From Whonix
Install signify-openbsd qrencode.
1. Update the package lists.
sudo apt-get update
2. Upgrade the system.
sudo apt-get dist-upgrade
3. Install the signify-openbsd qrencode package.
sudo apt-get install signify-openbsd qrencode
The procedure of installing signify-openbsd qrencode is complete.
Create key. Needs to be done only once. Unless desired to use multiple keys, in which case different key names should be used. In the following example, keyname is used as example key name.
signify-openbsd -G -p keyname.pub -s keyname.sec
Alternatively add a key comment. Replace comments here with the actual comment but keep the ". Comment could be a name, position, website, e-mail address and/or anything else.
signify-openbsd -G -p keyname.pub -s keyname.sec -c "comments here"
The private key file keyname.sec needs to stay private, i.e. never share keyname.sec with anyone as this would defeat the purpose of signing files!
The public key file keyname.pub can be shared with anyone.
To sign a file message.txt (which has to be created by the user beforehand).
signify-openbsd -S -s keyname.sec -m message.txt
Will create a signature file message.txt.sig.
To verify a file message.txt with signature file message.txt.sig.
signify-openbsd -V -p keyname.pub -m message.txt
Optional. To create a QR code for the public key.
qrencode -r keyname.pub -o keyname.pub.png
File keyname.pub.png would be the QR code of the public key.
