STDOUT? STDERR?

i noticed that gpg can send output to the terminal, apparently bypassing 
STDOUT and STDERR...

i would expect this command to not send any output to the terminal:
 	$ date | gpg -ear {untrusted_key} > /dev/null 2> /dev/null

but it sends quite a bit of information to the terminal...?

how is that done?
why is it done that way?
how can that info be collected and/or redirected by the shell?

thanks...
