Why? Wrapping a key with itself is pointless. It's like buying dehydrated water: just add water to reconstitute. You need the key key1
to decrypt wrap1
-- and then what do you get back? You get back key1
, which is what you already had.
Of course, someone who doesn't have the key (and can't guess it) cannot decrypt the wrapped key. That's how key wrapping works. So, no, given just wrap1
or just wrap2
, you cannot deduce the value of key1
.
