This NSS documentation was just imported from our legacy MDN repository. It
currently is very deprecated and likely incorrect or broken in many places.
.. 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.
NSS is available under the Mozilla Public License v2 (MPLv2).
If you're a developer and would like to contribute to NSS, you might want to
