Facebook to Roll Out Fizz Library

This library accelerates the deployment of TLS 1.3 over the Internet
08 August 2018   776

Facebook introduced a library called Fizz, specially released for the recent update of TLS under the number 1.3. Fizz is a library that accelerates the deployment of TLS 1.3 over the Internet and increases the speed and security of applications and services.


  • Asynchronous I / O supported by default
  • Improved collection / spread of input / output required from copies of data.
  • Delays and loadings of service processors are reduced, which process trillions of requests per day.
  • Data is divided into "pieces" and encrypted.

Fizz and TLS 1.3 are globally applied in mobile Proxygen applications, in load balancers, in internal services and the QUIC library, mvfst. Currently, Facebook protects more than 50% of its traffic using Transport Layer Security. Applications that use Fizz perform fewer memory and copy allocations.

In TLS 1.3, the concept of "early data" (zero data, or data from 0-RTT) was introduced, which helped to reduce the waiting time. According to ITEF, it does this without waiting for the TLS acknowledgment. However, this concept can be unsafe, so Fizz includes an API that helps to get rid of shortcomings.

In addition, Fizz provides two types of APIs that can handle the rejection of "early data": transparently or allowing the application to modify the information sent repeatedly.

Node.js v12.0.0 to be Rolled Out

It has giant list of updates, improvements and changes
24 April 2019   559

The release of Node.js 12.0.0, a platform for executing network applications in JavaScript, is available. Node.js 12.0 refers to branches with a long period of support, but this status will be assigned only in October, after stabilization. Updates for LTS branches are issued for 3 years. Support for the last LTS branch of Node.js 10.0 will last until April 2021, and the year before last LTS-branch 8.0 until January 2020. Support for the intermediate branch Node.js 11.0 will be discontinued in June 2019. The lifetime of the LTS branch 6.0 will end on April 30.

These are some of the large list of updates and new staff:

  • V8 engine was updated to version 7.4 with support for asynchronous stack traces, increasing await performance, parsing JavaScript and calls when the actual and declared number of arguments does not match;
  • TLS 1.3 is now¬†supported in the tls module and TLS 1.0 / 1.1 is shutdown by default;
  • Enhancing protection and checks on the size of allocated memory in the Buffer class;
