64位汇编语言之RSA加密算法（64位汇编语言之RSA加密算法）

RSA算法广泛地应用在计算机行业：应用软件使用数字签名防止软件被篡改那怕只修改一个bit也会被检测到

软件有没有被病毒感染查看数字证书倒是一个好方法

windows驱动程序必须要数字签名才能正常运行，商业软件VMP(VMProtect)使用RSA算法来保护软件的有效使用权限

VMP 保护软件不被逆向跟踪，使付费软件开发者把更多精力放在产品功能上。

VMP保护的代码分析起来让人抓狂，整个代码会被压缩存放，运行时现场解压，正常的API调用会被隐藏，正常的IF ELSE 分支给你用虚拟代码膨胀到几十万行代码.......本人也是研究它RSA加密运算的简便方法时在虚拟代码中迷失了。。。。。.扯得有点远。以下代码参考了它的方法。
