • Method Detail

      • notBlacklisted

        public static Predicate<Algorithm> notBlacklisted()
        A predicate that can be combined with other predicates to ensure that the resulting Algorithm is not blacklisted.
        Returns:
        a predicate

      • fromJcaName

        public static Predicate<Algorithm> fromJcaName​(String jcaName)
        Predicate for finding an algorithm based on its JCA name.
        Parameters:
        the - JCA name
        Returns:
        a predicate

      • fromType

        public static Predicate<Algorithm> fromType​(AlgorithmType type)
        Predicate for finding an algorithm based on its type.
        Parameters:
        type - the algorithm type
        Returns:
        a predicate

      • fromKeyType

        public static Predicate<Algorithm> fromKeyType​(String keyType)
        Predicate for finding an algorithm based on its key type.
        Parameters:
        keyType - the key type
        Returns:
        a predicate

      • fromAlgorithmIdentifier

        public static Predicate<Algorithm> fromAlgorithmIdentifier​(org.bouncycastle.asn1.x509.AlgorithmIdentifier algorithmIdentifier)
        Predicate for finding an algorithm based on its AlgorithmIdentifier.
        Parameters:
        algorithmIdentifier - the algorithm identifier
        Returns:
        a predicate

      • fromAlgorithmIdentifierRelaxed

        public static Predicate<Algorithm> fromAlgorithmIdentifierRelaxed​(org.bouncycastle.asn1.x509.AlgorithmIdentifier algorithmIdentifier)
        Predicate for finding an algorithm based on its AlgorithmIdentifier. The method implementation is "relaxed" which means that if no parameters are supplied in the algorithmIdentifier the comparison of parameters will be excluded. This covers for the case when the special NULL param is used.

        Also, for RSA-PSS, we compare only the digest part of the parameters.

        Parameters:
        algorithmIdentifier - the algorithm identifier
        Returns:
        a predicate
