MD5 加密

news 2025/8/6 13:00:31

任务：

接到一个任务，调用对方的接口，内容和密码，需要使用md5进行加密，再发送请求。

参数说明：

参数名称	说明	备注
timespan	时间戳	格式为yyyyMMddHHmmss
pwd	密码	此处用原始密码+时间戳做MD5加密，32位大写格式
msgfmt	编码类型	选填，如果不填默认为GBK，可以选填GBK或者UTF8/UTF-8
content	内容	做base64编码操作,编码方式使用msgfmt中的方式，如果msgfmt有值的话

处理：

bast64编码处理：

md5

import org.apache.commons.codec.digest.DigestUtils;public class Md5Utils {/*** @param text 明文* @param key 密钥* @return 密文*/public static String md5(String text, String key) throws Exception {// 加密后的字符串String md5str = DigestUtils.md5Hex(text + key);System.out.println("MD5加密后的字符串为:" + md5str);return md5str;}/***  直接加密* @param text 明文* @return* @throws Exception*/public static String md5(String text) throws Exception {// 加密后的字符串String md5str = DigestUtils.md5Hex(text);System.out.println("MD5加密后的字符串为:" + md5str);return md5str;}/***  直接加密后变成大写* @param text 明文* @return* @throws Exception*/public static String md5Upper(String text) throws Exception {// 加密后的字符串String md5StrUp = DigestUtils.md5Hex(text).toUpperCase();System.out.println("MD5加密后大写的字符串为:" + md5StrUp);return md5StrUp;}public static void main(String args[]) throws Exception {String currentTimeSuffix = DatesUtils.getCurrentTimeSuffix();String pwd = "042556";md5(pwd, currentTimeSuffix);String pwdStr = "04255620230525112132";String pwdMdStr = md5Upper(pwdStr);System.out.println(pwdMdStr);}
