Hi All, We currently have a WPF application built on .Net framework 4.7. This application acts as an HTTPS client. We need to validate the below parameters against a valid Https certificate: The signature The stored certificates The validity against Certificate Revocation List (CRL) The validity date The IP address checking on Subject Alternative Name Can anyone please help me in validating these specific parameters alone. Any help is appreciated!! Thank you!!

@S Abijith , for the signature Validating, you can refer to the link C# Validate Signature. For the date, you could have a look about Check SSL-Certifacte expiration date without authorization. Currently I only find the two parameters. You could try the code to see if it can be validated successfully. I will go on searching other specific parameters.
