      • ecmaId

        public final int ecmaId
        the id used for the BIFF encryption info header

      • ecmaString

        public final String ecmaString
        the id used for OOXML encryption info header

      • hashSize

        public final int hashSize

    • Method Detail

      • values

        public static HashAlgorithm[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (HashAlgorithm c : HashAlgorithm.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static HashAlgorithm valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null

      • fromEcmaId

        public static HashAlgorithm fromEcmaId​(int ecmaId)
