: Windows may cache the binding handle internally. For example, when using the software KSP, it binds to the KeyIso (CNG Key Isolation) service. If that service restarts, existing handles may become invalid. If that service restarts, existing handles may become

: By using this function, an application can support specialized hardware (like a TPM or a smart card) simply by changing the provider string, without requiring a rewrite of the cryptographic logic. status = NCryptCreatePersistedKey(hProvider
