Getting your hardware and software ready
What you will need:
- air-gapped computer (not connected to the internet)
- networked smartphone
You will need to install the following into your air-gapped computer:
- keysmith
- keysmith
- You will use this generate important artifacts like `seed phrase` and `private key`s
- openSSSL
- [1](https://wiki.openssl.org/index.php/Binaries)
- required by quill`
- quill
- [2](https://github.com/dfinity/quill) - you will use this to craft messages like "create neuron" for the Internet Computer - You can install it by downloading the binary for your operating system or by cloning and compiling the code - note that once installed, the command to execute is `target/release/quill`
- `qrencode`
- https://github.com/fukuchi/libqrencode) - [3](https://github.com/fukuchi/libqrencode) - Generates QR codes for bridging the air gap - Tip: if you have Homebrew, you can install via `brew install qrencode`
- `jq`
- [4](https://github.com/stedolan/jq) - Required for creating multiple QR codes - Tip: if you have Homebrew, you can install via `brew install jq`
- Copy and paste the following bash script into a file named `quill-qr.sh`:
Warning: Only tested on MacOSX and Linux.
```bash
- !/usr/bin/env bash
URL=https://p5deo-6aaaa-aaaab-aaaxq-cai.raw.ic0.app IFS=$'\n' read -r -d -a messages < <( cat - | jq -M 'if . | type != "array" then [.] else . end' | jq -rcM .[] && printf '\0' )
for message in "${messages[@]}" do
echo "$URL/?msg=$(echo "$message" | gzip -c | base64 | tr -d '\n' | sed -e 's/+/%2B/g' -e 's/\//%2F/g' -e 's/=/%3D/g')" | qrencode > qr.png open qr.png echo ENTER TO CONTINUE... read < /dev/tty clear
done ```
Because an air-gapped computer is not connected to the internet, it can be a bit awkward to install these. The most common way to do it is to download them to a networked computer and transfer the files to the air-gapped computer via CD or USB drive. Others install these on a networked computer *and then* air-gap it.
