安全散列函数的VERILOG实现，通过了fpga验证，在系统正可以直接当IP盒应用-Secure Hash Function VERILOG achieve, through the FPGA verification, the system is can be directly applied when the IP box

安全散列算法的另一种verilog实现，对面积的要求更小，但损失了速度，但在一般系统中，完全可以满足大部分需要了-Secure Hash Algorithm another Verilog realization of the demands of a smaller area, but a loss of speed, but in the general system, fully satisfy the needs of the most
