How does Privnote protect your secrets and encrypt every chat?

Privnote offers a clever solution for keeping your private communications truly confidential through encrypted self-destructing notes. Unlike standard messaging apps that persist and replicate data indefinitely, Privnote embraces ephemerality using end-to-end encryption tied to a unique URL for each note. Once the intended recipient views the content, it’s automatically wiped from Privnote’s servers to leave no trail behind.

Automated encryption

Privnote handles all encryption automatically in the background when you create a new note. Your message is secured using AES-256, the same symmetric algorithm used by governments to encrypt top-secret data. It operates with a 256-bit key for over 1.1 x 10^77 possible combinations. They never see or store the unencrypted message or encryption key on their servers. The key is generated uniquely to encrypt each note’s payload and then destroyed after use. It ensures only the intended recipient decrypt and view the content once.

No data at rest

how to protect text messages? Since the encrypted payload is deleted after the first view, there is no data at rest for hackers to access. Even if Privnote’s servers were compromised, the hacker would only get encrypted cipher text tied to destroyed keys. Your private messages stay private. Privnote allows you to set an optional password that encrypts notes with a second layer of protection. The password functions as a decryption key needed to read your note. This role-based encryption lets you control precisely who accesses the content.

Self-destruction by default

Ephemerality is central to Privnote’s functionality. After a note is accessed once via its unique URL, the encrypted payload is automatically deleted from their servers forever. No copies of your private communication persist digitally. By keeping the password to unlock a note yourself, control remains in your hands. If you don’t share the password, the note remains encrypted and useless without it. It prevents any unintended access. Privnote’s tight encryption binds each note to a single access URL for the recipient. Combined with automated deletion, this minimizes the attack surface. A typical messaging inbox provides countless messages for hackers to target. Privnote closes this exposure window.

No message history

Your conversations are ephemeral by design. Unlike messaging apps that compile exhaustive histories, Privnote maintains no local or cloud storage of your notes. There is no persistent message history for hackers or subpoenas to exploit. By avoiding login accounts, Privnote prevents associating notes with your identity via account metadata. The anonymous self-destructing URLs contain no metadata to expose who created a note. It adds another layer of privacy. Privnote uses HTTPS encryption during note transmission. It protects your message from interception or surveillance while in motion between its servers and the recipient. Client devices and networks must also be secure to prevent local copying of notes before deletion.

Limitations persist

Despite these protections, some risks remain. Recipients could screenshot or copy notes before they self-destruct. Client device malware could also monitor note content locally. Accidental misdirected notes can’t be undone or recalled. Privnote’s automated encryption, role-based access control, ephemerality, and minimal attack surface provide a powerful solution for communicating privately in the modern era. The same conversation over normal messaging or email leaves a permanent vulnerable digital trail.
