プロジェクトの歴史

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.

採用の歴史

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.

使われ方

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.

パッケージ好きにとっての重要性

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.
