What connectivity do I need to use the Signer?
Connectivity to use the signer:
https://signador.aoc.cat (default port 443)
https://nativa.aoclocal.cat (ports from 9090 to 9095)
Optionally if you sign with time stamps it would also be necessary to open connectivity to PSIS:
http://psis.catcert.net (default port 80)
