Rail fence Cipher Examples (encoder / decoder)

1. Rail fence Cipher encoder

Text : ABCD efghi
Number of Rail : 3
Offset : 0

Solution:

The rail fence cipher is a simple transposition cipher that encrypts plaintext by writing it in a zigzag pattern across N rows(rails) and reading it row by row

Write in Zigzag pattern across 3 rows(rails)

A							h
	B		D	e		g		i
		C			f

Read it row by row
A hBDegiCf

Plaintext	: ABCD efghi
NumRail	: 3
Offset	: 0
Ciphertext	: A hBDegiCf

2. Rail fence Cipher encoder

Text : hello world
Number of Rail : 3

The rail fence cipher is a simple transposition cipher that encrypts plaintext by writing it in a zigzag pattern across N rows(rails) and reading it row by row

Write in Zigzag pattern across 3 rows(rails)

h				o			r
	e		l			o		l
		l			w				d

Read it row by row
