Reverse Keyword Cipher is a combination of a Transposition Cipher and Substitution Cipher. Basically this cipher can be used as a medium to distort a message you want to conceal.

E.g.

The Keyword is "Television"

In Reverse Keyword, you've just simply reverse the keyword itself.

Television → Noisivelet

Then like an Atbash you will substite both of them.

T - N
E - O
L - I
E - S
V - I
I - V
S - E
I - L
O - E
N - T

How to use it?

We need a plaintext.

E.g.

Our plaintext is LOTION
Keyword is "Television"

Plaintext: LOTION
Cipher text: IENVLET

Note: if the letter has two or more possible substition, you can use them as you want.

Like in the "Television" keyword

"I" has two possible substitute, V and L.

You can use them both as VL or LV, or choose one of them V or L.

Lotion → IENVEL or IENLET or IENVLET.

Well it's up to you.

*kung walang makitang maisa-substitute sa plaintext to keyword

E.g.

Plaintext is MOTION
KEYWORD IS TELEVISION
MOTION → MENLET

THE LETTER OR CHARACTER WILL REMAINS THE SAME.
