# Multi Factor Encryption?

I got an alert last night to the keywords above and was curious, so took a look at the tor site flagged which is the following one:
http://nsrz5iogimqwgeax3clpp6hvfy6viom2woy7dghgxes4sqk63r7svoqd.onion. Obviously you need TOR to access it or a service like Tor2Web though reachability is spotty.

I'm asking SE because these guys are claiming to offer a cipher strength I've never heard of. I'd like to ask if you think it's even possible.

This question is about the encryption scheme "Blobby" presented on their site and the security claims surrounding it.

The first notation they use is $$10^{yM}$$ which I didn't get, but just below is an example $$10^{41485806}$$, which seems obscene with the unit to of the previous number being "operations", which can be inferred from them stating a relative strength of $$10^{38}$$ for AES-128 which is roughly $$2^{128}$$.

Now that I've have longer to look at it, it feels less impossible (though still a stretch), I think the key size and password length are important, but I suspect they're using a third mutagen.

The key claim of novelty for this encryption scheme is that both a nearly-arbitrary sized password (20-$$2^{12}$$ chars) and an arbitrary sized key ($$2^{16}$$-$$\infty$$ bit) are necessary for symmetric operation yielding "multi-factor security" with their custom encryption scheme. The precise quote is

Blobby is fundamentally different, the password is used in conjunction with the key, meaning that each is useless without the other, and attacking the key's password won't get you any closer to the message password.

If their claim is solid, would this be quantum resistant?

I have now downloaded the 3 sample files and looked at them, they are clearly encrypted. I've been trying the first sample for over 24hours now with not a whisper of joy.
