ComputeSignature Exception about gostcryptography HOT 8 CLOSED

Issue resolved by reinstalling CryptoPro, possibly got broken by VipNet Client update (both on the same machine)

from gostcryptography.

The only difference is CryptoPro CSP version, exception happens on machine with CSP 5.0

from gostcryptography.

Hello! Thank you for the feedback. Which .NET version do you use?

from gostcryptography.

4.5.2 and above

from gostcryptography.

I can suggest the next options:

• verify that the certificate is available for the app user
• ensure that the app user use the correct certificate to sign (better to use Thumbprint to search)

from gostcryptography.

Certificate that is used is the only one in the user storage, code checked line by line, there aren't anything missing that would prevent it from working at a glance, exception is somewhere deep in the library, i don't even understand what it means and where to begin to look to fix it

from gostcryptography.

Issue is rather critical, as this is used in signing and sending important data, i need to get it working by april

from gostcryptography.

Could you create a test that reproduces the issue? Also specify .NET and CSP versions, the certificate properties. As I understand CryptoPro CSP 4.* works well?
