At a guess, the key appears to be

where the characters marked with ? do not appear in the given text.

The key I used is rather simple: First letters all replaced by vowels in order, then consonants in inverse order. Plus, Voltaire is awesome.

[Stefunny]

Okay, Stefunny PMed me a solution to my cryptogram, but she hasn't posted a new one. I'm opening it up to anyone who wants to.

Sorry, I got your PM on my phone and then forgot
Plus I haven't had a chance to figure out a new one.

[Packbat]

No worries, Stefunny - that's why we have mods in MishMash, to keep things rolling.

Feel free to post it anyway, if you like - the quotation is a favorite of mine.

[theplague42]

Alright very nice, more activity. Sadly, I've been rather

lazy

absent-minded regarding this thread. I'll try to do more this month.

@Packbat
I think I'm going to change around the OP and rules some. Some of the multiple-step rules are pretty much useless. I'll just change it to one-step only.

[Packbat]

Agreed - given how poorly even a Playfair went down, I think restricting it to one-step ciphers is quite reasonable.

[theplague42]

Changed. Acceptable?

[Packbat]

Looks fine!

Hey, not all of us work for the NSA cryptanalysis department

[Packbat]

Lord Peter Wimsey and Harriet Vane solved one in

all right - admittedly, the plaintext was quite a lot longer.

Edit: Also, they were fictional.

Feel free to berate me for poor time-management skills.

[Otolia]

Just for the fun, I have decided to follow a quantum computer / quantum cryptography lesson, if I stumble across something doable by normal people (as in never studied physics) I will post it there. Though I think it will be hard for me to propose something.

The really interesting thing you're
dying to read right now is the thing
that you yourself haven't yet written.

I will have to look into posting one >.< I've always DEcyphered, not cyphered. Lol.

Google suggests Rumkin's page if you want a web interface for encypherment.

[Packbat]

Bump again. I'm opening this one up to the public once more, just to keep it moving.

[Packbat]

Once again:

[Stefunny]

I almost have it done, I just don't have time to finish before work. I will post a new one with it this evening.

[Packbat]

Looking forward to it!

[Packbat]

Actually, suggestion: should we have two parallel ciphers going - one easy Aristocrat like the simple substitutions we've been using, and one more sophisticated but still susceptible to human-powered attack? Might be a little confusing, unfortunately.

[Stefunny]

Well, I have not really ever done anything different than the type you have been posting, but I'm becoming fairly quick at them which means they are almost too easy. I wouldn't mind trying some harder ones, I just may need a little help. I'm willing to learn!
