Sudo Encrypt vs BurnPony Self

- Generate RSA keypairs locally - Import others' public keys and encrypt messages to send to others - Decrypt messages others sent to you with your private key - Sign / Verify message signature Best of all, encryption and decryption of messages can be done directly in the iMessage app. When using the in-app extension, you no longer have to send a long piece of string, the encrypted message is embedded into an iMessage object so the other side can just click and decrypt.

Write a secret. Share one link. It reads once and burns. BurnPony encrypts your note on your phone before anything is sent. The server stores only ciphertext it cannot read, the decryption key travels in a part of the link that browsers never transmit, and the recipient needs nothing but a browser. No app on their side, no account on yours. WHAT IT DOES One link, any recipient, any device with a browser. View limits from 1 to 100, expiry from 5 minutes to 30 days, an optional auto-hide timer after reveal. Optional passphrase as a second factor, shared through a different channel than the link. Read receipts, honestly: the recipient is told before they open. No silent tracking, ever. Labels that never leave your phone: name a note "wifi password for mom" and the read notification says so, while the server knows nothing. Sent Notes: live status, view counts, change the expiration after sending, burn early with a swipe. The recipient page speaks nine languages, following the reader's browser. WHY YOU CAN CHECK INSTEAD OF TRUST The entire system is open source: this app, the server, and the recipient page, with a written protocol specification and cross-implementation test vectors. The note page is byte-reproducible from its published source, so View Source is a real audit, not a gesture. You can even run your own server and point the app at it from Settings. HONEST LIMITS Self-destruction limits exposure; it cannot un-share. A recipient can always copy or photograph a revealed note, and BurnPony says so on the note page itself, because a privacy tool that overpromises is worse than none.
