2的16次幂正整数d与n，编写计算d-1 (mod n) 的程序； 2、对于三个不超过2的16次幂正整数a、e与n，编写计算ae (mod n) 的程序。 在上述程序基础上写出下列程序： （1） 对给定的10000以内数判定其是否为素数； （2） 进行ElGamal体制的加密与签名。 -two of 16 power-positive integer d and n, calculate the preparation of d-1 (mod n); 2. For not more than 2 3 16 Powers positive integers a, e and n, calculate the preparation ae (mod n) procedures. In the above procedure to write on the basis of the following procedures : (a) the right to 10,000 within a few judging whether a prime number; (2) ElGamal encryption and signature.

sha256。256位的sha哈希函数算法，将明文进行散列加密处理。

为了在NS2上的一些安全仿真，我试着介绍一下RSA算法。这个算法对WSN, MANET, VANET, FRID, BANET以及任何关注包安全性和数字签名的系统都非常试用。

VMP是现在最流行的加密壳 有很多朋友会觉的加了vmp很难脱 现在我就给大家展示下这个脱壳的方法(VMP is now the most popular encryption shell. Many friends will feel that adding VMP is hard to get rid of. Now I will show you the way of shelling, which is actually not as difficult as you think.)

它也可以用来解除Adobe Acrobat PDF文件密码的工具，它可以帮助解决加密PDF无法编辑和复制/打印的问题，支持所有版本的Acrobat加密(包含7.x)，也支持128位加密。 -It also can be used to lift the Adobe Acrobat PDF files password tool, it can help to solve encrypted PDF can not edit and copy/print the questions, and support all versions of Acrobat encryption (including 7.x), also supports 128-bit encryption.

看到RSA加密的C++类下载的人不少，我也下载了，并且稍微改动了一下，使它看上去更加易懂。在新年随手写了一套RSA文件加密，用win32dll封装使用了这个类，用C#写了文件加密和操作界面，可以实现密钥的保存和对任何文件的RSA加密操作。送给大家祝大家新年快乐。(see RSA encryption C downloaded to many people, I have downloaded and slightly altered a bit it looks more comprehensible. New Year threw in a written document RSA encryption, win32dll Compliant with the use of this category, C# to write document encryption and interface, can achieve key to the preservation of any documents and the RSA encryption operation. Give you wish you a happy New Year.)

DES加密算法，初始置换、密钥置换、密钥循环、密钥压缩置换、数据扩展置换、、S盒替换、P盒置换、末置换 (DES encryption algorithm, the initial replacement, key replacement, key loops, key compression replacement, data expansion permutation,, S cartridge replacement, P cartridge replacement, replacement end)

一个实现AES加密的源代码，含注释，可满足于数字签名及加密程序(Implementation of an AES encryption source code, including the Notes may be satisfied with digital signatures and encryption procedures)
