Facebook turns Fizz - a library that enhances security protocols - into open source

Facebook has decided to turn Fizz - a library of security and performance-related documents - into open source, helping developers implement the newly released TLS 1.3 protocol.

Since last month, Chrome has started marking websites that do not use HTTPS as 'Not Secure' to force webmasters to switch to HTTPS, creating a safer online world.TLS 1.3 is the most secure new encryption protocol of TLS, succeeding SSL, used to encrypt data transferred between server and client to prevent data theft.

To ensure the safety of Internet traffic, TLS 1.3 offers a number of new features such as handshake encrypted messages to keep certificates secure, redesign how to create security keys and connections. 0-RTT, help send requests faster than TLS 1.2.

Written in C ++ 14, Fizz is a reliable TLS library that supports all popular handshake modes, powerful encryption algorithms, and optimized operations for secure data transfer at a faster rate than 10. %

'Encryption and decryption are not copyable, closely associated with other parts of architecture and optimization, Fizz has helped reduce memory and CPU consumption significantly ', Facebook said in its statement. This library is open source.

A Facebook TLS library is shared with the community

Facebook replaced the old Zero protocol with Fizz, now responsible for securing billions of billions of connections every day on Facebook.The social networking giant said that they had 'deployed Fizz and TLS 1.3 globally on mobile applications, Proxygen, internal services, load balancing and both QUIC and mvfst libraries.More than 50% of our network traffic is secured by TLS 1.3 '.

By bringing Fizz to the open source world, Facebook wants to share its technology with the world, helping promote the development of the latest TLS 1.3 protocol in the world, making applications and services not only fast. but also safer.

Fizz is available on GitHub, you can access its source code if you wish.
