Learn how Opportunistic Encryption allows clients to use traditionally insecure protocols over secure channels like TLS.

What is Opportunistic Encryption?

Opportunistic Encryption allows browsers to access HTTP URIs over an encrypted TLS channel.

It's not a replacement for HTTPS (and will not show the lock icon in browsers), but Opportunistic Encryption does provide a more secure connection.

Use HTTPS when both strong encryption and authentication are required.

Enable Opportunistic Encryption

To set up Opportunistic Encryption:

1. Log into your Cloudflare account and go to a specific domain.

2. Go to SSL/TLS.

3. For Opportunistic Encryption, select On.
