Discover Superbacked

Possibly the world’s most advanced backup and succession planning app

• Powered by state of the art open source cryptography

  Standard and distributed backups are encrypted using Blockcrypt, an open source encryption scheme based on AES-256-GCM that provides plausible deniability (watch episode).

  Distributed backups are encrypted using sss, one of the most secure implementations of Shamir Secret Sharing developed by Amber Sprenkels (a post-quantum computing PhD student in the Netherlands) before being encrypted (again) using Blockcrypt.

  Blockcrypt encryption keys are derived using Argon2, a brute-force-resistent password-hashing function that won the 2015 Password Hashing Competition.

  Fun fact: it would theoretically take 10,539,639 years to brute-force Superbacked-generated 5-word passphrase using MacBook Air with M1 chip (we’re not kidding around).

• Cryptographically-signed releases

  Releases are PGP-signed by Sun and cryptographically signed and notarized (scanned for malware) by Apple (Superbacked isn’t a bootleg operation).

• Transparent by design

  Superbacked is an Electron app therefore, even though its source code is proprietary, it can be audited (watch episode).

  If you find a security vulnerability, please get in touch.

• Trusted

  Superbacked is developed by Sun, a privacy and security researcher and senior full stack developer followed by over 38,000 people on YouTube.
