Poland directs officials to ditch Signal in favor of 'secure' state-developed alternative
(www.theregister.com)
This is a most excellent place for technology news and articles.
Agreed, but maybe for different reasons. Could you use Signal for government communication? Probably, but it would take intentional preparation, setup, and training of the end-users (most of whom are likely not security-minded or tech-savvy).
But practically speaking, governments should reasonably be developing an option that uses their own servers as relays, not ones controlled by a third party. Signal is run by a nonprofit (i.e. not driven by moneyed interests) and has survived court subpoenas for user data (because of how the useful data is stored encrypted at the endpoints, not the relays), but they do not have the same interests in nor are they developing a platform to keep government secrets safe.
Also, it's a central point of failure; even if it remains entirely uncracked throughout its lifetime, if the company goes under, those server relays will go, too.
I feel pretty safe as an end-user nobody, but I would be thinking twice if I was a government official.
