Relatively simple atbash cipher to start the marathon:

This is (hopefully) my first year doing Codebusters, so I'm not really familiar with how to solve things. That being said, here's another atbash cipher to continue the marathon!

This is also technically my first year doing Codebustsers so I love learning more:
Solve this Caesar Cipher with a shift of 3:
"Uron rb fqjc qjyynwb fqnw hxd'an kdbh vjtrwp xcqna yujwb." -Sxqw Unwwxw

I have no idea if you're supposed to put the shift number, but it was really great practice for learning word frequencies. ("gb" could translate to "id," "up," or "to," but "to" made the most sense so I started from there.
To continue with the Caesar cipher, solve this quote by Maya Angelou that was encrypted using the Caesar cipher.

Re: Codebusters B/C
In competitions, I don't believe Caesar ciphers generally include the shift number, but it's been a hot minute since I've taken an official test. Nice job working that out though!aakoala wrote: ↑September 24th, 2021, 1:25 pm "Coming back to where you started is not the same as never leaving."

Another Caesar cipher: solve this quote by Oscar Wilde: "Wsqi geywi lettmriww aliviziv xlic ks; sxlivw aliriziv xlic ks."
Again, another great practice for learning word occurrences! I originally started with "ks" decrypting to "we," but the first word made no sense. Then, it tried "ks" decrypting to "go," which fell in place very nicely. I also really liked the "wherever whenever" because they are so close to being the same word.
Solve this quote by Dr. Seuss encrypting using the affine cipher, given that (a,b)=(11,5). The quote is grouped by 5s; please let me know if this is against the rules.

To the world you may just be one person, but to one person, you may be the world.
I don't think the groupings of 5 are against the rules, although it's uncommon for affine. Historically, many tests group Vignere's into 5s although it's not explicitly stated on the rulesheet, so I'm sure it's fine for affine's as well. I'm no expert though.
Solve this quote which is from a notorious letter published by Benjamen Franklin. It's encrypted by the Rail Fence cipher, using 4 rails for encryption
(Sorry about my humor in advance, also don't include the spaces when decoding)

Re: Codebusters B/C
Oh, this was fun. I've never done a Rail Fence before, so this was definitely a bit of a challenge, especially in figuring out where each row started and ended, but it was great. I love the quote!

That all well bred people therefore forcibly restrain the efforts of nature to discharge that wind.
