<p><strong>网络安全服务</strong> (<strong>NSS</strong>) 是一组旨在支持支持安全的客户端和服务器应用程序跨平台开发的库。使用NSS构建的应用程序可以支持 SSL v2 和 v3 、TLS 、 PKCS #5 、 PKCS #7 、 PKCS #11 、 PKCS #12 、 S/MIME 、 X.509 v3 证书以及其他安全标准。</p>

<p>有关支持的标准的详细信息，请参阅<a href="/en-US/docs/Overview_of_NSS" title="Overview_of_NSS">NSS概述</a>。有关常见问题的列表，请参阅<a href="/en-US/docs/NSS_FAQ" title="NSS_FAQ">FAQ</a>。</p>

<p>NSS可在Mozilla公共许可证下使用。有关将NSS发布版本下载为tar文件的信息，请参阅<a href="https://developer.mozilla.org/en-US/docs/NSS_Sources_Building_Testing">下载PKI源文件</a>。</p>

<p>如果您是一名开发人员，并希望为NSS做出贡献，您可能需要阅读<a href="/en-US/docs/An_overview_of_NSS_Internals" title="/en-US/docs/An_overview_of_NSS_Internals">NSS内部详细信息的文档高级概述</a>，并<a href="/en-US/docs/Getting_Started_With_NSS" title="/en-US/docs/Getting_Started_With_NSS">开始使用NSS</a>。</p>
