   I am far from not having to say more about it. Most people who 
provide signatures store their private key on a machine also used for 
web browsing. I know this also applies to Debian because keeping the key 
secure or at best offline would require some considerable provisions and 
AFAIK none of you have implemented a separation of concerns i.e. one 
computer for browsing and another one for secure ssh connections.
   That would be required though to keep the secret key safe. We have an 
arbitrary code execution bug in browsers every few month and that does 
not count all the zero day exploits at all. Sites in the www are 
commonly spoofed by secret services. Even the Snowden revelations do 
tell (operation Quantum insert). That way the secret key is guaranteed 
to be compromised a few milliseconds after its creation. The NSA also 
has its own key stealing programme. I wanna tell you that you are better 
off checking the SHA512SUM. That one, as soon as you have retrieved a 
genuine one, can no more be spoofed.
   Besides this it is a common attack vector to infect computers via 
online updates. Once more they need to know the secret key in order to 
do so!
