Question

if in a certain code language MEDICATE >written as GVCEKFGO. then how will VALIDATE be written in the same code language?

Answer 1

Let’s give this a good ol’ fashioned try.

First attempt: Plain caesar cipher (a transposed alphabet, easiest substitution cipher) => No good, repeat letters don’t match (E -> V and O)

Then I noticed a pattern, if the ciphertext is mirrored, the letters match up for a substitution cipher, so let’s find out what offsets we have:

mirror("GVCEKFGO") => "OGFKECVG"

 

pl ci of

----------

M O +2

E G +2

D F +2

I K +2

C E +2

A C +2

T V +2

E G +2

So it was a caesar cipher after all, with the translation offset of 2, and then the product is mirrored to produce the final ciphertext.

So, encoding “VALIDATE” with the same function would be:

VALIDATE => XCNKFCVG => GVCFKNCX
