Amazon发布开源TLS工具s2n解决OpenSSL问题
在接下来的几个月里，amazon会部署s2n，用户则不需要做任何操作。
Amazon s2n是对libSSL（两个openssl的主库之一）的替换。
S2n的支持范围：
s2n implements SSLv3, TLS1.0, TLS1.1, and TLS1.2. For encryption, s2n supports 128-bit and 256-bit AES, in the CBC and GCM modes, 3DES, and RC4. For forward secrecy, s2n supports both DHE and ECDHE. s2n also supports the Server Name Indicator (SNI), Application-Layer Protocol Negotiation (ALPN) and the Online Certificate Status Protocol (OCSP) TLS extensions. SSLv3, RC4, and DHE are each disabled by default for security reasons.
