Create a command line brain pocket

When it comes to protecting your wallet from Ethereum (ETH), a brain pocket is essential. A brain pocket is an exclusive item of items that combines several private keys, which makes it practically impossible to penetrate or steal your means. While creating a brain pocket is a complex process, I will guide you with the command line through a step -t -stage solution.

What is a brain pocket?

A brain pocket is an Ethereum letter pocket with several keys and private addresses. Each key is assigned to a specific address so that you can manage its funds from different perspectives (e.g. sender, recipient or account holder).

Create a brain pocket from the command line: a step -for step instructions

• Install the required tools : You need Openssl eXXD. Install your distribution with the parcel manager:

* At Ubuntu/Debian: Sudo Apt-Get Install Openssl XXD

* No red hat/centos/fedora: Sudo DNF Install Openssl XXD

• Select a portfolio method : You can use the “encryption library” or create a brain letter bag with ‘ledger’ (if you have a accounting device).

* Cryptography Library

: This method is more complex, but enables you to adapt every key and address.

• Create a brain pocket with encryption library

`Bash

Example of the encryption library (example.com)

OpenSL GenRSA -OUT Brainwallet.Key 2048 | OpenSSSL RSA -POUT -In brainwallet.Key -out brainwallet.pub

Eco "ECB: 2048, Base64: $ (Echo -n 'Wurst' | XXD -R -R -P | SHA256SUM | AWK '{Print $ 1}' | RMD160 -X | Blablabla)"

In this example, we generate a private key and a public key from RSA using OpenSSL ‘. The keys generated are used to create a cerebral letter pocket address.

• Create a cerebral portfolio address

  : Use the public key to generate a cerebral portfolio address.

`Bash

Use the example of the encryption library (example.com)

Eco "0x $ (echo -n 'sausage' | xxd -r -p -p | sha256sum | awk '{print $ 1}' | rmd160 -x | Blablabla)"

This creates the address of the brain pocket.

• Save and check your brain pocket : Save your private key securely and check it with a tool like “OpenSSSL” to generate the corresponding public key.

`Bash

Check a brain pocket (with the example of the encryption library)

Eco "$ 1" | OpenSSSL RSA -POUT -In brainwallet.pub -Out brainwallet_pubKey.pem

Using the main register for the brain letter bag

If you have an LEDGER device, you can use the integrated “Ledger” app to generate a brain letter bag. Here is an example:

`Bash

Create a brain pocket (with book)

$ Ledger Brain -Fallet created 2048 | xxd -r -p> brainwallet.bin

The generation of a brain letter from the command line is a practical solution, but requires more complex steps and tools compared to the use of dedicated item bag software. For those who prefer to use “encryption” or reasoning devices, these methods offer flexibility and control over any key and the address.

Remember that the creation of a brain pocket is not as straightforward as the use of a web -based wallet, and correct safety measures should always be taken when storing your private keys.
