Hello all,

I have certificate and I have set him my CSP ( by setting
CERT_KEY_PROV_INFO),
so my CSP is called when I am using that certificate in IE (2SSL
communication).
In CSP I have implemented all functions to be wrappers to default CSP.
When I access web server using my certificate, next functions are
called
in this order :

1. CPAcquireContext
2. CPCreateHash
3. CPSetHashParam
4. CPSignHash
5. CPDestroyHash
6. CPReleaseContext

Everything is fine till CPSignHash is called by browser.
Function CPSignHash return error code 80090008 (Invalid algorithm
specified)
During the debug I have seen that CPCreateHash is called with
CALG_SSL3_SHAMD5
(0x00008008) as algorithm, I have forwarded all parameters to default
CSP.
Do I need to set any additional parameter in any of this functions to
make it
work correctly.

Code snippet is below the message.

Thanks in advance,
Ian
