A hidden message (Posted on 2014-01-06) Difficulty: 3 of 5
A message was sent to our Math teacher.
She immediately understood that this is a simple one-to-one substitution code, with some punctuation signs.
However it took her a significant time to get the message and to restore the keyword, or rather the "keyphrase".

Can you accomplish both tasks and code a meaningful answer, using the same code?

Some Thoughts re(3): 0919192 etc HINT -re keyword Comment 5 of 5 |
(In reply to re(2): 0919192 etc HINT -re keyword by Charlie)

Below the ABCE....XYZ I  wrote the key phrase JUSTFORKINGADY, followed by the unused letters written in reverse order: ZXW...ECB.

E.G.    02-25-12-21  O4  DECODES C-Z-M-V   E  (lower line)

I did not look for the source of possible error (mine or yours)
