It gives Unix and embedded developers a reusable CoAP parser, networking layer, examples, and client/server tools. ### Historique du projet The repository identifies libcoap as a C implementation of CoAP and carries copyright years beginning in 2010 for Olaf Bergmann and contributors. That places the project in the early CoAP implementation wave before the protocol was published as RFC 7252 in June 2014. As CoAP grew from a basic REST-like protocol for constrained devices into a family of RFC extensions, libcoap accumulated support for related specifications including group communication, observing resources, block-wise transfers, CoAP over TCP/TLS/WebSockets, OSCORE, hop limit, and echo/request-token processing. ### Historique d'adoption libcoap's adoption follows the embedded and IoT networking ecosystem rather than desktop application culture. Its README names hosted environments including Contiki-NG, Espressif ESP-IDF, LwIP, and RIOT-OS, which explains why package managers ship both library artifacts and tools such as `coap-client`, `coap-server`, and `coap-rd`. ### Modes d'utilisation Developers use libcoap to build CoAP clients, servers, resource directories, and test fixtures. Homebrew exposes separate OpenSSL-suffixed tools in addition to the base client, server, and resource-directory commands, making it useful both as a development library and a packet-level debugging utility. ### Pourquoi les passionnés de paquets s'y intéressent libcoap is package-nerd relevant because it is a small C library sitting at the boundary between standards work and actual device networks. It is the installable thing that turns RFC language about constrained REST into commands a maintainer can run against embedded boards, gateways, and simulators. ### Chronologie - 2010: Copyright range in the official repository begins for Olaf Bergmann and contributors. - 2014-06: RFC 7252 published CoAP as an Internet Standards Track protocol. - 2020s: Repository documents support for multiple CoAP extension RFCs and embedded environments. ### Related projects - Related projects and standards include RFC 7252 CoAP, Contiki-NG, RIOT-OS, LwIP, Espressif ESP-IDF, OSCORE, and the libcoap-minimal examples referenced by the project. ### Sources - - - - ## Notes de sécurité broad file, network, media, or database tool signal. - **Risque Geiger:** blue / moyen - broad file, network, media, or database tool signal ## Autres enregistrements de gestionnaires de paquets - Nix - libcoap: normalized package name match | nixpkgs package indexes: pkgs/by-name/li/libcoap/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - libcoap - 4.3.5b-r0: normalized package name match | Alpine Linux edge package indexes: libcoap from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | A CoAP (RFC 7252) implementation | https://libcoap.net/ - apk - libcoap-dev - 4.3.5b-r0: normalized package name match | Alpine Linux edge package indexes: libcoap-dev from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | A CoAP (RFC 7252) implementation (development files) | https://libcoap.net/ - apk - libcoap-doc - 4.3.5b-r0: normalized package name match | Alpine Linux edge package indexes: libcoap-doc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | A CoAP (RFC 7252) implementation (documentation) | https://libcoap.net/ - dnf - libcoap - 4.3.5b-3.fc45: normalized package name match | Fedora Rawhide package metadata: libcoap from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-primary.xml.zst | C library implementation of CoAP | https://libcoap.net/ - dnf - libcoap-devel - 4.3.5b-3.fc45: normalized package name match | Fedora Rawhide package metadata: libcoap-devel from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-primary.xml.zst | Development package for libcoap | https://libcoap.net/ - dnf - libcoap-doc - 4.3.5b-3.fc45: normalized package name match | Fedora Rawhide package metadata: libcoap-doc from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-primary.xml.zst | Documentation package for libcoap | https://libcoap.net/ - dnf - libcoap-utils - 4.3.5b-3.fc45: normalized package name match | Fedora Rawhide package metadata: libcoap-utils from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-primary.xml.zst | Client and server CoAP utilities | https://libcoap.net/ - pacman - libcoap - 4.3.5b-1: normalized package name match | Arch Linux sync databases: libcoap from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | A CoAP (RFC 7252) implementation in C | https://github.com/obgm/libcoap/ - zypper - libcoap-devel - 4.3.5b-1.4: normalized package name match | openSUSE Tumbleweed package metadata: libcoap-devel from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Development files for libcoap | https://libcoap.net/ - zypper - libcoap-utils - 4.3.5b-1.4: normalized package name match | openSUSE Tumbleweed package metadata: libcoap-utils from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Utilities for Constrained Application Protocol (CoAP) | https://libcoap.net/ - zypper - libcoap3-3 - 4.3.5b-1.4: normalized package name match | openSUSE Tumbleweed package metadata: libcoap3-3 from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | C implementation of Constrained Application Protocol (CoAP) | https://libcoap.net/ ## Combined YAML source View the package source record on GitHub.
