NCryptIsAlgSupported with Key storage provider (KSP)
NCryptIsAlgSupported function determines if Key Storage Provider (KSP) supports a specific cryptographic algorithm.
Parameters
-
hProvider[in] -
The handle of the key storage provider. Use NCryptOpenStorageProvider to get the handle.
-
pszAlgId[in] -
A pointer to a null-terminated Unicode string that contains the identifier of the cryptographic algorithm to create the key. AWS CloudHSM Key Storage Provider (KSP) supports the following algorithms:
