Let's crack Sloot algorithm - infinite "compression"

[WhatIsIt]

Movie or file is series of numbers merged

123456789123456789123456789

Now you look into table and write coordinates

5
55
2
78
34
26

We know that first number is begin,
second number is end,
so you read coordinates in pairs of 2.

5, 55 = 12345
2, 78 = 678912345
34, 26 = 6789123456789

and merge sequence together again

123456789123456789123456789

and write it back into memory as it was at first place, in sequence.


So, number of coordinates are telling us how much sequence is long.

When there are no coordinates we are done, and vice versa.


No delimiter.

another detail worth mentionig is encoding side could do a lot of computation to find input variables that yield most matches for a particular file, so random is not really random but customized random.

No delimiter.

and how did you imagine using 1 digit coordinate, it cannot be 555, only 0555, otherwise coordinates would get mixed up.

as for spacer, again, coordinates are produced in different iterations, from different sets of random numbers, algorithm MUST know which iteration produced which coordinates, so spacer is needed

[WhatIsIt]

The problem is because we think in decimal which is not suited for binary and numbers dont match.

We can write byte 255, but can not 999, because byte can not hold it.

Lets say that coordinates are max 2 numbers, 00 - 99 and you write it that way.

You have table 100 * 100,

6 coordinates are 12 numbers.

If we can write with 12 numbers 25 numbers, then the thing will work,

otherwise, hmm?

[WhatIsIt]

Yes, it must be 05, 55 and not 5, 55.

And we spend more memory, but delimiter is not needed.

Delimiter will be very hard to implement, if we dont know exact length of sequence.
