Explain Encryption modes available in Cloudflare

Cloudflare, a popular content delivery network, provides four encryption modes to secure communication between clients and servers. This article will explore the different encryption modes available in Cloudflare. Cloudflare’s SSL/TLS encryption mode helps determine how to validate the SSL certificate in your origin server. SSL/TLS is a protocol that provides secure communication over the internet.

SSL/TLS Encryption Modes:

Flexible SSL: This mode encrypts the connection between the client and Cloudflare using SSL/TLS, but the connection between Cloudflare and the origin server is unencrypted. This mode is suitable for websites that cannot handle SSL/TLS on their origin servers.

Full SSL: This mode encrypts the connection between the client and Cloudflare using SSL/TLS, and the connection between Cloudflare and the origin server is unencrypted. This mode is suitable for websites without end-to-end encryption or backend systems that cannot handle SSL/TLS.

 

Full SSL (Strict): This mode encrypts the connection between the client and Cloudflare using SSL/TLS, and the connection between Cloudflare and the origin server is also encrypted using SSL/TLS. This mode provides end-to-end encryption and is suitable for websites that require maximum security.

Off(Not Secure): HTTPS requests are redirected to plaintext HTTP when your encryption mode is Off (not recommended). It is not recommended to set the encryption mode to Off.

Overall, Cloudflare's SSL/TLS encryption modes provide a range of options to suit different security needs and compatibility requirements. It is important to choose the appropriate mode based on the level of security required and the capabilities of the client and server systems.
