CRC32c is used in SCTP for integrity checking, and the third_party/crc32c library (https://github.com/google/crc32c) which has been optimized for SSE42 and arm64 and has a much faster fallback implementation for other architectures.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
