libsodium 是一个先进而且易用的加密库。主要用于加密、解密、签名和生成密码哈希等等。这是一个可移植的、跨编译器支持、可安装的，基于 NaCI 开发，提供一个兼容 API。
libsodium 1.0.1 发布，此版本现已提供下载，更新内容如下：
DLL_EXPORT was renamed SODIUM_DLL_EXPORT in order to avoid collisions with similar macros defined by other libraries.
sodium_bin2hex() is now constant-time.
crypto_secretbox_detached() now supports overlapping input and output regions.
NaCl's donna_c64 implementation of curve25519 was reading an extra byte past the end of the buffer containing the base point. This has been fixed.
