盐、MD5和UUID对密码进行加密

 不要管方法名，我就是随便谷歌翻译的。

public class Encryption {
    /**
     * 基于salt、md5和uuid加密密码
     * @param password 密码
     * @param salt 盐
     * @return
     */
    public String EncryptPasswordBasedOnSaltAndMd5AndUuid(String password , String salt){
        //加密规则
        //在密码左右两边拼接一次盐值
        String passwordSalt = salt + password + salt;
        //生成UUID
        String randomUUID = UUID.randomUUID().toString();
        //拼接后的密码在前后拼接上salt、password、UUID
        String passwordSaltUUID = randomUUID + salt + passwordSalt + randomUUID + salt;
        //将最终拼接完成的密码通过for循环进行md5加密5次
        for(int i = 0; i < 5; i++){
            passwordSaltUUID = DigestUtils.md5DigestAsHex(passwordSaltUUID.getBytes());
        }
        return passwordSaltUUID;
    }
}
