webservice(soap)接口的加密,SHA-1实现

import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

public class SoapKey {
private static String byteArrayToHex(byte[] byteArray) {
char[] hexDigits = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F' };

//计算消息摘要
