Cryptography Game
« on: April 30, 2016, 07:37:32 PM »
Anyone want to play at decrypting easy"ish" messages using pretty standard ciphers?

I'll start:

R5G657R 0K =[E0K R0UI7 E65 7I5 RK5EP05R7

Ask any relevant questions, I want this to be fun.

If you're starting with 64 characters right off the bat, you're already out of my "easy" territory.

I'm intrigued, but if it's anything beyond simple substitution, I'm lost too.

Hints:

1. It is a simple substitution cipher. The characters correspond to the actual words.

2. Try this:  http://www.characterfrequencyanalyzer.com/english/

Give me a few hours to submit a new one, and if I haven't posted by this evening someone else can make a new one.

Trying to find quotes without "a" or "I" in them is a pain in the ass.

Should be even easier than drw's due to the length.  Punctuation has been omitted (for the most part).

Besides substitution or substitution + shift, the only other ciphers I know how to make are Vigenere.  And I doubt I have the time or motivation to solve anything besides substitution at this point, but I can certainly contribute more.

This a famous quote from a famous author. It uses a "classic" cipher with a "Latin" flavor.

Also a resource I've found to be helpful and a lot of fun is by a fellow skeptic Simon Singh

I was hoping "The Latinist" would get a Caesar Shift cipher.

From The Black Chamber:

According to Suetonius, Caesar simply replaced each letter in a message with the letter that is three places further down the alphabet

I used an 18 letter shift for this one.

Yeah, I tried three first.  I'm a little busy for the next couple of hours; if someone else wants to propose one in the meantime, please feel free.

Use the birthday of the author of the above quote to solve this code.

Should we make this a collaborative effort, Latinist?  My first attempt at this one failed.
