This document describes how to create a public and a private key for signing of packages and indexes. The public key should be distributed and installed into /etc/apk/keys on the alpine box that will install the packages. This basically means that the main developers public keys should be in /etc/apk/keys on all alpine boxes.

Since the public key needs to be unique for each developer the email address should be used as name for the public key.

Create the private key

openssl genrsa -out emailaddress.priv 2048

Tip: Append -aes256 if you want it encrypted, but then you'll need to enter the password for every package you sign

Creating the public key

openssl rsa -in emailaddress.priv -pubout -out /etc/apk/keys/emailaddress
