大二的时候写的RSA类头文件，集成了大数四则运算、幂模运算、米勒罗宾算法寻找大数等RSA加密必须的算法，详询《密码学原理与实践》-Sophomore writing the RSA class header file, integrated Tarsus four computing power modular arithmetic, Miller-Rabin algorithm must find large numbers RSA encryption algorithm, detailed

包含大整数类，RSA加解密算法类，以及RSA低加密指数攻击的实现过程。大整数类实现任意大整数（可调整）的运算，重载+、-、*、/运算符，实现模幂、模逆运算，任意次幂、开任意次方运算。RSA类实现自定义密钥的加解密算法，各种转换过程。主函数提供了当公钥e很小时恢复明文的攻击方法。-It contains BigInteger class,RSA encryption algorithm class and the implementation process of RSA low encrypti

随机搜索大素数，随机生成公钥和私钥； 要求使用素性检测算法及高效率求逆和模幂运算 用私钥对任意长度的明文签名 用公钥对签名验证；-Random search large prime Numbers, random public key and a private key Requires the use of element detection algorithm and efficient inverse power operation and mould With the

目前RSA公钥密码体制所采用的模幂运算耗时太多，处理大数据时速度很慢，所以提高运算效率便成为非常重要的研究课题，模重复平方算法通过实现指数约减达到简化计算的目的。-Currently consuming too much power operation mode RSA public-key cryptosystem used when dealing with large data speed is very slow, so improving operational efficiency
