Remember: loose lips sink ships
Sending someone a message on the internet for their eyes only? Use public key encryption.
Create your public / private key pair using the free open-source app OpenKeyChain. Then publish your public key to your website, social media profile, email footer or public key server etc. (anywhere it is tied to your identity)
Not only can i send someone a message if i have their unique public key. I can also verify someone on the internet is who they say they are – and so foil imposters!
How? I send a random message to Sandra using Sandra’s public key. Then publically challenge Sandra to reveal the message i sent. Smart huh?
Download OpenPGPChain from the trusted f-droid app repository (support f-droid), and check out this short explainer video on Youtube (i can’t find a better video host)…
Before i forget: this is my public key. Feel free to send me an encrypted message.
NB: Repeat after me. I WILL NOT reveal or post my private key. EVER.
