libsodium 1.0.4 发布加密库

libsodium 1.0.4 发布，此版本更新内容如下：

• 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 ascrypto_stream_chacha20_ietf(), crypto_stream_chacha20_ietf_xor() andcrypto_stream_chacha20_ietf_xor_ic(). An IETF-compatible version of ChaCha20Poly1305 is available as crypto_aead_chacha20poly1305_ietf_npubbytes(),crypto_aead_chacha20poly1305_ietf_encrypt() andcrypto_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).
