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 1.0.6 发布，此版本更新内容如下： Optimized implementations of Blake2 have been added for modern Intel platforms. crypto_generichash() is now faster than MD5 and SHA1 implementations while being far more secure. Functions for which the return value should be checked have been tagged with __attribute__ ((warn_unused_result)). This will intentionally break code compiled with -Werror that didn't bother checking critical return values. The crypto_sign_edwards25519sha512batch_*() functions have been tagged as deprecated. Undocumented symbols that were exported, but were only useful for internal purposes have been removed or made private:sodium_runtime_get_cpu_features(), the implementation-specific crypto_onetimeauth_poly1305_donna() symbols, crypto_onetimeauth_poly1305_set_implementation(), crypto_onetimeauth_poly1305_implementation_name() and crypto_onetimeauth_pick_best_implementation(). sodium_compare() now works as documented, and compares numbers in little-endian format instead of behaving like memcmp(). The previous changes should not break actual applications, but to be safe, the library version major was incremented. sodium_runtime_has_ssse3() and sodium_runtime_has_sse41() have been added. The library can now be compiled with the CompCert compiler. 下载：libsodium-1.0.6.tar.gz libsodium 1.0.6 发布，加密库下载地址
