About:
OpenSSL 3.0 is a robust, full-featured open-source toolkit implementing the Transport Layer Security (TLS) protocol. It provides a comprehensive library of cryptographic algorithms, including symmetric ciphers, hash functions, and digital signatures. Its main value is enabling developers to secure network communications and manage digital certificates within their applications.
Key Features:
  • Implements TLS/SSL protocols for secure communication
  • Extensive library of cryptographic algorithms (ciphers, digests)
  • Supports FIPS 140-2 validated cryptographic module
  • Provider architecture for pluggable cryptographic modules
Use Cases:
  • Securing web servers and APIs with HTTPS
  • Implementing client-side encryption for data protection
  • Generating and managing digital certificates and keys
Alternatives:
  • LibreSSL – A fork of OpenSSL focused on code clarity and security, often preferred in BSD systems.
  • BoringSSL – Google's fork of OpenSSL, optimized for their specific needs and stripped of legacy features.
