SHA1汇编码的深度优化改写:
写个程序,用的了SHA1汇编码,百度了一堆,但是没有一个满意的。
并且都对500M以上的大文件支持不好,可怜单位配的256M内存的古董机!!!!!
于是自己决定重新写个,该源码对大文件的计算速度较快.
程序改写要点,除了对算子的优化外,还优化掉了数据表。由于优化掉了部分特种码,可以一定程度上避免PEiD类的软件侦测到所采用的算法类型
写完后,发现:中间那一堆代码怎么看怎么那么不顺眼呢!!,继续改写,进行了优化,把中间的算子优化掉。
附带全部RadASM汇编源码及生成的程序。源码请看附件。-Depth SHA1 assembly code optimization rewritten: Write a program using SHA1 assembly code, Baidu a bunch, but no one satisfied. And are bad, poor unit with large file support more than 500M 256M memory antique machine! ! ! ! ! Decide to re-write the calculation of the source of large files faster. Program overwrites points, in addition to the optimization of the operator, and also optimize away the data table. Optimize away some special code, can to some extent avoid PEiD software detects the type of algorithm used written: the middle of a pile of code to see how how then is not pleasing to the eye it! ! Continue to be rewritten and optimized to optimize away the middle of the operator. Fringe all RadASM assembler source program and generate. Source See Annex.
