推荐答案

你不能。

这就是密码的全部概念：如果你不知道，你就不能找出它是什么，你不能使用受保护的资源。

你可能会发现如果你幸运的是暴力攻击，但是要准备等待很长时间才能获得结果 - 每个18个字符和62个可能的字符是您需要进行的大量尝试。

You can't.
That is the whole idea of passwords: if you don't know it, you can't find out what it is, and you can't use the resource that is protected.
You might find it if you are lucky with a brute force attack, but be prepared to wait a long time for results - 18 characters and 62 possible characters for each is a heck of a lot of attempts you will need to make.
