PB使用MD5加密,可以有效解决PB开发中登录密码使用明文的问题-PB using MD5 encryption, can effectively resolve the PB Password development issue of the use of explicit

DES加密算法的实现和演示，具体算法见网上，程序中有注释-DES encryption algorithm and demonstrate the achievement of the specific algorithm see online, proceedings have Notes

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.
