Code #1

Observations

Looks like hex but out of range

Let ‘s start by making pairs to see what we are working with

8b 8e 99 87 8c 8f 8c 7b 8c 88 96 7b 8d 7b 78 96 8c 7e 7c

Everything starts with either 7, 8 or 9. Let’s try Hex Atbash using this index

0123456789abcdef
fedcba9876543210

74 71 66 78 73 70 73 84 73 77 69 84 72 84 87 69 73 81 83

Convert decimal to Ascii

JGBNIFITIMETHTWEIQS

jgb95time328qs

All letters, go through your usual cipher routine

Atbash gives

aqksininzeereisefojh

aqk69nzeer874jh

The reverse of nzeer are the shaper

aqk69shaper874jh

All letters, you’ll need A key to decode it
