Question

Heather has encrypted her name to become Jgcvjgt. Her associate is given the encrypted name Tqdgtv – what is her associate’s real name?

Answer 1

R..ert , so my guess is Robert.
Substitutions cipher.
H=J
e=g
a=c
t=v
h=j
e=g
r=t

Answer 2

Heather has been encrypted as Jgcvjgt. This would be deciphered as:

J = H, G = E, C = A, V = T, T = R

Therefore we can deduce that TQDGTV, from the letters we have already deciphered, will be ROBERT. We can make an educated guess what Q and D are two reasons, one; that the name looks like it is Robert as we know this to be a real name and two; if C = A it would make sense that D = B, and if T = R then Q = O.

c d e f g (cipher) = a b c d e

q r s t u v (cipher) = o p q r s t
