There is a mobile app (called “Rattlegram”) that converts a string of text to a wave of audio (played though your phone’s speaker) and then someine on the receiving end could also use this app to decode.
You can use Secure Space Encryptor (SEE) (known as Paranoia Text Encryption on iOS) which is a Open Source encryption app that can turn text into a string of ciphertext using symmetric encryption. Paste the ciphertext on Rattlegram and send it over amateur radio.
Then just decode and decrypt on the other end.
Warning: Encryption over amateur radio is illegal, this is for entertainment purposes only.
(I mean you could also just send the ciphertext over SMS 🤷♂️, but ham radio is cooler 😎)

That’s pretty cool, nice tool for the communication toolbox
