Cipher: ༽遄䮣丁༽䮣靆뫞遄脇䮣༽䮣丁뫞靆脇カU䮣カ༽遄丁脇遄丁遄
Description/hint: A text that's encrypted using Python 3.
Here are the first 4 lines, with the fourth line cut off.
should be replaced with a null char.
def encrypt(plaintext,keytext):
text = plaintext
for key in :
step1 = “”.join([chr(((ord(character) * k

Cipher: Lynnq
Description/hint: Squares.

Manually encoded (which is why it's so short), so expect some errors.

If you solve this, please post the method by which you solved it due the high frequency of the word I encoded.

I guess the topic should be revived at some point, right?

Description/hint: Squares.

Plaintext: [yaay you solved it]
Solution: [convert each character to decimal, take the square root, convert back to ascii]
I tried this method with bignate469's cipher but it doesn't work, I'm guessing you did too?

Plaintext: [Hello]
Solution: [For each letter, get it's index in the English alphabet (A=1, Z=26), find the numbers whose squares are that index modulo 26, then get the letters at that index in the alphabet.]
JS code: [[..."Lynnq"].map(x=>parseInt(x,36)-9).map(x=>{var arr=[]; for(let i=0; i<26; i++) {if(i*i%26==x%26)arr.push(i);} return arr.map(x=>(x+9).toString(36));})]

Description: It's a graphical encoding, I encrypted it by hand on a square grid
Hint: 3x5
(if the box drawing characters don't line up in the cipher, try using a different monospace font)
