花了两天时间终于把rsa加密算法弄出来了,虽然效率有点低,但是自己感觉还是蛮不错的,窃喜中.........

开发工具是netbeans 哈哈

这个是公共文件 Config.java

/* * To change this template, choose Tools | Templates * and open the template in the editor. */ package rsa; /** * * @author Administrator */ public class Config { private int randomBaseNum; //随机生成素数的长度 private long primeP, //随机质数A primeQ, //随机质数B NumN, //A和B的乘积N eulerFun, //欧拉函数 primeE, //欧拉内的互质数 numD; //求模后的数 private long[] PK, //公钥 SK; //私钥 /** * 得到生成素数的基 * @return the randomBaseNum */ public int getRandomBaseNum() { return randomBaseNum; } /** * 设置随机生成的素数的基 * @param randomBaseNum the randomBaseNum to set */ public void setRandomBaseNum(int randomBaseNum) { this.randomBaseNum = randomBaseNum; } /** * @return the primeP */ public long getPrimeP() { return primeP; } /** * @param primeP the primeP to set */ public void setPrimeP(long primeP) { this.primeP = primeP; } /** * @return the primeQ */ public long getPrimeQ() { return primeQ; } /** * @param primeQ the primeQ to set */ public void setPrimeQ(long primeQ) { this.primeQ = primeQ; } /** * @return the NumN */ public long getNumN() { return NumN; } /** * @param NumN the NumN to set */ public void setNumN(long NumN) { this.NumN = NumN; } /** * @return the eulerFun */ public long getEulerFun() { return eulerFun; } /** * @param eulerFun the eulerFun to set */ public void setEulerFun(long eulerFun) { this.eulerFun = eulerFun; } /** * @return the primeE */ public long getPrimeE() { return primeE; } /** * @param primeE the primeE to set */ public void setPrimeE(long primeE) { this.primeE = primeE; } /** * @return the numD */ public long getNumD() { return numD; } /** * @param numD the numD to set */ public void setNumD(long numD) { this.numD = numD; } /** * @return the PK */ public long[] getPK() { return PK; } /** * @param PK the PK to set */ public void setPK(long[] PK) { this.PK = PK; } /** * @return the SK */ public long[] getSK() { return SK; } /** * @param SK the SK to set */ public void setSK(long[] SK) { this.SK = SK; } }

这个是随机生成素数的类:RSARandomPrime.java

/* * 应用举例 * ① 选择两个素数p = 7，q = 17。 * ② 计算n = p·q = 7×17 = 119。 * 计算n的欧拉函数φ(n) = ( p - 1)(q - 1) = 6×16 = 96。 * ③ 从[0，95]间选一个与96互质的数e = 5，根据式 * 5·d = 1 mod 96 * 解出d = 77，因为e·d = 5×77 = 385 = 4×96 + 1 = 1 mod 96。 * ④ 得到公钥PK = (e,n) = {5,119}，密钥SK = {77,119}。 * */ package rsa; import java.util.Vector; /** * * @author Administrator */ public class RSARandomPrime extends Config { public RSARandomPrime(int base) throws NotBaseNumException { this.setRandomBaseNum(base); //设置生成素数的基 this.setPrimeP(this.getPrimeNum()); //设置素数p的值 this.setPrimeQ(this.getPrimeNum()); //设置素数q的值 this.setNumN(this.getPrimeP() * this.getPrimeQ()); //设置p和q 的乘积 n this.setEulerFun((this.getPrimeP() - 1) * (this.getPrimeQ() - 1)); //设置欧拉函数的值 this.setPrimeE(this.primeE()); this.setNumD(this.numD()); this.setPK(this.PK()); this.setSK(this.SK()); } /** * 随机产生指定长度的素数 * @return long型素数 * @throws NotBaseNumException 所要生成的素数长度为0 */ public long getPrimeNum() throws NotBaseNumException { if (getRandomBaseNum() <= 0) { throw new NotBaseNumException(); } else { long primeNum = 0; //用来存储最终素数 Vector<Long> primeVc = new Vector<Long>(); //指定存素数的vector long low = (long) Math.pow(10, getRandomBaseNum() - 1); //指定生成素数范围的最小值 long high = (long) Math.pow(10, getRandomBaseNum()) - 1; //指定生成素数范围的最大值 //生成指定范围的素数 for (long temp = low; temp < high; temp++) { if (this.validatePrime(temp)) { primeVc.add(temp); } } //生成一个随机数,这个随机数在vector的长度内 int randomNum = (int) (Math.random() * (Math.pow(10, getRandomBaseNum())) % primeVc.size()); //取出指定位置的素数 primeNum = primeVc.get(randomNum); return primeNum; } } /** * 获取欧拉数内的互质数 * @return 质数 */ public long primeE() { long primeNum = 0; while (!this.validatePrime(primeNum)) { //随机生成一个数,这个数的大小在指定长度的位数范围内 primeNum = (long) (((Math.random()) * (Math.pow(10, getRandomBaseNum() * 2))) % (this.getEulerFun() - 1)); } //System.out.println("euler: "+eulerFun+"; primeNum: "+primeNum); return primeNum; } /** * 生成D * @return 质数 */ public long numD() { long d = 0; /* for (int i = 0; i < 99; i++) { if (((i * primeE) % eulerFun) == 1) { d = i; } } */ //long i = 0; long i = (long) (Math.random() * Math.pow(10, this.getRandomBaseNum())); while (true) { i++; if (((i * this.getPrimeE()) % this.getEulerFun()) == 1) { d = i; break; } } return d; } /** * 验证输入的数字是否为素数 * @param tempPrimeNum 输入的数字 * @return 如果是的话就返回true反之亦然 */ public boolean validatePrime(long tempPrimeNum) { boolean flag = false; if (tempPrimeNum < 2) { flag = false; } else { for (long temp = 2; temp <= Math.sqrt(tempPrimeNum); temp++) { if (tempPrimeNum % temp == 0) { flag = false; break; } flag = true; } } return flag; } /** * 得到公钥 * @return */ public long[] PK() { long[] pk = new long[]{this.getPrimeE(), this.getNumN()}; return pk; } /** * 得到密钥 * @return */ public long[] SK() { long[] sk = new long[]{this.getNumD(), this.getNumN()}; return sk; } public static void main(String args[]) throws NotBaseNumException { RSARandomPrime rsar = new RSARandomPrime(3); System.out.println("p: " + rsar.getPrimeP() + "; q" + ": " + rsar.getPrimeQ() + "; chengji: " + rsar.getNumN() + "; eulurNum: " + rsar.getEulerFun() + "; E: " + rsar.getPrimeE() + "; D: " + rsar.getNumD() + "; 公钥; [" + rsar.getPK()[0] + ":" + rsar.getPK()[1] + "]; 密钥: [" + rsar.getSK()[0] + ":" + rsar.getSK()[1] + "]"); } }

呵呵帖完了

整个工程在纯Java模式下无法运行的,要在netbeans下才能正常运行,我将源文件和工程打了个包!~~
