About:
Network Security Services (NSS) is a set of libraries designed to support cross-platform development of security-enabled client and server applications. It provides a complete open-source implementation of cryptographic libraries supporting TLS, SSL, and other security standards. NSS is used by major software like Firefox and Thunderbird to secure network communications.
Key Features:
  • Implementation of SSL v2/v3 and TLS
  • Cryptographic module for RSA, DSA, and ECC
  • High-level PKCS #11 API for hardware tokens
  • FIPS 140-2 validated cryptographic module
  • Cross-platform support (Linux, macOS, Windows)
Use Cases:
  • Securing web browsers and email clients
  • Developing applications requiring SSL/TLS encryption
  • Implementing client-side certificate authentication
  • Building secure server applications
Alternatives:
  • OpenSSL – OpenSSL is a more ubiquitous general-purpose library, while NSS is optimized for browser integration and specific PKCS #11 standards.
