WinCrypt API - RSA

Recommended Posts

deepzero

Hi there,

I was trying to implement a simple RSA signature verification scheme.

Fortunately, Microsoft gives an example of using the crypto apis, which does precisely that:


/>http://msdn.microsoft.com/en-us/library/aa382371%28v=vs.85%29.aspx

This looks good, but doesnt actually work.

The second api call, CryptGetUserKey() fails. GetLastError() returns "0x8009000d", which is not defined to my knowledge.

am i missing something...?

The error code is:

NTE_NO_KEY

The key requested by the dwKeySpec parameter does not exist.

It simply means there is no key in your container. Take a look at this sample:
