→Koji Cert Components
* '''Koji Certificate Authority'''
* '''Koji Server Cert'''
* '''Koji Builder Cert'''
Together, these certs allow the builders to communicate with the koji hub and visa versa. After researching and a bit of tweaking, I managed to utilize a concept from Fedora Projects website (http://fedoraproject.org/wiki/Koji/ServerHowTo) and created a script which would make minimal effort for anyone making multiple certs, or for anyone who would rather quickly make a cert than learn the process. = How to use the script= I managed to break the code down into 2 separate pieces. One for making the CA (Certificate Authority) and one for making the certs for the different users/builders you would like configured. The way my script differs from the original is that it uses the variables passed to it as the default commonName in the ssl.cnf file.
For example, when executing my script to create a cert for a new user...lets say "kojiuser1":
#''./certscript kojiuser1''
The script as usual asks the various questions about where you are from and the OU name and the province etc, etc, but is then followed by the question of what the commonName should be. This name and/or the OU name should always be different from any other certs already created or you will get a TXT_ error. My script makes pressing enter easier by allowing you to press enter knowing that the commonName will be (by default).. "kojiuser1". Now this may not seem like anything huge for the creation of one user but what if we were creating multiple users (which was the case with me).
#''for user in arm{1..25}
>do
>./certscript $user
>done
''
In addition, a folder called "confs" holds all the conf files used to make the certs, this makes backtracking easier. For now only one line gets modified but it leaves progression for future endeavours. The only time you need to press a key other than enter is when it asks if you want to sign the cert. Of course 95% of the script remains the same as before but this modification makes life one step easier and hence minimizes the length of the cert creation process.
