sodium

The sodium package provides R bindings to libsodium, a modern cryptography library for encryption, decryption, digital signatures, and password hashing.

Sodium uses curve25519, a cryptographically strong Diffie-Hellman function that has gained widespread adoption. The package offers an easy-to-use interface for common cryptographic operations like public key encryption, message authentication, and key generation. It provides a secure alternative to older cryptographic systems that have known vulnerabilities.
