Why does a verified certificate not automatically prove that a web server is appropriate for every use?
Answer
Verification shows that the certificate's signature can be checked against a trusted CA certificate, but suitability also depends on whether that CA is accepted, whether the certificate identity and details match the intended use, and whether it is within its validity period.
Explanation
### The concept
A certificate's signature helps establish that its contents have not been altered and that it was signed under a particular CA key. Verification is only one part of trust. A user must also trust the issuing authority and check whether the certificate's subject, validity period, and other details fit the intended server and use. A technically valid certificate may still be unsuitable for a particular connection.
### What a good answer covers
- Signature verification checks the certificate cryptographically.
- Trust depends on accepting the issuing CA.
- Identity and certificate details must suit the server and use.
- The validity period must be considered.
### Remember
A valid signature is evidence, not a complete suitability decision.
