Its command-line tool, xmlsec1, made XML digital-signature verification and signing scriptable on Unix-like systems. ### Project history Aleksey Sanin released XML Security Library 0.0.1 on 2002-03-17. Within weeks the project added online XML signature verification, test-suite work, a mailing list, RPM packages, and XML Encryption support. The 1.0.0 release on 2003-04-17 was a major upgrade from the 0.0.x series, adding multiple crypto engines with support for OpenSSL, GnuTLS, and NSS, plus cleaned-up internals, documentation, tutorials, and examples. The project later maintained crypto-backend support for platform engines such as Microsoft CryptoAPI and MSCNG. ### Adoption history xmlsec entered packaging systems because XML signatures are part of standards-heavy environments: SAML, document signing, SOAP-era security stacks, identity federation, and government or enterprise XML workflows. The project also published interoperability reports for XML Digital Signature and XML Encryption, which helped it function as a reference-quality implementation rather than a private library. ### How it is used The package provides both a C library and the xmlsec1 CLI. Users sign, verify, encrypt, and decrypt XML documents, usually while selecting a crypto backend and supplying keys, certificates, or trust material through command-line options or application code. ### Why package nerds care libxmlsec1 is significant because it connects the XML parser stack to the cryptographic stack. Its ABI, crypto backend defaults, and security hardening choices can affect language bindings and applications that validate signed XML, so distributions treat it as security-sensitive plumbing rather than a casual XML helper. ### Timeline - 2002: XML Security Library 0.0.1 was released on 2002-03-17. - 2002: XML Encryption support appeared in the 0.0.3 release on 2002-04-16. - 2003: XML Security Library 1.0.0 was released on 2003-04-17 with multiple crypto-engine support. - 2023: XML Security Library 1.3.0 introduced ABI and API breaking changes for newer XML Signature and Encryption behavior. - 2026: XML Security Library 1.3.12 was announced on 2026-06-23 with additional crypto-algorithm support and transform-depth controls. ### Related projects - xmlsec is built around libxml2 and related XML standards such as XML Signature, XML Encryption, Canonical XML, and Exclusive Canonical XML. Its crypto backends include OpenSSL, GnuTLS, NSS, and Windows crypto providers. ### Sources - - - - ## Security Notes library-like package without higher-risk signals. - **Geiger risk:** green / low -
