md5--加密文件
MD5 算法描述 对 MD5 算法简要的叙述可以为:MD5 以 512 位分组来处理输入的信 息,且每一分组又被划分为 16 个 32 位子分组,经过了一系列的处理后, 算法的输出由四个 32 位分组组成, 将这四个 32 位分组级联后将生成一个 128 位散列值。 在 MD5 算法中,首先需要对信息进行填充,使其字节长度对 512 求 余的结果等于 448。因此,信息的字节长度(Bits Length)将被扩展至 N*512+448,即 N*64+56 个字节(Bytes) ,N 为一个正整数。填充的方 法如下,在信息的后面填充一个 1 和无数个 0,直到满足上面的条件时才 停止用 0 对信息的填充。 请点击左侧文件开始预览 !预览只提供20%的代码片段,完整代码需下载后查看 加载中 侵权举报

2的16次幂正整数d与n,编写计算d
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.

128192和256位密钥的密码Twofish的VHDL实现。
VHDL implementation of the twofish cipher for 128,192 and 256 bit keys.
The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.-VHDL implementation of the twofish cipher for 128,192 and 256 bit keys.
