8051核的DES源代码 使用C语言写的基于51核的DES原码，变量定义使用汇编。占用了130字节RAM，比我所见到的包括汇编编写的都要快。 -8051 nuclear DES use source code written in C language based on the 51 nuclear DES original code, the use of variable definition compilation. Occupy the 130 byte RAM, than I have seen in the preparation of the compilation must fast.
