6. What types of certificates can be decoded?
The tool supports a variety of certificate types, including SSL/TLS certificates, code-signing certificates, and more. As long as the certificate is in a compatible format (PEM, DER, etc.), it can be decoded.
7. What should I do if the decoded information seems incorrect?
If the information appears inaccurate, double-check that the certificate you're entering is complete and in the correct format. You may also want to verify the certificate chain and check for any configuration issues.
