1 year agoI don’t see how filtering by karma combats bots whose whole job is to farm karma. Wouldn’t that just filter new bots until one of their posts takes off in some other community that does allow new accounts to post?
One of the main differences between hashing and encrypting is that encryption is réversible by some means, while hashing isn’t. The irreversibility is what makes it so ideal for storing a password in a way that definitely can’t be used to get the original password back, even if someone steals the whole database with the passwords in it.
Those companies that ask for specific characters might be encrypting the passwords, but they definitely aren’t hashing them.
