NostrMail
⚠️ Pre-release Notice: This is a pre-release build and may have bugs. We recommend generating a new keypair rather than using an existing one.
NostrMail encrypts email content using a symmetric key derived from a combination of the sender's private key and the receiver's public key. Both sender and receiver derive a shared secret known only to them, which is used to protect their communications.
This application can use any email server for delivery while leveraging Nostr's decentralized social key registry for key discovery and management.
Features:
- SMTP Email Sending and IMAP Email Fetching
- End-to-end encryption using NIP-44 (default) and NIP-04
- Nostr direct messages and contact management
- Profile management with Nostr social key registry
- Cross-platform support (Windows, macOS, Linux, Android)
