程序采用当前最先进的Rijndael算法作为核心算法，带有可变块长和可变密钥长度的迭代块密码。块长和密钥长度可以分别指定成 128、192 或 256 位。假设一台一秒内可找出DES密钥的机器(如，每秒试255个密钥)，如果用它来找出Rijndael的密钥，大约需要149万亿年。程序内部还使用了其它算法和符合密钥学的数据结构。多线程操作，保证加密时程序界面流畅,程序是用VS2005,C#做的，现将源程序发布在此。供初学者学习，希望对大家有所帮助。-procedures using the most advanced as a core Rijndael algorithm, with variable block length and variable length of the key block iterative password. Block length and key length can be designated as bit or 256. A second assumption Taiwan can identify with the DES key machines (for example, 255 per second key test), if it is used to identify the key Rijndael, approximately 149 Letters. Internal procedures are also used with other key algorithm and data structure of school. Multithreading operation to ensure that encryption program interface and smooth procedure is hashed, C# done. now source release here. For beginners learning, we hope to help.
