Is there a way to check if the SSL digital certificate is valid without installing on the web server?
问题 Are there any tools or mechanism(s) which can help validate a CA issued SSL certificate before installing it on the target web server? 回答1: Yes, you can use openssl to create a test server for your certificate with the s_server command. This creates a minimal SSL/TLS server that responds to HTTP requests on port 8080: openssl s_server -accept 8080 -www -cert yourcert.pem -key yourcert.key -CAfile chain.pem yourcert.pem is the X.509 certificate, yourcert.key is your private key and chain.pem
