Ask HN: Secure ways to transmit a WiFi password via Bluetooth

For this scenario, imagine having an Android app that needs to send a WiFi password via Bluetooth.

Any secure way to do this without someone being able to intercept it?

Diffie-hellman key exchange and then encrypting it with the generated key?

Couldn't someone just capture the key too ?

Amazon definitely does this with Kindle tablets, I'd love to see a code snippet.

They can capture tge communication but there is no math that can be used to decrypt it. The only way is bruteforcing it. for the rsa diffie hellman you need a few kilobyte for the keys and communication, but its easy to implement.

I'm sold, do you have an example to share ?

Just go to wikipedia or search it.
