secret key

how can i protect my secret key?
if somebody take my pc he can easily by the command “export secet key” export this key to any support.
This key also is in the folder "documents setting/aplication data/gnupg.
It is dangerous if somebody has this key
Best regards.

Other people getting the secret key without
the password isn’t nice, but they can not
decrypt your messages or sign in your name.

Of course you should generally take care your
secret key is not taken.

And what about a removable flash disk? You can set your own directory for gnupg (–homedir [dir]) to eg. G:\mygnupg\ . You move your keys there and then you can remove your keys if you leave a computer. h
