I don't know the tools that decrypt stuff like that, but I would have to
agree with Dave. It makes more sense to me that they would have to decrypt
the last run encryption before they can work on the first encryption.
Although I can understand that the programs they use probably automatically
start decrypting next level after each level completes, so that could be
considered one step. In other words, clicking decrypt button once could do
however many levels of encryption that was done, one after another. So,
that wouldn't save time, but you click it and wait however many
hours/days/weeks/months it takes to decrypt.

I understand your points; I think that you may be missing mine.
Consider the following plaintext
All Good Men Come to the Aide of their county.
One encryption program converts this to:
ASDWEWSER$#$sdrff33SDRF#$34#$
The second encryption program converts that text into:
23D#@$8878734SDR*E&R*E*))))))3423&SDF^&F^
My question really comes down to:
Does someone have to decrypt the 2d string of encrypted data into the first
string and then convert the 1st string into plaintext OR
Can systems take the second string and IMMEDIATELY convert it into
plaintext?
It would seem reasonable that the former would have to be the case b/c their
isn't (I don't think) a one-to-one correspondence of the data at each level
of the encryption, that is, if one were to take, as an example, a CODE, and
then convert into into a CIPHER, you'd have to know both in order to figure
out the original plaintext (this is my analogy).
Consider the following plaintext:
The enemy is coming from the east this coming Monday.
I use a code manual to represent this plaintext as:
My waiter has a horrible cold.
I then use a cipher to convert that code into:
JQMNO R4DJ9 3DJLD 34ADJE 9SALE DSTUV
It seems like you would have to break level 1 independently, then break
level 2
However, I'm told that the way that codebreaking with computers work, a
multi-level encryption can be broken in one step. That just seems crazy to
me.
