I know this cipher teks but dont know what the type of cipher, and for know this cipher type i use tools identifier and this result of indentifier
↑↓ ↑↓ ASCII Shift Cipher ▪ Whitespace Language ▪ Substitution Cipher ▪ JSFuck Language [][(![]+[]) ▪ Ook! ▫ Babylonian Numerals ▫ Base91 Encoding ▫ Gold Bug Cipher 3‡0†2?3 ▫ Homophonic Cipher ▫ ROT-47 Cipher ▫ Blub! ▫ Tom Tom Code ///\\/ ▫ ReverseFuck ▫ ASCII85 Encoding ▫ LSPK90 Clockwise ▫ Morse Code ▫ HTML Escape ▫ Tap Code Cipher ▫ Keyboard Change Cipher ▫ Decabit Code ▫ HTML Colors ▫ UUencode ▫ Spiral Cipher
when see the result i fix 100% this keyboard change cipher because the logic can use number on cipher, and this result after decode
60;170;114;64;165;147;150;173;113;63;171;142;60;141;162;144;137;61;163;137;110;63;114;120;106;125;61;61;175
from here u can see 175 before } ithink this octal and me make this python script for solved this chall
listoffile = [60,170,114,64,165,147,150,173,113,63,171,142,60,141,162,144,137,61,163,137,110,63,114,120,106,125,61,61,175] newlist = [] for x in listoffile: newlist.append(chr(int(str(x), 8))) print(''.join(newlist))
and run the python script
