Encrypted Message

Briefing:

We have an undercover agent in one of the Slootmaekers bike shops, posing as a bike mechanic. We need to send him an urgent message but the only phone he has is one the gang gave him and may be monitoring. We have a specific Substitution Cipher we can use - quickly encode the message and send it.

Tip: Correctly encrypt the message and send it to get the flag.

Hint:

Simply replace whatever each letter in the message is with whatever letter the key tells you to change. For example, if the key shows A = S, change all A’s in the messages to S’s.

How to Solve:

  1. Convert GANG MAY KNOW YOUR IDENTITY ABORT ABORT MEET AT SAFE HOUSE B using the cypher:
    A = F   B = G   C = H   D = I   E = J   F = K   G = L   H = M   I = N   J = O   K = P   L = Q   M = R   N = S   O = T   P = U   Q = V   R = W   S = X   T = Y   U = Z   V = A   W = B   X = C   Y = D   Z = E
