mbed TLS mentions (1)

  • redbean: a single-file actually portable web server with Lua, HTTPS and SQLite
    Rebean is a single executable written in ANSI C that embeds Lua 5.4, MbedTLS and SQLite. The crazy thing about this is that it is a C binary that runs on six operating systems without any cross compiling thanks to leveraging Justine Tunney's cosmopolitan. Source: over 2 years ago
