Hi,

I am trying to use CryptoPro COM interface (https://docs.cryptopro.ru/cades/reference/cadescom). What I need to do is sign the data. I am trying to do that in exactly the same way as in the example provided ( https://docs.cryptopro.r...s/cadescomsamplesigndata ).
The problem that it fails on the last step which is signing the data. It fails with following error: "System.Runtime.InteropServices.COMException: 'A certificate chain could not be built to a trusted root authority.'". Are you able to tell me how to fix this ?
