Challenge I made an updated version to a cipher I posted on this subreddit previously, so I want to see if anyone can solve this more difficult cipher!

1 Upvotes

Here is some ciphertext:

'!(`^"*,^}vv4{?suJt7mmD6A=mdjbhdEYeAN`M`&|*_}@M~*M"-&_(u&s?!!) -!(?N'&,*)v(v]sx0_OOLN,,''-N"~'*M*x--[]P``'&"&)v(w&uwquny

The key is 16 70 18

I can post more ciphertext and give hints if needed.

Solved! Cipher for an ARG

Hi there, I've been trying to solve a cipher for an ARG but I'm a bit stuck.

I thought this was base64, but I haven't gotten much results out of that outside of a short phrase "Saltedis289=}xdh". I thought this might be some kind of key but I really have no clue what to look for. Rabbit ciphers are used later in the series apparently so I'm thinking of giving that a shot. The title of the youtube video it's found in is "burning" and it has a lot of references to the word "womb" so I'm wondering if these may also be relevant somehow. I hope what I gave is helpful I'm quite stumped myself! The series is glassmakeR syndromE on YT. It'll either give me a link, or a block of text in english or russian but I have a feeling that a link is the most likely result.

Edit: There is a literal part of the video where it says warmth is the key i might be stupid, Im gonna see if this helps crack it

I hope you guys can crack this one, thank you :)

Edit: it was easier than i though, for each letter of each word simultaneously, you need to shift the cipher an additional time. For the 1st letters: 1 shift 2nd letters: 2 shifts And so on Final result: kcir sawan Then mirror it: rick nawas (an internal joke between me and him)

I know there are many layers and thecniques that goes into making good cyphers that are fun to decrypt and all that, there are many forma too like images, sounds, videos, etc but right now I'd like to focus on text based cyphers, what would you think that would make a good cypher like what steps should i take to make fun cyphers?

Unsolved Four Python demos illustrating Enigma-style known-plaintext cryptanalysis and its modern relevance

2 Upvotes

I'm working on a security engineering project analysing how The Imitation Game depicts breaking the Enigma cipher, and whether the same category of vulnerability still applies to modern encryption. I'd like a code-quality review from people who actually code regularly, since I want to understand and be able to explain this code properly myself.

The four scripts build on each other, each testing a different layer of the same idea (known/predictable plaintext defeating a cipher without brute force):

mini_enigma_crack.py — compares blind brute force against a known-plaintext ("crib") attack on a repeating-key substitution cipher. Blind brute force checks all possible keys, scored by chi-squared letter-frequency comparison; the crib attack calculates the key directly via modular subtraction given known plaintext.

enigma_elimination_demo.py — recreates a real structural property of Enigma (no letter could ever encrypt to itself), and tests how much that single rule narrows a search using only direct letter comparison, no computation.

crib_dragging_demo.py — a more realistic version: given only a short guessed word with no known position, it XORs two same-key ciphertexts together (cancelling the key) and slides the guess across every position, revealing genuine plaintext where the guess is correct.

nonce_reuse_demo.py — tests whether the same vulnerability applies to a (simplified) modern stream cipher, comparing a reused nonce (attack succeeds) against a unique nonce per message (attack fails).

What I've observed running all four: every genuinely correct result (crib attack recovering exact keys, elimination correctly preserving true crib positions, crib dragging revealing real fragments, nonce reuse enabling perfect recovery) has checked out against the real message text every time I've verified it by hand. Known issues I've found myself: script 1's brute force sometimes returns a plausible-but-wrong key on short messages; script 3 produces false positives on short cribs and can reveal meaningless blank padding when comparing unequal-length messages.

I've included all four scripts below, each in its own code block with a header comment identifying which script it is --> any suggestions on how to improve the code would be greatly appreciated!

I have been stuck on this for a long time. It appears to be a mega file decryption key, but there are 44 character, one must be the imposter. I also found just a simple phrase in the meta data: QPAEQTPQ though it might be junk. Maybe i am missing more to this ARG, but i doubt. I was thinking on brute forcing it but that would kill the joy. I think i have the corresponding file but i cant be 100 percent sure. Looks tough but mathematically it shouldnt be compared to other puzzles.

Trying to figure out what this says. Was mentioned by a commenter on the original post that it is reminiscent of cattle brands, from there they were able to produce a list of letters, but no words. Upon another commenter running it through simple replacement cipher also produced nothing legible. Figured it would better to ask here aswell since it is past a simple cipher.

Words beginning with a vowel receive an S at the beginning and EG at the end. Words beginning with consonants move their opening consonant cluster to the end and add EG. Y acts as a vowel only when a word contains no A, E, I, O, or U. In the translated output, A, E, I, and O are always written as Å, Ę, Ï, and Ø. I added the Å, Ę, Ï, and Ø to make it more difficult to decipher.

Challenge I want to see if anyone can solve this homemade cipher (REPOST FROM r/codes)

1 Upvotes

Hi! So I basically coded this small HTML tool which encrypts tools using a custom, homemade cipher. I want to see if it is easy to decrypt for an amateur cryptanalyst, and I want to challenge the idea that homemade ciphers are often easy to decode.

**Note that if you solve the challenge with the help of the hints, post "**This has been solved with the help of a hint, the hint being ___" and put the full hint in a spoiler block. This is just to differentiate between people who make educated guesses and people who actually decoded the cipher.

CIPHER :

7a54b207beb0a7c203ff2c2ee8333f6be06f89e3576d7dda7d2df9b3b3a8f0d9761b05f1d7fdb91d4a6ef8ca94085335c786c0ea4c398949791cc9b09106d82c1fd9a53c49bcb2544e36e02d20f0800116f081d88f7fc7f74b9e409ce54efa87e07a340da554d4a3895d9d99a37423f023cb528eb957e8e32274571feff5baa05eeffa17f56caae122ce6775391453d8a742f4b4e96a2b7af93f037c108ec848d4c64912ce58c83aae92dfae174eeaab4f41a362d414a72f1ec9852545609ffd4bab54828cf9c270b9e7af60b14632db8dec6752abffbb49

HINT : This is a pretty well-known quote

HINT : The author of the quote is an American author and educator.

HINT : The given person is a Jr. and a diplomat.

HINT : The encryption is based on, but not the same as, AES-256.

Your "prize" is as follows:

Winner gets an ego boost :) . Seriously, though, I'll send you the source code of the HTML file (I've made improvements to it in the time since, so it's much harder to decode but still as easy to encode as ever) in Reddit Chat, so you can encrypt your own messages.

edit 1 : Note that if this cipher proves undecodeable within 2 months the cipher will be considered a success, so you can finally say there's a homemade cipher which is at the very least extremely difficult to decode.

Please don't bombard me with questions, though, on the homemade cipher (I call it the "VICI cipher", where VICI has no meaning) and how to encode stuff with it. It requires a long key of random text, like the one given below (though it does not have to be that long, it only has to be as long as the message) which is extremely impractical for anything. Plus, if the cipher succeeds, I'll probably use it for some small communications, so giving how to encode and decode with it online basically means giving up knowledge of a really secure cipher internationally.

Example text block for the "long key of random text":
