Yeah you can.
Maybe something like this?
Code:
RewriteRule ^processor.php\?crypt=(.+)/?$ controller/method/processor/$1 [L]
You may also have to use RewriteCond %{QUERY_STRING}. I havn't used the RewriteCondition before so I have no idea how to carry it to the rule below.
Edit: make sure this rule is above all the other rules
