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 v2 and 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
Overview of NSS. For a list of frequently asked questions, see the FAQ.
NSS is available under the Mozilla Public License. For information on downloading NSS releases as tar files, see
