error:0308010C:digital envelope routines::unsupported when running client application
This error usually occurs when you try to use digital signature or encryption features in a client application that does not support these features. Make sure that you are using the correct version of the digital signature and encryption software, and make sure that the client application has access to the necessary libraries and dependencies. It’s also worth making sure that you use the correct parameters when calling digital signature and encryption functions, and that your keys and certificates are valid and compliant. If all of these conditions are met, you may need to contact support or software developers for additional help with this problem.
