I've installed x.509 self-signed certificate into local machine TRCA store on Windows 7 SP1 with all updates applied. In "certmgr" I've seen that "this certificate has an invalid digital signature". Certificate signature algorithm is "sha1ECDSA" wich must be supported by CNG on NT 6.x. Why I've got a problem with that?

Thanks for feedback. Look at this certificate for exapmle: http://jmrtd.org/csca/de.cer. It's provoke the same issue.

Can you export the certificate from TRCA? Please upload the file to a location that I'm able to access, I will download it and do testing on my side.
