About:
Libsodium is a modern, easy-to-use software library for encryption, decryption, signatures, and password hashing. It is based on the NaCl (Networking and Cryptography Library) API, providing high-speed, secure cryptographic primitives. Its primary value is offering a secure, foolproof API that prevents common implementation mistakes.
Key Features:
  • High-speed, state-of-the-art cryptographic primitives
  • Simple, opinionated API designed to prevent misuse
  • Cross-platform support (Linux, Windows, macOS, BSD)
  • Bindings available for numerous programming languages
Use Cases:
  • Implementing end-to-end encryption in applications
  • Securing user passwords with memory-hard hashing (Argon2)
  • Creating and verifying digital signatures
  • Generating cryptographically secure random numbers
Alternatives:
  • OpenSSL – OpenSSL is more feature-rich but has a notoriously complex and error-prone API.
  • Libgcrypt – Libgcrypt is a general-purpose library but is often considered less modern and harder to use.
