## What it is
BoringSSL is Google's fork of OpenSSL, serving as the TLS/SSL library in Chrome, Chromium, and Android. It is open source but explicitly not intended for general third-party use, with no API or ABI stability guarantees.

## Use cases
- implement TLS in a Chromium-based browser
- need an SSL library for an Android system component
- port OpenSSL-based code to Google's TLS stack
- fuzz and audit a TLS implementation for security research
- vendor a TLS library into a project that tracks upstream changes

## When to choose
- you are Google or a project already integrated with BoringSSL
- you can vendor and update your own copy of the library
- you need the exact TLS stack used by Chrome/Android

## When to avoid
- you want a general-purpose TLS library with stable APIs
- you are a third party starting a new project (use OpenSSL, LibreSSL, or rustls instead)
- you rely on ABI stability across versions

## Facets
- artifact type: library
- maturity: active
- function: cryptography, security, http-server
- domain: security, developer-tools, web-development
- platform: cpp, c, cross-platform
- tags: tls, ssl, openssl-fork, google, chrome, no-api-stability, android
