String testString = new String("117851010540600");
String pwd = testString.hashCode(testString);
经过查找hashCode方法的源代码.用JAVA还原出来就是:
public static int getHashCode(String s){
int hash = 0;
int off = 0;
char val[]= s.toCharArray();
int len = s.length();
for (int i = 0; i < len; i++) {
hash = 31*hash + val[off++];
}
return hash;
}
