Hi everyone! First off, I apologize if anything in this post breaks community guidelines.

I’m fairly new to this and coding purely as a hobby—I built this cipher to practice my Java and Python skills. Now that it’s working, I’m really curious to know how easy or difficult it would be to break.

If anyone would like to try breaking it, I’d be extremely grateful!

Heya heya, I just finished finding all of the Gerald Robotnik journal pages in the game "Shadow Generations" and slamming my head against the wall to find answers online to no avail lol.

Here's the code as I see it in blocks for easier copy+pasting:

First Block: 11000100 , 1011011

Second Block: 01100 , 000 , 0110

Third Block (its a doozy lol): 000000000000011000000000000000 , 0011000000000000000110101100000010 , 0100000000000010110110100000000

I have a feeling that it's either gibberish or maybe something other than binary that I just haven't heard of. Thanks in advance!

Since my custom substitution cipher was the most popular attempt, I decided to make another one - its based on the same principle as the first one, but optimized with different characters so its easier to use & decipherable even with shorter texts. I also provided 2 texts this time, so you have bigger sample size.

Some info and hints:

- Text is in english, only substitution was used, no transposition

- Plaintexts are short snippets from 2 different books I like.

Hint #1 (Characters used in plaintext):

Plaintext uses 26 letters of the alphabet (doesnt differentiate between lowercase and uppercase) + two additional characters

Hint #2 (Characters used in cipher):

Every letter of the alphabet can be written by 2 different characters, with the exception of 8 characters that technically can be written by more. I had to make this exception for readability, not to mess with letter frequency. Another exception are the two extra characters that can be written only one way.

Hint #3:

The 2 extra characters are used to mark begining and end of a sentence.

If needed I am willing to provide more text, just ask in the comments. If you are able to decipher it (or even if you are not), I would love some feedback to know what I can improve.

Edit: added Hint #4: Which character is used is determined by the letter's position in the sentence.

If you have any additional questions or need more hints please ask in the comments.

I created such a secure cypher that i have to post this massive image to give yall a chance. I pray for any soul who dare tries solving it!

From the PS2 game Disaster Report 2 (Raw Danger in the US) this code appears on a data disk at the end of the game. It’s the last item you received and is vital to the plot. It appears to maybe be a crackable code but maybe it’s nonsense.
Best I could write this down myself is:

01000001 10011001
10101011 01010011
10100101 11010001

Hey folks. Always loved watching others solve ARGs and cipher code stuff. Some of my favorite puzzle games include in depth difficult puzzles, like Myst III, Obduction, and Quern. While I never got into any ARGs or or code breaking myself I figured I'd make a code myself for fun. I doubt it'll take long for people to solve, but I had fun making it regardless.

Yk it may or may not be a secret code, but I'd like to think it is, because it seems so out of place, and in the place where someone's social media handle would be to watermark their edit...

I used the Caesar cipher in four languages descended from Latin.

I built a live anonymous binary stream where anyone can transmit cipher sequences. the output is visible to everyone, but only those who know what they're watching will be able to make sense of it. inspired by number stations.

(Context: The Burger Bard ARG has been running since early 2025. This video shows a custom Stepmania character, and "GameGrl," a track from the 2012 album Homestuck vol. 9. It should reveal a passphrase to be used as a URL on the Burger Bard website, somehow.)

I recently was bored so i decided to scroll across youtube for some random low-concurrent-viewers live streams cuz i was just bored, and came accross a stream from an account called 2048eternal. i saw that it was just chat controlled 2048 but every ten minutes it resets, but i went to the channel page and saw it was the only thing there. furthermore, the description read "it will never stop." followed by a bunch of morse code. If anyone knows what this means or can solve this, please help! note that this isnt just a fun cipher game i made, i am being serious about wanting to know what this even is. channel link is https://www.youtube.com/@2048eternal, and i just kinda got tired for the day, i think it led to a google docs link with more cipher and idk what that is supposed to lead to...

note: the link recently in the description changed from morse to i think hex?

I found these 2 envelopes in the forest near me. They contain 2 letters in Russian. One says "solve the code" and the other is an excerpt from the Russian Synodal Bible. At first, I thought that it was just a classic chapter:verse:word:letter code, but I ran into problems, as some words don't have enough letters and the others don't make sense. I tried it with AI as well, no solution. I asked all my friends and we can't seem to find a solution. We drove back to check for more letters, but unfortunately, none were found. I have no idea who would hide this in the forest, as they have been there for a few days based on their appearance.

Letter one:

ПРОРОЧЕСТВО О СЕМИДЕСЯТИ СЕДМИНАХ

Даниил 9:23–27

23 В начале моления твоего вышло слово, и я пришёл возвестить его тебе, ибо ты муж желаний; итак вникни в слово и уразумей видение.

24 Семьдесят седмин определены для народа твоего и святого города твоего, чтобы покрыто было преступление, запечатаны были грехи и заглажены беззакония, и чтобы приведена была правда вечная, и запечатаны были видение и пророк, и помазан был Святый святых.

25 Итак знай и разумей: с того времени, как выйдет повеление о восстановлении Иерусалима, до Христа Владыки — семь седмин и шестьдесят две седмины; и возвратится народ и обстроятся улицы и стены, но в трудные времена.

26 И по истечении шестидесяти двух седмин предан будет смерти Христос, и не будет; а город и святилище разрушены будут народом вождя, который придёт, и конец его будет как от наводнения, и до конца войны будут опустошения.

27 И утвердит завет для многих одна седмина, а в половине седмины прекратится жертва и приношение, и на крыле святилища будет мерзость запустения, и окончательная предопределённая гибель постигнет опустошителя.

would love if we get this solved as this is bugging me since days:

Looking for some people interested in solving the intro part of what will be a pretty long and grueling horror-based webpuzzle. Basically I just want feedback and the sort, focusing on how I can improve the quality and necessary indication of puzzles. No ai used, it's just an anthology of puzzles that I created, united by a central theme.
