According to technical discussions, NCryptOpenStorageProvider might cache handles for performance reasons, specifically when utilizing MS_KEY_STORAGE_PROVIDER .

Mastering CNG: A Deep Dive into NCryptOpenStorageProvider and Modern Cryptography in Windows
The following logical flow outlines a secure end-to-end key implementation in C++: Step 1: Initialize the Provider Context ncryptopenstorageprovider new
: A pointer to a variable that receives the provider handle. This handle must eventually be released using NCryptFreeObject .
The use of NcryptOpenStorageProvider offers several benefits, including:
To get the most out of NCryptOpenStorageProvider , developers should follow best practices, such as: To create or open a key, you must
The NCryptOpenStorageProvider function, found in ncrypt.h , is a foundational CNG API that loads and initializes a specific CNG Key Storage Provider. A KSP is a software or hardware module that handles the lifecycle of cryptographic keys (generation, storage, usage, and destruction). Common providers include:
: You can specify a particular provider by name, such as MS_KEY_STORAGE_PROVIDER (software-based) or MS_PLATFORM_CRYPTO_PROVIDER (TPM-based).
To create or open a key, you must first obtain a provider handle. NCryptOpenStorageProvider function (ncrypt.h) - Win32 apps To create or open a key
In legacy models, yes. LUKS or dm-crypt could add 15-20% latency. However, the NcryptOpenStorageProvider leverages .
The function supports Windows Vista and Windows Server 2008 as its minimum supported clients.
