//! Rust bindings to the [sodium library](https://github.com/jedisct1/libsodium). //! //! Sodium is a portable implementation of Dan Bernsteins [`NaCl`: Networking and //! Cryptography library](http://nacl.cr.yp.to) //! //! For most users, if you want public-key (asymmetric) cryptography you should use //! the functions in [`crypto::box_`](crypto/box_/index.html) for encryption/decryption. //! //! If you want secret-key (symmetric) cryptography you should be using the //! functions in [`crypto::secretbox`](crypto/secretbox/index.html) for encryption/decryption. //! //! For public-key signatures you should use the functions in //! [`crypto::sign`](crypto/sign/index.html) for signature creation and verification. //! //! Unless you know what you're doing you most certainly don't want to use the //! functions in [`crypto::scalarmult`](crypto/scalarmult/index.html), //! [`crypto::stream`](crypto/stream/index.html), [`crypto::auth`](crypto/auth/index.html) and //! [`crypto::onetimeauth`](crypto/onetimeauth/index.html). //! //! ## Thread Safety //! All functions in this library are thread-safe provided that the [`init()`](fn.init.html) //! function has been called during program execution. //! //! If [`init()`](fn.init.html) hasn't been called then all functions except the random-number //! generation functions and the key-generation functions are thread-safe. //! //! # Public-key cryptography //!
