Read password without echoing it back on terminal over network

[winged sleet]

hey all,

I am an absolute beginner trying to learn Rust by writing a TUI. The goal of my program is to listen on a port on the network and serve some secret content whenever a user connects and authenticates very similar to SSH/telnet. Using termion I am able to get username and password (without echoing it back to the terminal) just fine but how can I replicate the same behavior for password over the network?

termion has a https://docs.rs/termion/latest/termion/input/trait.TermRead.html#method.read_passwd method but I can only find an example that works with stdin. How can I use it over the network?

Is this even the right direction to look?

P.S. this is purely a learning project and not a production one. A good excuse to learn Rust.

Thanks in advance

pls tell me you're hashing and salting the password on the client and sending the hash over the network

ah alright, just making sure

If you look at the implementation of the read_passwd function, all it does is setting the terminal to raw mode before reading a line and disabling raw mode again afterwards
