Comment on OP finds vulnerability where a forum sends you your password in plaintext over email and everyone misses the forest for the trees

  Reversible hashed password storage isn’t meaningfully better than clear text.

  • The key to reverse the hash is typically (necessarily) stored in the same infrastructure as the password. Bad actors with access to one have access to the combination.
  • Even if an attacker fails to exfiltrate the key to the reversible hash, it’s typically only a matter of days at the most before they can reverse engineer it, and produce plain text copies of every password they obtained the hash of.

  A reversible hash provides a paper thin layer of protection against accidental disclosure. A one way hash is widely considered the bare minimum for password storage.

  Anyone claiming a password has been protected, and then being able to produce the original password, is justly subject to ridicule in security communities.

    The one they were sending at registration was prior to hashing.

      That’s technically less terrible, then.

      Good for them.

  I wasn’t trying to claim what was happening here, simply that one (extremely) bad practice increases the chance of another.
