Security protocols

Security protocols are used to communicate securely with sites where sensitive data, such as credit card information, is involved. The protocols most commonly used are SSL and TLS.

When you visit a site using security protocols, information displays in the badge to the left of the address field. For more about this, see the Fraud and Malware Protection topic. As a summary, a padlock displays for these sites and the domain name of the certificate is written. For sites with extended validation (EV), the name of the organization that registered the certificate is given. Click the security badge to see more information.

Enable or disable protocols

To enable or disable specific security protocols, from the menu, go to Opera > Preferences > Advanced > Security. Check or uncheck the protocols you want to enable or disable.

If you want to select ciphers to enable or disable, click the "Details" button.
