==== Creating keys manually ====
 
In older versions of Alpine, we had to manually create keys for signing packages and indexes. This explains how. Nowadays you can just use <code>abuild-keygen</code>.
 
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:
{{cmd|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}}
 
Create the public key:
{{cmd|openssl rsa -in ''emailaddress.priv'' -pubout -out /etc/apk/keys/''emailaddress''}}
 
The public key should be distributed and installed into {{Path|/etc/apk/keys}} on the alpine box that will install the packages.  The private key, when created by <code>abuild</code>, is installed into {{Path|~/.abuild/$something.rsa}}. This basically means that the main developer's public keys should be in {{Path|/etc/apk/keys}} on all Alpine boxes.

For abuild a public/private rsa key pair is needed. The abuild-keygen command from abuild package generates and configures the security keys.

$ abuild-keygen -a -i
