密码学文献有一个奇妙的发展历程，当然，密而不宣总是扮演主要角色。第一次世界大战前，重要的密码学进展很少出现在公开文献中，但该领域却和其它专业学科一样向前发展。-cryptography literature has a wonderful history, of course, close does not declare always played the leading role. Before the First World War, it was important to cryptography little progress emerged in the open literature. However, the area has other professional disciplines and the development of the same.

编程中获得会话密钥匙非常重要的 MSDN 展示了一种使用私钥的方法。 但是微软的这个在MSDN中例子相当的长。 本文下面介绍的这个方法不仅更快而且更有效 -Programming cryptographic key conversation was very important MSDN demonstrated a method of using the private key. But in Microsoft"s MSDN examples longer. Presented below is the method not only faster and more effectively
