加密庫，libsodium 1.0.4 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。

• Support for AES256-GCM has been added. This requires a CPU with the aesni and pclmul extensions, and is accessible via the crypto_aead_aes256gcm_*() functions.

• The Javascript target doesn't use eval() any more, so that the library can be used in Chrome packaged applications.

• QNX and CloudABI are now supported.

• Support for NaCl has finally been added.

• ChaCha20 with an extended (96 bit) nonce and a 32-bit counter has been implemented as crypto_stream_chacha20_ietf(), crypto_stream_chacha20_ietf_xor() and crypto_stream_chacha20_ietf_xor_ic(). An IETF-compatible version of ChaCha20Poly1305 is available as crypto_aead_chacha20poly1305_ietf_npubbytes(), crypto_aead_chacha20poly1305_ietf_encrypt() and crypto_aead_chacha20poly1305_ietf_decrypt().

• The sodium_increment() helper function has been added, to increment an arbitrary large number (such as a nonce).

• The sodium_compare() helper function has been added, to compare arbitrary large numbers (such as nonces, in order to prevent replay attacks).
