RbNaCl
Ruby FFI binding to libsodium, providing high-level, secure-by-default cryptographic APIs for Ruby applications.
What is RbNaCl?
RbNaCl is a Ruby FFI binding to the libsodium (Networking and Cryptography) library, providing high-level cryptographic APIs for Ruby applications. It solves the problem of complex, error-prone cryptographic configuration by offering secure-by-default interfaces for encryption, signatures, and authentication. The library uses state-of-the-art algorithms like Curve25519 and XSalsa20 to ensure both security and performance.
Ruby developers who need to implement cryptography in their applications, particularly those who want to avoid the pitfalls of low-level cryptographic primitives and prefer a secure-by-default approach.
Developers choose RbNaCl because it provides a "cryptography on Rails" experience—expertly-assembled APIs that are hard to misuse, with modern algorithms and a focus on security by design. It eliminates the need to make error-prone decisions about cryptographic primitives, unlike traditional libraries like OpenSSL.
