BlowFish加密算法-BlowFish encryption algorithm

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。

playfair的源代码，很简洁，跟网上现存的版本有所差异，但是效果是很不错的。-playfair source code is very simple, with the existing version of the web is different, but the effect is very good.

这是RC5算法的实现-This is the realization of RC5 Algorithm

Motivation - A simple DES core  - Fast and Small Version  - Open Source Compatibility I believe that the core complies to NIST-800-17. However, there has been no formal third party verification. The official NIST specification can be downloaded here: 800-17.pdf. For the Triple DES, the NIST reference is located here:
