      Brian Hayes Retweeted Anna "Code Archaeologist" Filina

      Hmm. Is there a secure hash function that measures edit distance between two passwords without knowledge of the plaintext?https://twitter.com/afilina/status/785864310648082433 …

      Brian Hayes added,

      Anna "Code Archaeologist" Filina @afilina
      Yahoo: "Your password is too similar to the one you've used previously." You wouldn't know unless you store it in an insecure way, again.

      I expect this can be done with homomorphic encryption. V. much doubt that's what Yahoo is doing.

          It can be done in the browser with JavaScript, but that's also not how Yahoo's doing it. (If they *are* doing it.)
