Libsodium
Libsodium is a modern, easy-to-use software library for encryption, decryption, signatures, password hashing, and other cryptographic operations. It provides a high-level API that simplifies secure programming by eliminating common pitfalls and offering safe defaults. It is portable, cross-platform, and designed to be resistant to side-channel attacks.
Developers should use Libsodium when building applications that require robust security, such as secure messaging, data storage, authentication systems, or any scenario where cryptographic operations are needed. It is particularly valuable because it abstracts complex cryptographic details, reduces the risk of implementation errors, and is widely trusted in the industry for its reliability and performance.
