Lesson 9: Scytale Code

SCYTALE CIPHER

Ang cipher naman na ito a transposition type of cipher. Suppose the rod allows one to write four letters around in a circle and five letters down the side of it. To decrypt, all one must do is wrap the leather strip around the rod and read across.
Take note you must make a table and insert there your input, table is based on diameter

Example message:HELP ME SOMEONE KIDNAPPED ME

Diameter 7=
|H|E|L|P|M|E|S|
|O|M|E|O|N|E|K|
| I |D|N|A|P|P|E|
|D|M|E|

Ciphertext:HOIDEMDML­ENEPOAMNPEEPSKE

SO BALE PARA MADECODE MO TO BIBILANGIN MO MUNA ILANG LETTERS FOR EXAMPLE YUNG BINIGAY KO NA ITO

HOIDEMDMLENEPOAMNPEE­PSKE

May 24 letters diyan
24÷7 = 3.5(ibigsabihin may tatlong lines na tig pito ang letters tas may isang line na di aabot ng pitong letters so ibigsabihin gagawa ka ng apat na lines)

1.HEL
2.OME
3.IDN
4.DME

Yung 1st and 2nd line may tig apat na letters na so bibilangin mo kung ilang letters nalang yung natira. May 12 pa diba? so ibig sabihin hahatiin nalang yung 12 na letters na yun para dun sa 1st, 2nd and 3rd line

1.H | E | L | P | M | E | S
2.O | M | E |O | N | E | K
3. I | D | N | A | P | P | E
4.D | M | E
