Java简单的加密解密算法，使用异或运算
实例1：
package cn.std.util;
import java.nio.charset.Charset;
public class DeEnCode {
private static final String key0 = "FECOI()*&
private static final Charset charset = Charset.forName("UTF-8");
private static byte[] keyBytes = key0.getBytes(charset);
public static String encode(String enc){
byte[] b = enc.getBytes(charset);
for (int i=0,size=b.length;i
for (byte keyBytes0:keyBytes){
b[i] = (byte) (b[i]^keyBytes0);
}
}
return new String(b);
}
public static String decode(String dec){
byte[] e = dec.getBytes(charset);
byte[] dee = e;
for (int i=0,size=e.length;i
for (byte keyBytes0:keyBytes){
e[i] = (byte) (dee[i]^keyBytes0);
}
}
return new String(e);
}
public static void main(String[] args) {
String s="you are right";
String enc = encode(s);
String dec = decode(enc);
System.out.println(enc);
System.out.println(dec);
}
}
实例2
public static String setEncrypt(String str){
String sn="ziyu";
//密钥
int[] snNum=new int[str.length()];
String result="";
String temp="";
for (int i=0,j=0;i
if(j==sn.length())
j=0;
snNum[i]=str.charAt(i)^sn.charAt(j);
}
for (int k=0;k
if(snNum[k]<10){
temp="00"+snNum[k];
} else{
if(snNum[k]<100){
temp="0"+snNum[k];
}
}
result+=temp;
}
return result;
}
public static String getEncrypt(String str){
String sn="ziyu";
//密钥
char[] snNum=new char[str.length()/3];
String result="";
for (int i=0,j=0;i
if(j==sn.length())
j=0;
int n=Integer.parseint(str.substring(i*3,i*3+3));
snNum[i]=(char)((char)n^sn.charAt(j));
}
for (int k=0;k
result+=snNum[k];
}
return result;
}
}
