1337（leet）语言一共分两个加密阶段，一个是初级加密阶段，它仅仅会把某些英文字母进行替换，替换规则如下：　0 1 3 4 5 6 7|　o l e a s g t i　于是譬如jiuxiao就会被写成j|ux|40.其实你会发现它就是一种简单的象形字母，但是这么写会有什么好处呢？大家知道在暴力破解中，一般的黑客字典是一定会*有“root““admin““god“之类的密码的，因为特别是在国外，有很多人都在用这种密码。如果暴力破解来，成功率应该会达到很大。但是如果你用骇客语进行形容的话就会变成“r007““4dm|n““60d“，这样如果是依靠字典的暴力破解基本上不会猜到，但是如果是穷举式的暴力破解依然会猜解到，于是高级的加密阶段可以来解决这个问题：譬如jiuxiao被加密成_|||_|><|40，原来的7个字符被加密成了11个字符，而且由大量的特殊字符组成，这样的11位密码的短期的暴力破解可能性几乎为0。　所以黑客语的第一个用途是加密密码（并且这个密码你是完全可以用大脑记住的）下面是一种通用的二级加密方式，大家可以参考一下：

你上搜索引擎查h4ck3r可能不会特别多，但是如果你查h4x0r就会发现有很多，而且有很多人来用它做用户名之类。
