Its motivation came from GnuPG mailing-list discussions in 2004 and 2006 about PKCS#11 support and an unmaintained patch. The README credits Zeljko Vrba and Alon Bar-Lev, with copyright years beginning in 2006. The SourceForge project page shows release activity for the 0.7, 0.8 and 0.9 series during 2017. ### Adoption history Adoption is specialized: the tool serves users who already manage keys in PKCS#11-compatible hardware tokens or smart cards and want those keys available to GnuPG through the scdaemon interface. ### How it is used Practitioners use it as a drop-in or near-drop-in scdaemon replacement for GnuPG, typically in setups involving OpenSC, vendor PKCS#11 modules, smart cards, hardware tokens or enterprise certificate devices. ### Why package nerds care The package matters in packaging ecosystems because it fills a narrow interoperability gap: GnuPG's OpenPGP tooling on one side, PKCS#11 token middleware on the other. That makes it useful for people who need hardware-backed signing or decryption without migrating keys into GnuPG's native smart-card path. ### Timeline - 2004: GnuPG mailing-list discussions raised PKCS#11 smart-card integration questions. - 2006: Project copyright history began for the daemon implementation. - 2017: The project page announced 0.7.6, 0.8.0 and 0.9.0 releases. ### Related projects - gnupg-pkcs11-scd sits between GnuPG, scdaemon, PKCS#11 providers and token stacks such as OpenSC or vendor-supplied modules. ### Sources - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Other Package-Manager Records - Debian apt - gnupg-pkcs11-scd - 0.10.0-5+b1: normalized package name match | Debian stable package indexes: gnupg-pkcs11-scd from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | GnuPG smart-card daemon with PKCS#11 support | http://gnupg-pkcs11.sourceforge.net/ - Debian apt - gnupg-pkcs11-scd-proxy - 0.10.0-5+b1: normalized package name match | Debian stable package indexes: gnupg-pkcs11-scd-proxy from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | GnuPG smart-card daemon with PKCS#11 support, proxy | http://gnupg-pkcs11.sourceforge.net/ - Nix - gnupg-pkcs11-scd: normalized package name match | nixpkgs package indexes: pkgs/by-name/gn/gnupg-pkcs11-scd/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - gnupg-pkcs11-scd - 0.10.0-3build2: normalized package name match | Ubuntu 24.04 LTS package indexes: gnupg-pkcs11-scd from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | GnuPG smart-card daemon with PKCS#11 support | http://gnupg-pkcs11.sourceforge.net/ - Ubuntu apt - gnupg-pkcs11-scd-proxy - 0.10.0-3build2: normalized package name match | Ubuntu 24.04 LTS package indexes: gnupg-pkcs11-scd-proxy from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | GnuPG smart-card daemon with PKCS#11 support, proxy | http://gnupg-pkcs11.sourceforge.net/ - dnf - gnupg-pkcs11-scd - 0.11.0-7.fc45: normalized package name match | Fedora Rawhide package metadata: gnupg-pkcs11-scd from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-primary.xml.zst | GnuPG-compatible smart-card daemon with PKCS#11 support | http://gnupg-pkcs11.sourceforge.net - MacPorts - gnupg-pkcs11-scd: normalized package name match | MacPorts ports tree: security/gnupg-pkcs11-scd/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
