-Encryption-
-Mag-isip ng date and i-convert sa numbers. Example,November 7,2018. Then it will become 110718
-Mag-isip ng word na gusto mong i-encrypt. Example,the word "Detective Codes".
-Ilagay ang numbers (ito yung date na ni-convert sa numbers) sa ilalim ng plaintext(which is the Detective Codes) at ulit-ulitin hanggang sa maging same na ng length.
Like this:
D E T E C T I V E C O D E S
1 1 0 7 1 8 1 1 0 7 1 8 1 1Sa encryption,forward ang gagamiting shift. And naka-depende doon sa nakatapat niyang number kung ilang beses mo siyang i-mo-move. Example yung letter D. Since 1 ang katapat niya,then magmo-move forward ka lang ng isang beses. And so on...
D-E
E-F
T- T
E-L
C-D
T-B
I-J
V-W
E-E
C-J
O-P
D-L
E-F
S-TSo,our cipher text will become like this: EFTLDBJWEJPLFT
-Decryption-
Kailangan given ang date. Same process but backward naman ang gagamiting shift.
