Manage Self-Signed Certificates

Instead of obtaining a digital certificate from a CA, you can generate and sign your own digital certificate. However, a self-signed certificate triggers a warning from most browsers because it provides no protection against identity theft of the server. (The following figure shows an image of a browser security alert.)

There can be three reasons why a security alert is generated for a security certificate:

•The security certificate was issued by a company you have not chosen to trust.

•The date of the security certificate is invalid.

•The name on the security certificate is invalid or does not match the name of the site.

When a security alert is generated, the user can decide whether to trust the host.
