* 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

SM4是一种分组密码标准,由中国国家密码管理局于2006年发布,并作为GB/T 32907-2016标准的一部分。它是中国用于无线通信(如Wi-Fi)及其他安全通信系统的国家加密标准。SM4在128位数据块上运行,使用128位加密密钥。

|
||
SM4算法采用32轮加密操作,结合了非线性代换、线性变换和密钥加运算。其结构在某些方面与其他现代分组密码类似,采用S盒进行代换,并通过线性变换实现扩散。

SM4已被国际标准化组织/国际电工委员会(ISO/IEC)正式标准化,标准编号为ISO/IEC 18033-3:2010,并已广泛应用于中国的政府、银行和商业领域。该算法针对软硬件实现均进行了优化,在保证强大安全性的同时,具备较高的性能。
