"What the Hex" was a crypto challenge worth 15 points.
Decode using hex and see what you get...
6236343a20615735305a584a755a58526659323975646d567963326c76626c3930623239736331397962324e72
Only needed my terminal for this.
First I decoded the hex encoded string.
$ echo "6236343a20615735305a584a755a58526659323975646d567963326c76626c3930623239736331397962324e72" | xxd -r -p
b64: aW50ZXJuZXRfY29udmVyc2lvbl90b29sc19yb2Nr
Then I decoded the base64 encoded string
$ echo aW50ZXJuZXRfY29udmVyc2lvbl90b29sc19yb2Nr | base64 -d
