# It all starts with a message

I saw this in one of the forums I frequent (user said it was from reddit).

I tried to solve it, and the only thing I got was that there is one English letter followed by one hexadecimal number (this might not be correct). So help me find the answer to this code.

Found this answer somewhere in the comments on some other site:

The message says "maybe its (it's) time to wake up".

It uses a simple caesar shift:
a1-a6 = A-F,
b1-b6 = G-L,
c1-c6 = M-R,
d1-d6 = S-X,
e1-e6 = Y-D (alphabet wraps around),
f1-f6 = E-J,
g1-g6 = K-P,
h1-h6 = Q-V, etc.

Capital letters are equal to a '0' of that letter group which correspond to the last number of the previous letter group:

E = e0 = d6 = X
F = f0 = e6 = D

Then each word has a different "shift-number" (how many letters the letters get "shifted" over):
With a "shift-number" of +4:

a1-a6 = W-B,
b1-b6 = C-H,
c1-c6 = I-N,
d1-d6 = O-T,
e1-e6 = U-Z,
f1-f6 = A-F, etc.

E = e0 = d6 = T
F = f0 = e6 = Z

Just use this principle, changing the "shift-numbers" for each word, to decrypt it. The first word has a "shift-number" of '+0', then '+4', then '+4', then '+14', then '+6', then '+14'.
