How to Make Your Computer Ultra Secure with Encryption & Tor

With great power comes great responsibility.

With great power comes great responsibility

Bitcoin has the world’s most secure network, and there are literally billions of dollars worth of Bitcoins waiting for those who are capable of hacking the protocol. However, this task isn’t as simple, since Bitcoin is composed of something called SHA256. SHA which stands for Secure Hash Algorithm, is a cryptographic hash function with military-grade encryption, and the odds of cracking a private key are next to zero.

With Bitcoin, security breaches do not actually happen on the protocol itself, but because of the carelessness of the third parties.

Bitcoin and other cryptocurrencies are putting the financial power back to the hands of the individual. This power requires a high degree of personal responsibility and awareness.

This means that the individual is forced to be aware of their own possessions as they are personally 100% responsible to protect their own private keys.

How To Make Your Computer Ultra Secure.

1. To make your computer ultra-secure, we will first have to get rid of the biggest virus in the world: Windows.

2. We will then replace this virus, with a free fully encrypted Linux based open-source operating system, such as Ubuntu.

3. On top of this, we will anonymize your whole computer by routing all the network traffic through Tor. We will accomplish this using an open-source program called Anonsurf. This way whenever you connect to the internet, whether you are using a wallet, browser or any other application, you are completely anonymous and hidden from malicious hackers.

Why Linux is more secure than other operating systems?

Linux is not just a random operating system, in fact, it’s the world’s most popular choice when it comes to servers, basically, our whole internet runs on Linux, while the average joe is still stuck with the Windows. We will not go too deep on describing why exactly Linux is considered far more secure than Windows or Mac. But here are a few obvious reasons.

1. Open Source

Linux is an open operating system, the code which can be read by everyone is also maintained by a large audience.

2. Architecture

Linux operates in many different environments, it’s architecture is more complex that in windows. Due to its different consoles, packages, and multilevel component arrangements, it’s more difficult for viruses to access the system files.

3. Administrator rights

Windows users have by default administrator rights to access everything in the system. If a virus penetrates through the system, it can quickly access it’s most important parts. In Linux, users have lower access rights, and in theory, viruses can only touch local files and folders, while the system remains safe.

Why we need privacy and how can Anonsurf help?

Some people might wonder why privacy important in the first place? Well, the core answer to this is very simple, see it’s not as much about hiding something, but the fact that if you don’t have privacy, you don’t have the ability to speak. And money by in itself is actually a language that we all speak when you buy something with your dollars or Bitcoins, you are creating a vote.

There are many reasons why someone involved with cryptocurrencies prefers to stay anonymous, whether you wanna transact without being watched, or just simply want protection from other hackers. After all, privacy is a human right, and there should be no need for an explanation if someone prefers such.

What is Anonsurf and how does it work?

Anonusrf is an open-source project which uses TOR iptables to anonymize the whole system. Anonsurf gives users full control over their network, by having the ability to either starting or stopping the l2p project. This way user can freely do experiments in Linux running anonsurf in the background. You can, for example, run a wallet app, browser, or any other application without leaving any traces of your real IP address. Anonsurf repository consists of both Anonsurf and Pandora packages. Pandora overwrites the RAM when the user shuts down the computer and also clears the cache. That means it also wipes all traces of the user’s work from the system. This can be run both automatically and manually.

What about VPN, you might ask?

The thing with VPN is that the operator can read you like an open book, everything you do is very clear and visible to them. And if you happen to run VPN on top of TOR, even then if you by one way or another connect your name to the VPN provider, your data is in no way hidden, it’s more of just protection against hackers at that point going forward. However there is a place for VPN as well, for example, it can be an extremely powerful tool on top of TOR especially if you have not yet revealed your real identity to the internet by behavior.

Getting Started.

To get started with this project, we suggest you obtain another laptop or pc which you can then play around in case something goes wrong. In practice, it also makes sense to have a separate machine that is specifically designed for handling cryptocurrencies only. After you get a hang of Linux, you may want to which it to your main operating system.

Steps to make your computer ultra-secure.

  1. Download the Ubuntu ISO file.
  2. Make a bootable USB.
  3. Boot from the USB.

You can test it right away by opening firefox and typing “what is my ip” on duckduckgo, like this.

what is my ip

Or you may use websites that show your external IP, such as www.ipleak.net

Note: Sometimes the connection doesn’t pick right after starting anonsurf, if this happens to you. Try stopping it by typing sudo anonsurf stop, then go and test if you can connect normally to the internet, if so try to start it again, and see if it works.

Alternatively, you can also try typing: sudo anonsurf restart

You can also change the tor identity whenever you want, by typing: sudo anonsurf change

Other useful commands can be found simply typing: anonsurf on a terminal.

Remember, the program must always be used under Root privileges, meaning you will have to type “sudo” and hit your password whenever you try to change your network settings.

That being said, your computer is now officially one of the most ultra-secure ones in town.
