这是一个压缩/解压例程使用哈夫曼编码/解码，并且最适合在普通文本的文件。代码是 * 高度 * 进行了优化，并表明这是如何快速我可以提到另一个发现这里在 planetsourcecode （从 2000 年 8 月 1 日) 也采用哈夫曼编码的代码样本。该代码用了 127 秒压缩 1.8 mb 文本文件，但与我的代码，这需要小于 1 秒 ！！(唐山的零时 12700%!!)。其他代码是值得 7 的优异点，这个价值是多少吗？

基于md5和sha1的HMAC程序。程序的功能是给定密钥计算任意长度的文件的HMAC值，验证一个文件的HMAC值是否是一个给定值。程序的使用接口不限，HMAC的计算和验证功能在一个单独的程序中实现(Based on the md5 and sha1 HMAC program. Program function is given key computing random length of the file HMAC value to verify a file s HMAC value is a given value. The use of any program interface, HMAC calculation and verification function in a separate program to realize )

The use of FPGAs for cryptographic applications is highly attractive for a variety of reasons but at the same time there are many open issues related to the general security of FPGAs. This contribution attempts to provide a state-of-the-art description of this topic. First, the advantages of reconfigurable hardware for cryptographic applications are discussed from a systems perspective. Second, potential security problems of FPGAs are described in detail, followed by a proposal of a some countermeasure. Third, a list of open research problems is provided. Even though there have been many contributions dealing with the algorithmic aspects of cryptographic schemes implemented on FPGAs, this contribution appears to be the first comprehensive treatment of system and security aspects.

SPN密码实现和分析（也就是破解），通过文件读入！(SPN password implementation and analysis (ie cracked), read through the file!)

这个例子描述了MD4碰撞，很有研究价值，大家可以仔细研究下-MD4碰撞

This is the program to encrypt and decrypt a text using AES algorihm
