Files dumped from the socket are put in a temporary directory, this
directory is then removed upon exit.
Variable were cleaned to be clearer:
- crt_filename -> prev_crt
- key_filename -> prev_key
- ${crt_filename}.${tmp} -> new_crt
- ${key_filename}.${tmp} -> new_key
Compare the fingerprint of the leaf certificate to the previous file to
check if it needs to be updated or not
Also skip the check if no file is on the disk.
haproxy-dump0-certs is a bash script that connects to your master socket
or your stat socket in order to dump certificates from haproxy memory to
the corresponding files.
