Chapter 171 Key Exchange

Musk really wanted to know who sent the email.

This has fueled the topic of "Looking for Musk's long-lost brother."

It is rare that this topic has become a hot search on the global Internet.

[The Minister of Efficiency, Prince Ma, is looking for his long-lost brother. ]

After several VPN transfers, Lin Yuan set up his temporary mail server again on an overseas server.

He would not apply for a social platform account to send messages to Musk. Because applying for an account inevitably requires leaving a mobile phone number or contact email address, and then receiving a verification code or registration link, etc. This would leave too many online traces.

This won't happen if you use your own makeshift mail server.

After use, the entire server will be formatted, leaving no historical data.

Out of curiosity, Lin Yuan restored his previous email address - the same address he used to send the first email to the old boy at Mar-a-Lago.

Lin Yuan had a hunch that if a technology fanatic like Musk really wanted to find him as he had publicly stated, he would definitely send a reply to this email address that he had already cancelled.

Because of this sender's email address, Musk did not make it public on social platforms.

This is the only connection between Musk and Lin Yuan at present.

【[email protected]】

This is the email address used by Lin Yuan, which contains a very common domain name - domain202401.com.

This kind of domain name can be found everywhere in the trading market and can be purchased with money. Domestic transactions of domain names require real-name registration. However, internationally, this is not the case.

In short, getting a domain name is easy.

Logically speaking, Lin Yuan should not use this domain name for the second time, just like he should not use a mobile phone card for the second time.

However, he couldn't suppress his curiosity. And he also needed to contact Musk directly at this moment, otherwise he could only send an email to the old boy's donation email address. God didn't know if the other party would help forward it this time. Lin Yuan couldn't donate 10,000 US dollars in digital currency to the other party every time he sent an email.

Lin Yuan quickly set up a mail server and set up resolution for the domain name.

Two or three minutes later, there was one more email in the server's email database.

Lin Yuan immediately took the server offline.

He opened the email.

Sure enough, it was a reply letter from Musk.

【Bro, this is an invitation letter. 】

The email title is empty. The content is just a long string of characters and an email address, except for this sentence.

Lin Yuan, who works in the IT industry, reacted instantly.

Could this string be the RSA public key?

RSA.

This is the most widely used asymmetric encryption method in the world today.

Payment platforms, financial institutions, etc., are used in almost any scenario that requires data privacy.

The power of RSA lies in its asymmetry - through a pair of keys, public key A and private key B. Zhang San can encrypt with public key A, and then send the encrypted result to Li Si, who then decrypts the encrypted result with private key B. Then he can get what Zhang San wants to say.

The result of encryption is public and can be seen by anyone. Public key A can also be public.

Anyway, it is impossible to decrypt if you get the encryption result and public key A at the same time. You must get private key B.

And now, Lin Yuan seems to have received the public key A.

So what does Musk mean by sending this?

He gave public key A to Lin Yuan, and the private key B must be kept in the other party's hands.

This obviously means becoming an internet pen pal with Lin Yuan.

Lin Yuan found an RSA signing tool in a few minutes, generated a pair of RSA keys, and planned to send his public key A. In this way, Musk and Lin Yuan could send encrypted data to each other in the future.

This is tacit understanding.

Because everything running on the Internet is public, it can be intercepted in theory. Otherwise, the ancient profession of cryptographer would not exist.

Therefore, communications must be encrypted.

Lin Yuan quickly sent a reply email. He sent the subsequent communication method between the two parties in the form of encrypted data, and also sent his public key A.

Afterwards, Lin Yuan immediately blew up the temporary server and completely formatted it.

Lin Yuan did not plan to communicate with Musk via email anymore, so he used an extremely tricky method.
-
Musk intuitively felt that the bro he was looking for would definitely come to him.

So he kept sending emails to the source address.

It's like, you keep writing letters to a place called "Five and a Quarter Station". The Internet will keep finding this place for you.

Lin Yuan had just put the domain name of this place online. With the capture of the DNS, the email was naturally delivered.

Musk was excited when he received the notification that the email was successfully delivered.

There were few things that could still interest him, and launching a rocket was a distant and long task. The mysterious bro in front of him was obviously very interesting.

Not long after, he received a reply.

As expected, the other party understood what he meant.

Musk is a programmer by training, and his first entrepreneurial project was coded by himself.

"Bro, you are indeed my colleague."

Musk sent a public key A without any additional explanation, and Lin Yuan tacitly returned the public key A belonging to Lin Yuan.

Okay, now the two people have completed the key exchange.

"Bro, let's start a nice chat."

Of course, these are just Musl's own words.

When he wanted to send an email to the other party, he found that the email could no longer be sent.

Lao Ma smiled slyly, "Sly guy," then he flattened his lips in his signature way and said, "Same as me."

Musk naturally went to decrypt the other string.

"Bastard! You are such a cunning fellow."

Musk said this because the way of communication between the two people proposed by Lin Yuan was really... against the will of heaven.

The essence of communication is to let the other party see what you send.

For safety reasons, Lin Yuan just sent money and didn't want to receive any.

Because emails can be sent at any time, the server can be set up and then crashed after the emails are sent.

But receiving emails is not possible.

Just like just now, in order to receive Musk's reply, even though the time was very short, it still lasted about three minutes.

It only takes less than three seconds to send. You only need to prepare the server and connect it to the line for three seconds. Once the sending is completed, the machine can be crashed with one click.

Just like when you send a text message to someone, you can pull out the card and smash the phone within seconds after sending it.

If you receive text messages from others, you have to wait.

So much of this world is caused by waiting to go wrong.

So, Lin Yuan didn't want to wait.

Therefore, Lin Yuan came up with an incredible idea - asking Musk to publish the encrypted string publicly on the social platform.

It’s useless even if the whole world sees it, because only Lin Yuan, who has private key B, can decrypt it.

At this moment, no money or power in the world can defeat the private key B in Lin Yuan's hand, which represents technology.

Technology has always been king!
Money and power can only crawl at its feet.

This is because people are attracted by money and power and have formed too many illusions.

[Bro, if you were a biological woman, I would definitely have a child with you.]

Fortunately, Lin Yuan didn’t know about Musk’s idea.
