md5加密方法
import java.security.*;String md5(String s){
char hexDigits[] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
'a', 'b', 'c', 'd', 'e', 'f' };
try {
byte[] strTemp = s.getBytes();
MessageDigest mdTemp = MessageDigest.getInstance("MD5");
mdTemp.update(strTemp);
byte[] md = mdTemp.digest();
int j = md.length;
char str[] = new char;
int k = 0;
for (int i = 0; i < j; i++) {
byte byte0 = md;
str = hexDigits;
str = hexDigits;
}
return new String(str);
} catch (Exception e) {
return null;
}
