Überblick
X.509 and CMS library
Verlauf
Libksba is GnuPG's X.509 and CMS library. It gives C applications a shared interface for parsing and handling X.509 certificates, CMS/PKCS#7 messages, certificate revocation lists, and PKCS#10 certificate requests.
GnuPG's Libksba page describes the library as a way to hide the many protocol details and dialects of X.509 certificates, CMS data, and related objects behind one C API. The README explains that KSBA is pronounced Kasbah, ships as a standard shared library, and deliberately does not rely on another cryptographic library.
The reference manual edition 1.0.6 was last updated on 2009-01-09 for KSBA 1.0.6, showing that Libksba had already stabilized as a documented component of the GnuPG library set by the late 2000s. GnuPG download metadata lists Libksba 1.8.0 on 2026-05-13.
Libksba's adoption is mostly through GnuPG and GnuPG-adjacent packaging. The README says GnuPG's dirmngr module makes extensive use of Libksba's OCSP feature, while GnuPG documentation and related manuals identify gpgsm as the X.509/CMS counterpart to gpg for S/MIME workflows.
It appears in Homebrew, Debian, Ubuntu, Fedora, Alpine, Arch, MacPorts, Nix, and openSUSE because GnuPG stacks are base security infrastructure on Unix-like systems. Users rarely install it for its own UI; they inherit it through certificate, S/MIME, and CMS support.
Developers use Libksba when they need C-level access to X.509 certificate structures, CMS messages, CRLs, PKCS#10 requests, and related parsing/serialization inside GnuPG-style applications. Packagers see ksba-config as the small build-helper executable attached to the library.
Libksba is significant because it is a quiet security plumbing package: not the cryptographic primitive library, not the mail client, and not the gpg command, but the X.509/CMS parser layer that lets GnuPG's S/MIME side exist as a separately packaged dependency.
Sicherheitslage
Für libksba wurde kein passendes lokales Secret-Handling-Manifest gefunden. Nucleus-Paketmetadaten bleiben hier veröffentlicht, damit künftige Abdeckung eine stabile Paket-URL hat.
Prüfe vor unbeaufsichtigter Agent-Nutzung, ob das Tool Klartext-Credentials liest, Remote-Zustand schreibt, Artefakte veröffentlicht oder Plugins ausführt.
