## Legacy Documentation
:::{container}
**Network Security Services** (**NSS**) is a set of libraries designed to support cross-platform
development of security-enabled client and server applications. Applications built with NSS can
support SSL v3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12, S/MIME, X.509 v3 certificates, and
other security standards.
For detailed information on standards supported, see {ref}`mozilla_projects_nss_overview`. For a
list of frequently asked questions, see the {ref}`mozilla_projects_nss_faq`.
NSS is available under the Mozilla Public License. For information on downloading NSS releases as
tar files, see {ref}`mozilla_projects_nss_nss_sources_building_testing`.
If you're a developer and would like to contribute to NSS, you might want to read the document
{ref}`mozilla_projects_nss_an_overview_of_nss_internals`.
