Solution 2 – Set Cryptographic Provider to CSP

If you keep getting Windows Cryptographic Service Provider error, you might have to change your Cryptographic provider to CSP. This is relatively simple to do, and you can do it by following these steps:

  1. Open the SafeNet Authentication Client Tools. You can open it by going to its installation directory or by right clicking the SafeNet icon in system tray and selecting Tools from the menu.
  2. When SafeNet Authentication Client Tools opens click the ‘golden gear’ symbol in the top in order to open Advanced View.
  3. In Advanced View expand Tokens and navigate to the certificate you want to use for signing. They should be located under User certificates group.

After changing the Cryptographic provider, the problem should be completely resolved.


Solution 3 – Remove unwanted certificates

Sometimes Windows Cryptographic Service Provider error can appear due to certain certificates that are on your PC. However, you can fix the issue simply by finding and removing the unwanted certificates. You can remove unwanted certificates by doing the following:
