It uses the basic MD4 function, but the password needs to be in Unicode Little Endian encode first (this canbe achieved by the iconv function).This can be done easily by using the following code:<?phpfunction NTLMHash($Input) { // Convert the password from UTF8 to UTF16 (little ...

使用HashSet需要解决一个重要问题:冲突问题。对比研究了网上一些字符串哈希函数,发现几乎所有的流行的HashMap都采用了DJB Hash Function,俗称“Times33”算法。Times33的算法很简单,就是对字符串逐字符迭代乘以33,见下面算法原型:hash(i)=33*hash(i-1)+str[i] <?php // +--- // | Perfect Is Shit // +...
