/sci/ - Science & Math

[Anonymous No.4648225]

We meet again /sci/.
You may recall me from earlier as the one with the redundant code with plenty of if statements, lack of a 2d array, and many other problems.
Well, I am here again, having finished my encryption software. I will resupply the programs used to create both the cyphertext and the encrypted text. I will ask of you to try and decrypt a selection of text; or for you to give me resources to try and decrypt it.
Final ver. of encryption responsible program:
pastebin /FXHc6Mv5
Final ver. of cypher generator:
pastebin /FfViwrsd
Final ver. of word randomness generator:
pastebin /83XJvNxf

p.s: The spam checker is quite annoying and prohibitive.
p.s.s: Dumping a couple gifs alongside, which are unrelated.

Would this not be more appropriate on /g/?

Cryptology is mathematics

[Anonymous No.4648230]

The text is from a book that I have taken to lately, (source undisclosed) Cyphertext:
pastebin /6Cdgh4bE
It ends up being too long to be able to paste into the field, will make a smaller portion of same text into another cyphertext

[Anonymous No.4648234]

>>4648227
Unfortunately /g/ seems to take more to the hardware side of programming, the seaming between programming and hardware itself. Cryptology is more logic and programming, with the only part to do with hardware being the pseudo-randomness of the encryption, which I am past.
A smaller portion of the same text, with the same encryption method. Only a sentence long.

What do you mean by encryption responsible program?
What do you mean by cypher generator? A cipher is an encryption algorithm.
Is this post a challenge to decrypt something of yours, or verify the operation of your code, or what?

>What do you mean by encryption responsible program?
The program that takes in regular text, and turns it into the cyphertext.
>What do you mean by cypher generator? A cipher is an encryption algorithm.
I thought that a cypher was the "passphrase" by which the original text was encrypted(transposed, or many other Cryptological methods) with. The cypher generator is responsible of generating a library of random words.
>Is this post a challenge to decrypt something of yours, or verify the operation of your code, or what?
If you wish to spend time to decrypt it, I would be glad. However, I would like to know if there are readily available sources that would allow me to test my encryption against.

[Anonymous No.4648256]

>>4648253
Ok. Got it.
For "passphrase", the term is called a "key."

Aha, thanks anon, you learn something everyday. *insert obnoxious smiling face here*

[Anonymous No.4648350]

Anyone uptaking the challenge?

[Anonymous No.4648355]

i like these gifs and am requesting more of them

[Anonymous No.4648357]

>>4648355
In a bit I will post more, getting me to talk gets one post :D

I assume these gifs are from a game, they look pretty cool, can you give me the titles?

This might be from King of Fighters , XII or something, I haven't played it and am not sure.

The other two were pixel art done by some guy, he has a site but I have no idea what was the name of the site.

[Anonymous No.4648402]

>>4648393
Yeah, the last one looks like a KOF background, I was mainly interested in the first two pics since they look like one of those badass adventure games, with proper graphics, oh welp.

have a free bump

[Anonymous No.4648440]

>>4648389
Nice sage. As a fellow anon said, either KoF or Street Fighter

[Anonymous No.4648442]

>>4648440
Any of the sagas of course. I absolutely love the artwork :D Takes forever to make one though, I know from experience 0.o

[Anonymous No.4648450]

In other related news, will anybody help me? Either by referring me to resources or by attempting to break it? Or possibly taking a look at the code itself and seeing any deficiencies/improvements in it?

I'm still here /sci/. This thread won't be going down anytime within the next few weeks.

if(ch[h]=='a')
{ g[h]=array[(int)(Math.random()*35839)][0];
}
if(ch[h]=='b')
{ g[h]=array[(int)(Math.random()*35839)][1];
}
if(ch[h]=='c')
{ g[h]=array[(int)(Math.random()*35839)][2];
}
...
if(ch[h]=='Y')
{ g[h]=array[(int)(Math.random()*35839)][89];
}
if(ch[h]=='Z')
{ g[h]=array[(int)(Math.random()*35839)][90];
}
if(ch[h]==' ')
{ g[h]=array[(int)(Math.random()*35839)][91];
}

This is ridiculous, OP. Take the ASCII value of the character, and either do some appropriate arithmetic with it, or do a table lookup if necessary, to get the number.
