Botan 1.10.6 发布，C++ 加密算法库

Botan 是一个 C++ 的加密算法库，支持 AES, DES, SHA-1, RSA, DSA, Diffie-Hellman 等多种算法，支持 X.509 认证以及CRLs 和 PKCS #10 ，这里是一段示例代码。

Botan 1.10.6 改进记录：

• A previously conditional operation in Montgomery multiplication and squaring is now always performed, removing a possible timing channel.
• A potential crash in the AES-NI implementation of the AES-192 key schedule (caused by misaligned loads) has been fixed.
  
• The correct flags for creating a shared library on OS X under Clang are now used, and a compile time incompatibility with Visual C++ 2012 has been fixed.
