-A transposition cipher.
-The key to breaking it is following its route when reading the ciphertext.

Encryption:
Plaintext: They say oh my god I see the way you shine.

•Isusulat natin ang plaintext in grids. Kung ilang columns, that would be up to you. Kung may empty spaces man, fill it up with letter x.

T H E Y S A
Y O H M Y G
O D I S E E
T H E W A Y
Y O U S H I
N E X X X X

•Sunod ay mag-iisip tayo ng route na susundan. Itong route na sinasabi natin ay pattern na maari sundan sa grid. Example, the route will be inwards spiral starting from T downwards:
Ciphertext: TYOTY NEXXX XIYEG ASYEH ODHOU SHSAE YMHIE W

•Try natin ibang route. Subukan natin horizontal route mula sa top right.
CT: ASYEH TYOHM YGEES IDOTH EWAYI HSUOY NEXXX X

•Isa pa. Pa-zigzag naman from top left.
CT: THYOO EYHDT YHIMS AYSEO NEUWE GEASX XHYIX X
