[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
