You should be able to decrypt this.
|
||||||
|
|
||||||
|
Alright, well, all of these values are 7-bit (none of the first nybbles of the
|
||||||
|
given bytes exceed 0b0111). Do you see a pattern? It's easier because of my
|
||||||
|
blah formatting. Every cut-off line starts back in on 0x2 (0b0010), 0xA
|
||||||
|
(0b1010), or 0xB (0b1011). Every third byte of a line alternates between 0x64
|
||||||
|
(0b 0110 0100), 0x22 (0b 0010 0010), and 0x00 (all zeroes). So this sequence is
|
||||||
|
patterned in some way. Because the key is a single byte I assume this is some
|
||||||
|
sort of Caesar cypher esque secret [op] key = clear so let's start with that.
|
||||||
|
|
||||||
|
The key is 0x2A. Because it's summer and 4chan this is probably simple so let's
|
||||||
|
start with low hanging fruit.
|
||||||
|
|
||||||
|
$ ascii 2a
|
||||||
|
ASCII 2/10 is decimal 042, hex 2a, octal 052, bits 00101010: prints as `*'
|
||||||
|
Official name: Asterisk
|
||||||
|
Other names: Star, Splat, Aster, Times, Gear, Dingle, Bug, Twinkle, Glob
|
||||||
|
|
||||||
|
0x64 XOR 0x2A = 'N'
|
||||||
|
0x22 XOR 0x2A = ASCII_LS1
|
||||||
|
|
||||||
|
I assume control characters besides usual whitespace won't be a part of the
|
||||||
|
input so it's not an XOR thing. Nor addition as bytes exceed 0x70 (and
|
||||||
|
therefore addition would put the values past valid ASCII). Nor subtraction as
|
||||||
|
0x00 occurs and that would underflow to either negative values (signed) or
|
||||||
|
values past 0x80 (unsigned), again, invalid ASCII.
|
||||||
|
|
||||||
|
I wanna see this better. I'm tossing the key line so remember it's 0x2A.

As cool as it is to actually /see/ the data this hasn't gotten us anywhere
|
||||||
|
closer to solving the riddle. By the way, this is my first time doing something
|
||||||
|
like this and I have entirely no clue what I'm doing. I think I'm barking up
|
||||||
|
the right tree because, ignoring addresses <0x20, every column has at most
|
||||||
|
three unique values.
|
||||||
|
|
||||||
|
I asked a roommate and it said it didn't know and asked why I was wasting my
|
||||||
|
time on /g/ riddles.
|
||||||
|
|
||||||
|
The message length is 140d bytes but the encrypted length is 0xE0 (224d) bytes.
|
||||||
|
The first two rows don't fit the pattern so perhaps they're a 32d byte header.
|
||||||
|
That would be 192d bytes for a 140d byte message?
|
||||||
|
|
||||||
|
Does this repeat?

Hm. I'm a little stumped. I went back to the thread and checked for clues. One
|
||||||
|
anon XORed and gave up and the others are discussing whether trans people
|
||||||
|
deserve to live. I hate summer vacation. All the small children have come off
|
||||||
|
/pol/ and are thirsty for blood.
|
||||||
|
|
||||||
|
0x2A is 0b 0010 1010. Maybe the alternating 01s is a clue. Actually, I don't
|
||||||
|
care anymore.

|
: 2 years of blahbbing
|
||||||
|
|
||||||
|
Today is Juneteenth and also the second anniversary of my blah. In the last two
|
||||||
|
years I went from being an 18 year old depressed burger serf who spent all her
|
||||||
|
time writing and programming deranged shit to being a 20 year old depressed
|
||||||
|
burger serf who spends all its time sleeping and working, but also on the other
|
||||||
|
side of the country and with some more friends now. Still, I am tired, and you
|
||||||
|
must forgive me if one day I give up on trying to get to the point where I
|
||||||
|
don't have to work so much.
|
||||||
|
|
||||||
|
I don't remember an awful lot of these last two years but I remember the
|
||||||
|
people. Usagi, M--, another person, and on-line Emma Tebibyte and the rest of
|
||||||
|
Tebibyte Media, Veronika, the administrators of murderu.us (and especially
|
||||||
|
suika who does basically all of the work on the server). Helping others is why
|
||||||
|
I keep going and I hope I've had some sort of positive impact. There are a lot
|
||||||
|
of people I miss.
|
||||||
|
|
||||||
|
My blah has been perused by hopefully less than two dozen people which makes it
|
||||||
|
special to me as a novel-length mostly nonsensical and often incoherent >700K
|
||||||
|
obscure Internet oddity that I have created. It hasn't been posted anywhere on
|
||||||
|
social media (though, feel free to share it on Hacker News, but anywhere more
|
||||||
|
popular is off limits) and even my close friends haven't read all of it. This
|
||||||
|
is indexed on DuckDuckGo which I should figure out how to prevent but not on
|
||||||
|
Google so hopefully I've not been violated in passing by corporate scraper
|
||||||
|
scum.
|
||||||
|
|
||||||
|
I don't have much more to say. I'm gonna start celebrating the blah anniversary
|
||||||
|
("celebrating") on 06-20 to avoid the collision with Juneteenth. Also happy
|
||||||
|
anniversary to the creation of X Windows. okbye
