 Review comment:
   oh boy I'm not so sure about this one; if the SSL logic in `common.sh` and `common_ssl.sh`
is coupled like I'd rather have them in the same file. I believe so far we managed to keep
the `*common*` relatively independent and I'd like to retain that. At the very least the modified
variables in `common.sh` should have a comment that they may be modified from `common_ssl.sh`
