Whirlpool算法被列入了ISO标准。主要原因是因为其强大的安全度。第一点，Whirlpool使用了和AES加密标准相同的转化技术，只不过，AES使用的模函数为：f(x) = x^8 + x^4 + x^3 + x + 1, 即0x11B；而Whirlpool使用的是：f(x) = x^8 + x^4 + x^3 + x^2 + 1, 即0x11D。第二点，Whirlpool的输出是512位的。为了加快计算速度，Whirlpool使用的所有表格都已经时间计算好了。Whirlpool在历史上共有3个版本，根据最新的2003年版本，我们把目前的Whirlpool算法叫做Whirlpool 3.0。



以下是其具体代码实现。-Whirlpool algorithm was included in the ISO standard. This is mainly because of their strong safety. First, the use of the Whirlpool and AES encryption standard into the same technology, only the use of AES module functions : f (x) = x ^ x ^ 8 x 4 x 1 ^ 3, 0x11B; Whirlpool and the use of : f (x) = 8 x ^ x ^ 4 x ^ x ^ 2 3 1 that 0x11D. The second point, Whirlpool is the output of 512. To speed up the computing speed, Whirlpool use all forms have a good time basis. Whirlpool in history, a total of three versions, according to the latest 2003 edition, we present the algorithm called Whirlpool Whirlpool 3.0. Following is the specific implementation of the code.
