A hash of a public identifier like an email is personally identifiable data.
- pfortuny 8mo agoYou can always encrypt with a public key instead of hashing.
- jounker 8mo agoIsn’t the entire point of a cryptographically secure hash that you can’t derive the original information?
- charcircuit 8mo agoYou can't derive the original better than guessing. With public identifiers you can just take a list of them and guess with those. If someone asks for your email they can hash it themselves and compare it against whatever databases.
