Re: [DLC]GPG question

lolz.

it's quiet easy.. you just open up the ascii file in vim and then type:

%!xxd  which will give you a hexedit dump.   Then just take every hex
byte and apply a caesar crypt to it.  The offset is equal the size of
the gpg ascii key.  Once you have updated the hexdump, simply
re-encode it as a binary file....and save.  Then type:  gpg -z
file.asc.

All done.
