# The cipher puzzle

One day, I found this crumpled up note. It said:

The M3, beta 3 ring 3,1 position 3 ring 3,1 position 3 ring 3, 1 position 3 ring 3, UKW c thin, gpayi isnjx xkxxs bjuqb xfjhp tfmit ouuf


So, what is the youtube video?

The note must have been very crumpled indeed.

This is an

Enigma cipher

but it doesn't really work at all:

• The M3 doesn't use the beta ring, nor can it use thin UKWs. The M4 does.
• The complete set only has one of each ring, you cannot put the same ring into multiple slots at the same time.
• Youtube URLs are case sensitive, this cipher is not.
• Youtube URLs can contain numbers, this cipher can not represent them.

So I'm really not going to bother with trying to figure out the actual video, and here's just the decrypted message:

Took me a while, but I think I found it.

Could it be this one?

• I'd upvote this if you could explain the answer. Otherwise, it feels like you're rickrolling everyone. (And yes, this is a spoiler to warn everyone before they click on the link :P) – Joe-You-Know Aug 9 '18 at 20:52
• Yeah, that's the point. I just couldn't resist – Cubemaster Aug 9 '18 at 20:55
