Code #1

Observations

Get the passcode format, what could the keyword convert too if you had done it before

Spoiler

Reverse the code

For the keywors, convert 4 to roman numeral IV and reverse to get VI

rpf49vi862od

Passcode format is there, keyword is not that easy to figure out

Spoiler

Atbash letters and numbers

For the keyword, light has been thought to be either a wave or a particle

qra97particle465cv

Those are not letters, we are just not used to see this range

Spoiler

Convert letters to numbers using a=0

11 4 10 3 10 3 0 5 10 5 0 11 11 12 10 11 10 0 5 3 0 5 20 5 21 1 2 1 12

Hard to see but this is a good Ascii range. Make groups of 3

114 103 103 051 050 111 112 101 110 053 052 052 112 112

Convert decimal to Ascii
