## What it is
MesaLink is a memory-safe TLS library written in Rust that provides an OpenSSL-compatible C API, implemented on top of rustls, webpki, and ring. It lets existing C/C++ applications linked against OpenSSL switch to a Rust-based TLS backend with minimal code changes.

## Use cases
- replace OpenSSL with a memory-safe TLS implementation
- add TLS support to a C/C++ application without OpenSSL
- use rustls from C code via an OpenSSL-compatible API
- secure curl or RPC frameworks with a Rust TLS backend
- reduce memory-safety vulnerabilities in TLS termination

## When to choose
- you maintain C/C++ software that links against OpenSSL and want memory-safe TLS
- you want rustls's security guarantees without rewriting your application in Rust

## When to avoid
- you need a actively maintained project - the last release was in 2021 and development has stalled
- you are writing pure Rust and can use rustls directly
- you need the full OpenSSL feature set, as only a subset of the API is implemented

## Facets
- artifact type: library
- maturity: abandoned
- function: security, cryptography, http-server
- domain: security, networking, developer-tools
- platform: windows, rust, cpp, cross-platform
- tags: tls, openssl-compatibility, rustls, memory-safety, ssl, linux, macos
