RSA算法介绍-RSA algorithm introduced

128位(或192或256bit该代码以128为例)的密钥长度和分组长度，数据分组（输入的明文），先进行逐比特异或（AddRoundKey） 运算。然后通过循环十次非线性代换（SubBytes）、行变换（ShiftRows）、列变换（MixColumns）、逐比特异或【最后一轮不进行列变换】 的过程，输出128位（或192或256bit）数据即是密文。这就是加密过程。之后进行之前的逆过程，即可得到明文，此为解密过程。

是当今比较新的算法MD5，比DES和DES5都要加密好，是dll文件，在自己写的程序中加入它，就可以直接用了，全是意接口的形式-Is the relatively new algorithm MD5, should DES5 than DES and encryption, and is a dll file, written in their own process to join it, can be directly used, the interface is intended to form ~ ~ ~ ~

LDPC的编码和译码程序，运行可靠，主要是用于4G的编码使用。matlab编程使用，核心代码简单可靠

My stuff is aimed at teaching, not efficiency. The others are probably much better implementations. The last one has both C++ and Java versions where my stuff is all C. So lots of choices!
