It gives native programs a fast way to answer questions that matter for cookies, certificates, domain display, and site grouping. ### 项目历史 The library was created by Tim Ruehsen from libmget cookie code on 2014-03-19, according to the source changelog, and the public GitHub repository was created on 2014-03-20. The README describes libpsl as a C library that handles the Public Suffix List with built-in PSL data, file-loaded PSL data, DAFSA compression, thread safety, and IDNA support. The Public Suffix List itself is a cross-vendor initiative maintained by Mozilla volunteers and registry submissions. libpsl packages that ecosystem for C consumers rather than trying to define suffix policy itself. ### 采用历史 libpsl's adoption comes from web-client and network-client needs: software must avoid supercookies, reject overbroad certificate or domain assumptions, and group sites by registrable domain. The Public Suffix List page names browsers, Qt, crawler libraries, certificate-authority workflows, and security tooling as users of PSL data. Package managers carry libpsl because many lower-level network tools need PSL behavior without embedding their own parser. Homebrew, Debian-family systems, Fedora, MacPorts, Nix, Arch, Alpine, and openSUSE all appear in the package metadata for this batch. ### 使用方式 Developers use libpsl through the C API to test whether a domain is a public suffix, verify cookie-domain acceptability, find public or private domain portions, or load updated PSL data. The package also ships the `psl` command and `psl-make-dafsa` for command-line inspection and compressed list generation. ### 为什么软件包爱好者会关心 libpsl is package-nerd significant because it is tiny infrastructure with security consequences. A stale or missing PSL layer can allow cookie scoping mistakes or bad domain-boundary assumptions, while a shared library lets distributions update the logic and data path centrally. Its build and packaging details are also unusually nerdy: the README separates libpsl releases from PSL data updates, supports both autotools and Meson, and uses DAFSA compression to shrink lookup data for fast native access. ### 时间线 -
