Some British politicians arent keen on members of the public encrypting their communications, because of the difficulties that law enforcement and intelligence services can experience trying to snoop upon you. The answer is to use VPN (Virtual Private Network) software that creates a secure encrypted tunnel, allowing you to access the internet privately when using a public connection. If VPNs were forced by Parliament to have a backdoor that could be used by the intelligence services to spy on you, well, that could also be handy for criminals too.”]
