NSS Tools

NSS Security Tools

Newsgroup: mozilla.dev.tech.crypto

Overview

The NSS Security Tools allow developers to test, debug, and manage applications that use NSS. The Tools Information table below describes both the tools that are currently working and those that are still under development. The links for each tool take you to the source code, documentation, plans, and related links for each tool. The links will become active when information is available.

Currently, you must download the NSS 3.1 source and build it to create binary files for the NSS tools. For information about downloading the NSS source, see Building NSS.

If you have feedback or questions, please feel free to post to mozilla.dev.tech.crypto. This newsgroup is the preferred forum for all questions about NSS and NSS tools.

Overall Objectives

  1. Provide a tool for analyzing and repairing certificate databases (dbck).

  2. Migrate tools from secutil.h interface to PKCS #11 interface.

  3. Eliminate redundant functionality in tools. Many tools implement private versions of PKCS11Init(), OpenCertDB(), etc.

  4. Eliminate use of getopt() and replace with NSPR calls to get command options (to eliminate platform dependencies with getopt()).

modutil 1.1

Manage the database of PKCS11 modules (secmod.db). Add modules and modify the properties of existing modules (such as whether a module is the default provider of some crypto service).

signver 1.1

sslstrength

SSL Strength

:ref:` mozilla_projects_nss_tools_sslstrength`

ssltap 3.2

Proxy requests for an SSL server and display the contents of the messages exchanged between the client and server. The ssltap tool does not decrypt data, but it shows things like the type of SSL message (clientHello, serverHello, etc) and connection data (protocol version, cipher suite, etc). This tool is very useful for debugging.
