　　libsodium 1.0.9 发布了。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。
　　更新说明：

• 　　The Javascript target now includes a --sumo option to include all the symbols of the original C library.
  
• 　　A detached API was added to the ChaCha20-Poly1305 and AES256-GCM implementations.
  
• 　　The Argon2i password hashing function was added, and is accessible directly and through a new, high-level crypto_pwhash API. The scrypt function remains available as well.
  
• 　　A speed-record AVX2 implementation of BLAKE2b was added (thanks to Samuel Neves).
  
• 　　The library can now be compiled using C++Builder (thanks to @jcolli44)
  
• 　　Countermeasures for Ed25519 signatures malleability have been added to match the irtf-cfrg-eddsa draft (note that malleability is irrelevantto the standard definition of signature security). Signatures with a small-order R point are now also rejected.
  
• 　　Some implementations are now slightly faster when using the Clang compiler.
  
• 　　The HChaCha20 core function was implemented (crypto_core_hchacha20()).
  
• 　　No-op stubs were added for all AES256-GCM public functions even when compiled on non-Intel platforms.
  
• 　　crypt_generichash_blake2b_statebytes() was added.
  
• 　　New macros were added for the IETF variant of the ChaCha20-Poly1305 construction.
  
• 　　The library can now be compiled on Minix.
  
• 　　HEASLR is now enabled on MinGW builds.
