[TuT] How to manually decrypt ROT-5 & 18 Hash [TuT] by 3x0r

This tutorial is for those who don't know about ROT if you know it don't bother reading.
PS : The Points (.) are for spacing

Introduction

Some people send ROT type of emails to confuse unwanted readers thinking it's a mysterious language.
Same with some hackers want to communicate without knowing others what they are talking about.
It has been evolved in mid-1992 as a response to postings repeating urban myths on alt.folklore.urban, after some posters complained that "Sheesh!" as a response to newcomers was being overused.

So lets us start:

ROT-5 is the easiest Hash to crypt and also easier to decrypt
What to do is writing from 0 to 9 and in the half make some spaces
0 1 2 3 4..5 6 7 8 9

Then put under what you wrote from 5 to 9 then from 0 to 4
0 1 2 3 4..5 6 7 8 9
5 6 7 8 9..0 1 2 3 4
You check the character of the word and you write the Numbers under it
9 = 4
1 = 6
6 = 1
6 = 1
8 = 3
1 = 6
0 = 5
5 = 0
7 = 2
2 = 7
so we get 4611365027 when it was 9166810572

Check How to Decrypt ROT-13 here https://hackforums.net/showthread.php?tid=466356

After you Checked it you may continue to ROT-18

ROT-18:

Well ROT-18 is just combining ROT-5 With ROT-13 they figured the name out by adding 5 to 13 ...

ROT-5 Table :

0 1 2 3 4..5 6 7 8 9
5 6 7 8 9..0 1 2 3 4

ROT-13 Table :

a b c d e f g h i. j .k l m..n o p q r s t u v w x y z
n o p q r s t u v w x y z..a b c d e f g h i. j .k l m

Let's Say we have Leb961 to encrypt / decrypt

L = y
E = r
B = o
9 = 4
6 = 1
1 = 6

So we get YRO416 when it was LEB961

Yeah, I've seen people thinking ROT was some insane cryptography. I had no idea it's actually used for passwords. ROT 13 is the most popular rotation encryption.

Yeah but no one use it for passwords anymore ... well i personally use it for sending secret mails and sms ... that's what it should be used for
actually rot is preaty basic to decrypt you just need to know the rot its on. thx the tuts
