I haven't done a challenge in a while so here we are! I have created a new one for you all to try. The prize? A Bletchley Boffins gang tag! I'll be giving away three of these so if you finish, please PM me before you post in the thread that you've solved it and only post the solution once I have given the go ahead in this thread. You all have until at the latest September 15th to complete this. Proof of work also needs to be shared. Some of you have rightfully complained that there needs to be a raw copy of this so here's it in Base64: code:

i still feel bad for that time i posted a fake cipher and somebody asked me for a hint months later because they were still trying to solve it. as penance, i will also be giving the three winners a Bletchley Boffins gang tag. that's right - two Bletchley Boffins gang tags. good luck, boffins-to-be.

worked it outquote:What the gently caress did you just loving say about me, you little bitch? I’ll have you know I graduated top of my class in the Navy Seals, and I’ve been involved in numerous secret raids on Al-Quaeda, and I have over 300 confirmed kills. I am trained in gorilla warfare and I’m the top sniper in the entire US armed forces. You are nothing to me but just another target. I will wipe you the gently caress out with precision the likes of which has never been seen before on this Earth, mark my loving words. You think you can get away with saying that poo poo to me over the Internet? Think again, fucker. As we speak I am contacting my secret network of spies across the USA and your IP is being traced right now so you better prepare for the storm, maggot. The storm that wipes out the pathetic little thing you call your life. You’re loving dead, kid. I can be anywhere, anytime, and I can kill you in over seven hundred ways, and that’s just with my bare hands. Not only am I extensively trained in unarmed combat, but I have access to the entire arsenal of the United States Marine Corps and I will use it to its full extent to wipe your miserable rear end off the face of the continent, you little poo poo. If only you could have known what unholy retribution your little “clever” comment was about to bring down upon you, maybe you would have held your loving tongue. But you couldn’t, you didn’t, and now you’re paying the price, you goddamn idiot. I will poo poo fury all over you and you will drown in it. You’re loving dead, kiddo.

ya thats how far i got last night before my mind blew out notice how the freqs descend from A->Z but rise from a->z except J (19) j (0) fucks with the ascending/descending "pattern" by being outliers if you add the freqs A+a, B+b, etc, they become pretty regular, idk if that hints at something (maybe the alphabet is A-Z0-9, and then the a-z is just for obfuscation??) the special chars all have very low freqs, too oops ignore this graph, its the wrong one without the small j Carthag Tuek fucked around with this message at 19:14 on Aug 18, 2016 |

the distribution doesn't seem to match anything that'd be a straight substitution cipher. Since newlines are preserved I'm trying to focus on the first line since it's pretty short but that might not be a good idea, I dunno how to approach these things.

the line at the top is definitely a header some of the rest looks base85 encoded

nah im thinking it decodes to plain ascii or utf8. as OSI mentioned, newlines & certain special chars are kept so like the plaintext is a headline + 4-5 paragraphs actually OSI when you say spaces have been kept, you mean that the plaintext has not been stripped of spaces before encrypting? i mean there arent a lot of spaces in the ciphertext Carthag Tuek fucked around with this message at 23:01 on Aug 18, 2016 |

spaces were not stripped before enciphering. just because a character is uncommon in the ciphertext doesn't mean that it isn't common at all
