We want to develop custom Cryptographic Service Provider (CSP). For this we are referring following link
https://msdn.microsoft.com/en-us/library/windows/desktop/aa380245%28v=vs.85%29.aspx
From the documents, we understood that following cryptographic functions need to be implemented for custom CSP.
- CPAcquireContext
- CPCreateHAsh
- CPDecrypt etc. as mentioned in the following link
https://msdn.microsoft.com/en-us/library/ms925441.aspx
According to this link, CPAcquireContext function takes following arguments
BOOL CPAcquireContext(
_Out_ HCRYPTPROV *phProv,
_In_ CHAR *pszContainer,
_In_ DWORD dwFlags,
_In_ PVTableProvStruc pVTable
);
but we did not find any further information(like what need to do with these arguments and how to fill HCRYPTPROV structure) about the implementation of CPAcquireContext or any other entry points mentioned in the link.
Is there any other document which explain this portion in detail? can anyone give further assistance in developing these functions.
