So I haven't posted very many questions and I'm not yet very good at figuring out how many clues to include. In addition, I realize that the key behind the third cryptogram is not at all obvious so it might need some more help but I don't want to give the game away. I'll give it until Monday and then I'll post some more obvious hints.
Can you decode each of the cryptograms below and then answer the challenge they pose?
There may be solutions to the puzzle-within-the-puzzle that I haven't thought of yet. Any such solutions will receive an upvote but will not be accepted as the answer unless the answer I was thinking of is never found (doubtful) in which case the most upvoted answer will be accepted.
Clarification on the hidden challenge:
End of the first day hint:
As @JasonPatterson hinted at on the answer by @GentlePurpleRain there are clues in the third cryptogram. In fact, the first three sentences of the cryptogram each contain a clue. Three sentences, three clues, three cryptograms. That nae be a coincidence, laddy.
End of the second day hint:
For the first cryptogram: Don't think of the key as starting with "A encodes to S". It starts with "Q encodes to K". Now, why does it start with "Q" and why does that become "K"?
For the second cryptogram: The words from the first clue with the Z and J are there for a reason. Those are rare letters. Where have you seen those words together before? (@GentlePurpleRain has already solved this one)
For the third cryptogram: @JasonPatterson already found the key word in the encoded clue. The method of applying it may be fremd for individuals vacant of experience. How can you go from the resulting mess back to a letter?
End of the third day hint: (not optimized because kids just started screaming)
1) Your clues are: "IF YOU GET STUCK DONT GET TOO KEYED UP". It starts with "Q encodes to K". Try looking down. Recall that Q is the 17th letter of the alphabet. But what if two letters encode to the same result? That's not allowed.
3) Your clues are: "JUST KEEP GOING AND HASH IT OUT". The method of applying it may be fremd for individuals vacant of experience. After you hash it out, you have to convert it back to a number. Try to use as little of the mess as possible to get a unique encoding. But what if two letters encode to the same result? That's not allowed.
Beginning of the second week hint:
1) If you're viewing this on the desktop site - I.E. not the mobile site - and you look down, what do you see with keys on it? Since Q is the 17th letter of the alphabet, what comes 17 keys after Q? What comes 23 keys after W?
3) After you hash it out, you need to get back to a letter. How can you take the first tiny bit of the hex mess and modify it to get a decimal equivalent to a letter? How little a bit must you take to get a unique result?
