Constructor & Destructor Documentation

◆ KeyId() [1/2]

Botan::Stateful_Key_Index_Registry::KeyId::KeyId	(	std::string_view	algo_name,
		std::span< const uint8_t >	algo_params,
		uint64_t	max_operations,
		std::span< const uint8_t >	key_material_1,
		std::span< const uint8_t >	key_material_2 )

Create a KeyId for some kind of key material

Parameters

algo_name	Algorithm name (ex "XMSS", "HSS-LMS")
algo_params	Encoding of the algorithm parameters
max_operations	Maximum number of operations the key supports. This must be derived from algo_params; equal identities must have equal maximums.
key_material_1	First part of key identifying material
key_material_2	Second part of key identifying material (can be omitted)
