Just a note. I used the digest node from node-red-contrib-crypto-js to ofuscate the PIN number.
for:
Basically I precalculated the digest (selecting your digest type) . Then converting the form msg from passcode to payload, pass to the digest and return the payload to passcode. Finally change the code to compare the digested strings.
It works fine and you don't expose your pin, not even on messages.
