A Python-based encrypted voicemail system was built using Twilio's Programmable Voice API, Flask web framework, and the cryptography library. The application uses a public-private key pair to encrypt voicemails left by callers on a Twilio phone number. A dashboard is provided to view, decrypt, and listen to these voicemails. The application also includes functionality for deleting voicemails stored in Twilio's servers and locally on the system.
