The following example uses /var/www/html/repository as the location of the primary package repository. Presumably there are sufficient privileges to create this new directory:

gpg --init primary /var/www/html/repository pgpkeys.txt

pgpkeys.txt is the output file from gpg --export --armor. The directory /var/www/html/repository is presumably published by a web server as http://www.example.com/repository. A relatively modern HTTP 1.1 server, such as the current version of Apache, gives the best results.
