Superbacked is a secret management platform used to back up and pass on sensitive data in the context of succession planning.

Powered by state of the art open source cryptography
Superbacked standard and distributed backups are encrypted using Blockcrypt, an open source encryption scheme based on AES-256-GCM that provides plausible deniability (watch episode).
Superbacked distributed backups are encrypted using sss, one of the most secure implementations of Shamir Secret Sharing developed by Amber Sprenkels (a post-quantum cryptography PhD) 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 source-available releases
Superbacked releases are PGP-signed by Sun and cryptographically signed and notarized (scanned for malware) by Apple.
Transparent by design
Superbacked is an Electron app therefore, even though its source code is packaged, it can be easily extracted and audited (watch episode).
When using Superbacked for personal use only, building app from source code is allowed under end-user license agreement.
