libsodium is a modern, portable, easy-to-use C library for cryptographic operations, forked from NaCl with a compatible but extended API. It provides encryption, decryption, digital signatures, password hashing, key exchange, and more, with bindings for many languages and a JavaScript/WebAssembly version.

Use cases

• encrypt and decrypt data in an application
• sign and verify messages with digital signatures
• hash passwords securely
• derive keys and perform key exchange
• generate cryptographically secure random data
• build higher-level cryptographic tools on a vetted primitive set

When to choose

• you need a well-audited, high-level crypto library with a misuse-resistant API
• you need cross-platform support including mobile and WebAssembly
• you want fast implementations of modern primitives like XChaCha20 and Ed25519

When to avoid

• you need low-level control over specific primitives or custom constructions
• you require FIPS-validated cryptography
• you need a pure high-level language implementation without C dependencies
