r/Cipher

Edit: I don’t know how to undo the solved flair, but I changed the decrypt message a bit and another A$20 is up for challenge

About a month after I started learning to program, I decided to write my own encryption algorithm from scratch. I know it’s almost certainly not cryptographically secure, but I’m curious how difficult it actually is to break.

I put together a website where you can try the encryption out:
https://encryption-thing-v1.vercel.app/

Challenge: Decrypt the challenge ciphertext on the site.

The decrypted message contains instructions on how to contact me and claim the prize.

Prize: The first person to successfully decrypt the challenge message and contact me as instructed will receive A$20 via PayPal.

I’m not claiming this is secure or comparable to modern encryption like AES. This was simply a project I built when I was about one month into learning programming, and I’m interested to see how experienced programmers and cryptography enthusiasts approach it.

I’d also really appreciate it if the winner could explain how they broke it so I can learn from it.
Good luck!

Hello, friends. Here, I present to you a secret class character sheet from the TTRPG, You Will DIe in this Place. This cipher has given me no end of trouble and I really would like to see it solved one day. A couple things are certain based on comparing this to other character sheets in the game.

• “Zgacig Xuva” is "Player Name"
• "Kbatonfop Ruyo” is “Character Name”
• “Kuproepc Wehe” is “Campaign Name”
• “Alsoogacja” is “Appearance”
• “Zovwzook” is “Portrait”
• “LOA CEIL IW YBAV NLAGE” is “YOU DIED IN THIS PLACE” and “LOA ZEVY QIA IZ WDEQ WDATUY” is “YOU WILL DIE IN THIS PLACE”
• “Dqvovsfv” is “Strength”
• “Ravhoqerh” is “Dexterity”
• “Axpugnohjy” is “Intellect”
• “Hidegawy” is “Vitality”
• “Trifohay” is “Stamlina”
• “Ojlugeuj” is “Injuries”
• The very difficult to read text under “LOA ZEVY QIA IZ WDEQ WDATUY” says “Character Sheet”

This isn't just nonsense. The author wanted to make it very tricky to figure out how this class works and hid it behind a cipher, but it very likely uses a system similar to Resident Evil inventory management. Please let me know if you have any ideas.

Okay so, about a day ago, a game called Animal Company uploaded a video that had morse code of this phrase,

"L7V4B5J8"

I have tried everything I could have personally tried to decipher it, but to no avail.

So now I come here to ask for help with decoding this phase because I am very curious about what it means.

(The video has since been replaced with an easier cipher as apparently this one was too hard, so hence why I'm asking for help 😅)

A few days ago, I received a message from an unknown account on Discord. It had no name or information, just a string of characters.

I thought it was spam or some kind of joke, but the account disappeared shortly after. I tried decoding it, and this is what I found.

I don't know if it means anything or if anyone else has seen something similar.

I call it a TX7 cipher

a = n@^

A = N26

b = f#$

B = F34

c = g&*

C = G78

d = r%!

D = R51

e = a()

E = A90

f = z#*

F = Z38

g = d)!

G = D91

h = g^!

H = G61

i = j%#

I = J53

j = i#%

J = I35

k = w*(

K = W89

l = z)!

L = Z01

m = m))

M = M00

n = n!!

N = N11

o = q#!

O = Q31

p = x%)

P = X50

q = p!(

Q = P19

r = v@)

R = V20

s = l#$

S = L34

t = r&^

T = R76

u = f$%

U = F45

v = d^^

V = D66

w = p@!

W = P21

x = s)@

X = S02

y = u#$

Y = U34

z = a)(

Z = A09

The captials don't really matter but I thought it would be fun, also it seems familiar to me but if a cipher like this already exists i am just gonna keep using mine because it took long

Hello all I am a college student who is very intrested in ciphers and I have a good understanding in math and computers. I have a good understanding of many base level ciphers and crypytography such as caeser cipher, base64, binary, simple substitution methods, and stegonography. I have had an intrest in these things for a long time as I am a fan of many ARGs and other mysteries that use ciphers. I have had thoughts of creating something similar to these works but I am not fully knowledgable on more difficult ciphers yet and I am hoping there are some good recomendations here of ciphers or how to find them. Some ideas I have had in the search are:

- Looking in my schools library and archive for old cipher books. (I go to one of the oldest colleges in the nation)

- Trying to make my own cipher. ( I am unsure where to start with this but I am sure I can do it with time)

- Finding niche ciphers through reddit or other places online.

If you all could please give any recomendations or advice that would be helpful. Please ask any clarifying questions if needed. Thank you!

I was cleaning out some old stuff and I found this journal, this is the only entry in the journal and the other pages seemed to be ripped out.
it looks like substitution but more like an abjad but with all the vowel markers on it.
can someone help me decode this? Thanks
