BCryptAlgorithm Class Reference

#include <BCryptAlgorithm.h>

Detailed Description

RAII wrapper for BCRYPT_ALG_HANDLE.

Manages the lifecycle of a BCrypt algorithm provider handle. Automatically opens the algorithm provider on construction and closes it on destruction. Move-only type: supports move semantics but prevents copying to avoid double-release.

Public Member Functions
	BCryptAlgorithm (LPCWSTR algorithmName, ULONG flags=0)
	Opens a BCrypt algorithm provider.
	BCryptAlgorithm (BCryptAlgorithm &&other) noexcept
	Move constructor.
	~BCryptAlgorithm ()
	Closes the algorithm provider handle.
BCryptAlgorithm &	operator= (BCryptAlgorithm &&other) noexcept
	Move assignment operator.
BCRYPT_ALG_HANDLE	get () const
	Gets the underlying BCRYPT_ALG_HANDLE.

Constructor & Destructor Documentation

BCryptAlgorithm() [1/2]

tenduke::crypto::win::cng::BCryptAlgorithm::BCryptAlgorithm ( LPCWSTR algorithmName, ULONG flags = 0 )

explicit

Opens a BCrypt algorithm provider.

Parameters

algorithmName	the name of the algorithm (e.g., BCRYPT_AES_ALGORITHM)
flags	optional flags for BCryptOpenAlgorithmProvider (e.g., BCRYPT_ALG_HANDLE_HMAC_FLAG)

Exceptions

CryptoException

if the algorithm provider cannot be opened

BCryptAlgorithm() [2/2]

tenduke::crypto::win::cng::BCryptAlgorithm::BCryptAlgorithm ( BCryptAlgorithm && other )

noexcept

Move constructor.

Transfers ownership of the handle.
