1. Phillips Cipher encoder

Text : ABCD efghi
Alphabet25 : key
Shift Row / Column : Shift Row

Solution:

The Phillips cipher is based on a Polybius square whose rows, columns are reordered to form 8 different grids. The plaintext is divided in groups of 5 letters and then enciphered using each grid.

Alphabet = keyabcdfghilmnopqrstuvwxz

Grid-1 :

\	1	2	3	4	5
1	k	e	y	a	b
2	c	d	f	g	h
3	i	l	m	n	o
4	p	q	r	s	t
5	u	v	w	x	z

Grid-2 :

\	1	2	3	4	5
2	c	d	f	g	h
1	k	e	y	a	b
3	i	l	m	n	o
4	p	q	r	s	t
5	u	v	w	x	z

Grid-3 :

\	1	2	3	4	5
2	c	d	f	g	h
3	i	l	m	n	o
1	k	e	y	a	b
4	p	q	r	s	t
5	u	v	w	x	z

Grid-4 :

\	1	2	3	4	5
2	c	d	f	g	h
3	i	l	m	n	o
4	p	q	r	s	t
1	k	e	y	a	b
5	u	v	w	x	z

Grid-5 :

\	1	2	3	4	5
2	c	d	f	g	h
3	i	l	m	n	o
4	p	q	r	s	t
5	u	v	w	x	z
1	k	e	y	a	b

Grid-6 :

\	1	2	3	4	5
3	i	l	m	n	o
2	c	d	f	g	h
4	p	q	r	s	t
5	u	v	w	x	z
1	k	e	y	a	b

Grid-7 :

\	1	2	3	4	5
3	i	l	m	n	o
4	p	q	r	s	t
2	c	d	f	g	h
5	u	v	w	x	z
1	k	e	y	a	b

Grid-8 :

\	1	2	3	4	5
3	i	l	m	n	o
4	p	q	r	s	t
5	u	v	w	x	z
2	c	d	f	g	h
1	k	e	y	a	b

The plaintext is first divided into blocks of 5 letters.
Block-1 is enciphered using Grid-1, Block-2 using Grid-2, ..., Block-9 again using Grid-1, so on.
Each plaintext letter is located and then enciphered by the letter diagonally below and to the right in the grid.
If a plaintext letter is at last row then use the first row and if at last column then use first column

Each char and each code

Block	#1	#2
Grid	#1	#2
Ciphertext	abcde	fghi
Plaintext	hclmf	abkq

So finally

Plaintext	: abcdefghi
Ciphertext	: hclmfabkq
