What libraries does curl use?

tyingq 4y ago
There's a list here: https://curl.se/docs/libs.html https://curl.se/docs/libs.html Edit: Summary: SSL/TLS: OpenSSL, mbed, GnuTLS, NSS TLS, wolfSSL decompression: zlib ldap: OpenLDAP LDAP support kerberos/spnego: heimdal, MIT Kerberos http2: nghttp2 async dns: c-ares idn domains: libidn scp/sftp: libssh2

  At least libproxy itself doesn't have any dependencies https://libproxy.github.io/libproxy/ https://libproxy.github.io/libproxy/ says "no external dependencies within libproxy core (libproxy plugins may have dependencies)"

    Interesting choice to have a set of FAQ in your docs without also providing answers to them. I suppose the term FAQ does sort of imply it is just the "questions".

    Sooo does it implement http ? Coz having lib to search for proxy (it supports few http auto config methods) with its own implementation of http to use in http library would be kinda silly

    The core doesn't have any dependencies, but it can support a bunch of different modules. Most notably is JavaScript to execute PAC files (WebKit, mozjs, etc.) For macOS it calls "JSEvaluateScript(this->jsctx, str, NULL, NULL, 1, NULL)". Obviously this kind of stuff is useful for some people, but yeah ... I'd be hesitant too; not because whether libproxy might be good or bad, but rather the nature of what it does (execute code).

  Note this isn't complete, it lists only 5 out of the 14 TLS libraries that cURL can be built for: https://daniel.haxx.se/blog/wp-content/uploads/2021/02/Screenshot_2021-02-09-curl-Project-status-dashboard.png https://daniel.haxx.se/blog/wp-content/uploads/2021/02/Scree... (source: https://daniel.haxx.se/blog/2021/02/09/curl-supports-rustls/ https://daniel.haxx.se/blog/2021/02/09/curl-supports-rustls/ ) Of course, it does include the two that cover 95+% of uses in OpenSSL and GnuTLS.

open-source curl, or corporate curl? Apple and MSFT build their own replacements for TLS and use those, others? part of a trend to replace and extend GPL software, and control critical network functions on their platforms ? but then, others seem to want to make TLS, too ? [ Windows native SSL/TLS, schannel ] [ Apple OS native SSL/TLS, secure-transport ] [ GNU TLS ] [ mbedtls, wolfssl, mesalink, bearssl, rust-tls, nss]
