The class GetPublicKeys offer several small methods to write a line like

command="getcredentials",from="server.domain.tld",no-port-forwarding,no-x11-forwarding,no-agent-forwarding ssh-rsa ... Zemke-Rhyne

This line is divided in four parts:

• the SSH options
• the key algo (e.g. ssh-rsa)
• the SSH public key itself (here truncated to ...)
• a comment

Instead of functions with a focus to write text, it could be more flexible to create an AuthorizedKeysLine class, with:

• booleans to enable or disable options like no-x11-forwarding, matching man 5 authorized_keys
• arrays of string to fill from
• a __toString() method to get the string representation of the line

This will allow to reuse this class in more deployment scripts.
