Passwords sent as plaintext?
Passwords sent as plaintext?
I tried logging in on browser and I had inspected the request. My password was sent in plaintext. Is this a infosec.pub issue or a Lemmy one?

Passwords are always sent to the server, then it is hashed to check it against the value in the database. It's also possible to view your password by inspecting login requests from other websites. TLS is used to secure it while in transit.
Hashing is done as an extra measure of security in case the database is compromised. This measure of security would have been completely void if the server would accept password hash directly. You could log in as any user by using his compromised hash.

Why not hash it server side too? I'm asking because I'm curious

That doesn't make any sense. If you hash it once on client and once on server, that means that your password, as far as the server knows, is the client-hashed password. Nothing has changed in terms of security. In fact, you could implement this yourself by hashing your password when creating it and when supplying it.

Yeah now that you put it this way I realised my mistake. Thanks

That's actually a good thought though. It would prevent (clear text) password leaks from shitty / malicious websites. Having a standard for browsers to salt and hash password would have prevented a lot password leaks. On the other hand it could never be updated and we would most likely be stuck on md4 or something similarly broken.

Because it provides no advantage. TLS is used to secure any data sent to a server. If you don't trust the server with your password, then you should use a unique password for this website. In fact, you should always use a unique password.

Okay. I am pretty new to this stuff so I'll go and check out SSL/TLS. Thanks :)
