The Cheshire Cat, can take any shape he wants and was generally available to guide Alice in wonderland. Can't help but think that has something to do with it. Looks like he has shaped himself into a doormat or something. When he disappears, only his smile remains.

Common man/girl, let me shut this PC off and go to bed.....
Yes the Cat can disappear and " You cannot attack what you do not see" Wink

Now seriously, goodnight bro/sis

If there's a weakness to my theory, I think it's that 45 bits doesn't give much brute force resistance.

Trying to bruteforce 7zip would take a LOT longer than bruteforcing a bitcoin key.

I think she wants us to use bits 7-51 of some SHA hash.

.. or bytes 7-51, but this is a bit unlikely. You can not predict the result of the SHA function, it would be like using the random numbers.

Other question is which exact of the many SHA functions?

She wouldn't have to predict the hash. She could use any string for that password. She doesn't have to know it in advance.

Which SHA function? I'd assume 1 (the first commonly referred to as "SHA") or 2 (the 256 bit variety used by Bitcoin).

If there's a weakness to my theory, I think it's that 45 bits doesn't give much brute force resistance.

Guys and girls, sorry I am out.
It's nearing 3 AM here and really I can't think properly anymore - as if I could before Grin

Seriously I am off to bed and start calling Alice names because I can't sleep because I will keep thinking about this. Undecided

Alice, I hate you - and I love you (but not in a physical way, you know what I mean)

So guys sorry, I know I didn't add much today and there won't be any more additions from me *tonight*.

I will check back in a few hours after I get some shut eye......

Love you guys Kiss

Goodnight

and minecraft ( I think)

Contra is 8-bit, as are all NES games. Minecraft most definitely is not.

I made an error. A bit is 1. A byte is 8. Original post edited.

S4VV4S: it might not be irrelevant. I was just pondering that myself.

there's another prime number: 1039 (the height of the image). the other two images both had a 3:2 aspect radio whereas this one isn't.

the size of the 7z file is also prime number 1.91mb - 191 is prime number.

I wonder if the content (probably another image) has the same values.....
