What should you do to fix a certificate error indicating your web server is not trusted?

To address a certificate error that indicates your web server is not trusted, installing a certificate from a trusted Certificate Authority (CA) is the most appropriate and effective action. Trusted CAs are organizations that validate the identity of the entity requesting a certificate and issue a digital certificate based on that verification. When a web server presents a certificate issued by a trusted CA, browsers and other clients can verify its authenticity, establishing a secure and trusted connection.

This trust is pivotal in online security, as it ensures users that they are communicating with the legitimate server rather than a potential attacker. On the contrary, certificates that are self-signed or from non-trusted sources will lead to warning messages in browsers, making users hesitant to proceed due to security concerns.

Other options like using a digital signature, generating a certificate request, or enabling Public Keys on your website can relate to certificate management or cryptographic practices, but they do not directly resolve the issue of a server being untrusted. A digital signature is used to sign data to ensure its origin and integrity, while generating a certificate request is a step in acquiring a certificate rather than fixing the issue itself. Enabling Public Keys does not address trust issues directly; it pertains to the cryptographic systems used in certificates. Because trust
