        Returns:
        the number of times the key can be used before it is exhausted.

      • extractKeyShard

        XMSSPrivateKey extractKeyShard​(int usageCount)
        Return a key representing a shard of the key space that can be used usageCount times.

        Note: this will use the range [index...index + usageCount) for the current key.

        Parameters:
        usageCount - the number of usages the key should have.
        Returns:
        a key based on the current key that can be used usageCount times.
