0 sats \ 1 reply \ @02fa90fd41 OP 16 Jun 2023 \ parent \ on: I have been asked to ELI5 cryptographic hashes to kids (grade 8).. Is this ok? bitcoin
If you have any suggestions I would appreciate another analogy
You can fix your example by using
salt || MD5(grade || salt || secret)
as the code on the lockers.salt
is just a random value which makes sure that every hash will be different.secret
is a secret value which only teachers know. This prevents that students can just try every grade and compare hashes.With
||
I mean concatenation.This may be too complicated for 8 graders now though.
