C\C++加密庫，libsodium 1.0.3 發布

libsodium 是一個先進而且易用的加密庫。主要用于加密、解密、簽名和生成密碼哈希等等。這是一個可移植的、跨編譯器支持、可安裝的，基于 NaCI 開發，提供一個兼容 API。

libsodium 1.0.3 發布，此版本更新內容如下：

• In addition to sodium_bin2hex(), sodium_hex2bin() is now a constant-time function.

• crypto_stream_xsalsa20_ic() has been added.

• crypto_generichash_statebytes(), crypto_auth_*_statebytes() and crypto_hash_*_statebytes() have been added in order to retrieve the size of structures keeping states from foreign languages.

• The JavaScript target doesn't require /dev/urandom or an external randombytes() implementation any more. Other minor Emscripten-related improvements have been made in order to support libsodium.js

• Custom randombytes implementations do not need to provide their own implementation of randombytes_uniform() any more. randombytes_stir() and randombytes_close() can also be NULL pointers if they are not required.

• On Linux, getrandom(2) is being used instead of directly accessing /dev/urandom, if the kernel supports this system call.

• crypto_box_seal() and crypto_box_seal_open() have been added.

• A solutions for Visual Studio 2015 was added.
