    • Method Detail

      • getInstance

        public static ExtendedKeyUsage getInstance​(ASN1TaggedObject obj,
                                           boolean explicit)
        Return an ExtendedKeyUsage from the passed in tagged object.
        Parameters:
        obj - the tagged object containing the ExtendedKeyUsage
        explicit - true if the tagged object should be interpreted as explicitly tagged, false if implicit.
        Returns:
        the ExtendedKeyUsage contained.

      • getInstance

        public static ExtendedKeyUsage getInstance​(java.lang.Object obj)
        Return an ExtendedKeyUsage from the passed in object.
        Parameters:
        obj - an ExtendedKeyUsage, some form or encoding of one, or null.
        Returns:
        an ExtendedKeyUsage object, or null if null is passed in.

      • fromExtensions

        public static ExtendedKeyUsage fromExtensions​(Extensions extensions)
        Retrieve an ExtendedKeyUsage for a passed in Extensions object, if present.
        Parameters:
        extensions - the extensions object to be examined.
        Returns:
        the ExtendedKeyUsage, null if the extension is not present.

      • hasKeyPurposeId

        public boolean hasKeyPurposeId​(KeyPurposeId keyPurposeId)
        Return true if this ExtendedKeyUsage object contains the passed in keyPurposeId.
        Parameters:
        keyPurposeId - the KeyPurposeId of interest.
        Returns:
        true if the keyPurposeId is present, false otherwise.
