When you visually compare two hashes, how many digits do you check?

The strings hashed below are "retr0id_18b1f814a8e2d9c4fb9c" and "retr0id_1253dea672ebfa240e94", if you want to check for yourself.

@retr0id uhm yeah.

The first and last couple, but I also put them under each other so I’d get a visual disturbing if there’s a mismatch in the middle, sometimes I even use uniq
