Jertzukka 4e112df0d2 Documentation: Remove XHTML spec and fix errors (#1547)
* Documentation: Remove XHTML spec and fix errors
None of the docs follow the XHTML specification, which means
that programs that expect this (such as Gnome Web) as it is advertised
as such, will completely fail to parse it as it is incorrect syntax. So
it is removed.

* Remove .chm files

<p>由罗斯·安德森Ross Anderson、伊莱·比哈姆Eli Biham和拉斯·克努森Lars Knudsen设计于1998年发布。它使用256位密钥、128位块并以XTS模式运行请参阅<a href="Modes%20of%20Operation.html"><em>操作模式</em></a>部分。Serpent是高级加密标准AES的最终候选算法之一。尽管它似乎比获胜的Rijndael算法具有更高的安全裕度但它并未被选为提议的AES算法[4]。更具体地说Serpent似乎具有<em></em>安全裕度而Rijndael似乎只有<em>足够</em>的安全裕度[4]。此外Rijndael的数学结构也受到了一些批评有人认为这可能会在未来导致攻击[4]。<br>
<br>
在文献[5]中Twofish团队给出了AES最终候选算法的安全系数表。安全系数的定义为完整密码的轮数除以已被破解的最大轮数。因此被破解的密码的安全系数最低为1。在AES最终候选算法中Serpent的安全系数最高为3.56适用于所有支持的密钥长度。Rijndael - 256的安全系数为1.56。<br>
<br>
尽管有这些情况但由于Rijndael在安全性、性能、效率、可实现性和灵活性方面的综合表现它被认为是AES的合适选择[4]。在最后一届AES候选算法会议上Rijndael获得了86票Serpent获得了59票Twofish获得了31票RC6获得了23票MARS获得了13票[18, 19]。*</p>
<p>* 这些是赞成票。如果从赞成票中减去反对票得到以下结果Rijndael76票Serpent52票Twofish10票RC6 - 14票MARS - 70票[19]。</p>
