Simple Offline Wallet (key-pair) Setup on Linux Without GUI

Background: So, I made this simple BASH paper wallet generator called BASH21. Just yesterday, I was curious about the easiest way to create a paper wallet on a Linux machine that doesn’t have a graphical interface. Prerequisites: 1. Any Linux machine that’s offline. 2. A computer with internet access. 3. A USB drive. Preparation: 1. On your internet-connected computer, grab the libbitcoin-explorer from here: https://github.com/libbitcoin/libbitcoin-explorer/releases/download/v2.2.0/bx-linux-x64-mainnet. Sure, you can compile it yourself, but that’s not the simplest route. I also think it’s important to verify the binary file. 2. Transfer the binary to your USB drive. 3. Boot up your offline Linux machine and plug in the USB. 4. Open a terminal window. 5. Mount the USB drive. You should see something like this: So now we need to mount the USB from /dev/sdb1 to a mount-point in our file system. Let’s set up the mount-point and get the USB mounted there. 6. Copy the binary from the USB to your file system, let’s say to ~/easy-paper/. We’ll also rename it just to bx. 7. Set it to be executable. Actual Wallet Creation: The output will look like this:
