Institutional-Grade Cryptography

The foundation of Inheribase's Zero-Knowledge guarantee is the Digital Airlock. Everything happens on your device.

Before any piece of your data—be it a document, a seed phrase, or a personal letter—leaves your computer or phone, it is encrypted locally using the Web Crypto API with AES-256-GCM (Advanced Encryption Standard with Galois/Counter Mode).

This is the cryptographic standard used by banks, governments, and military institutions worldwide. Even if our databases were completely exposed, the attackers would find nothing but mathematically irreducible ciphertext. We do not hold your encryption keys, meaning we could not read your data even if compelled to do so.

How do you safely distribute keys without exposing the vault? By mathematically splitting them into pieces.

When you assign Guardians, Inheribase uses Shamir's Secret Sharing (SSS) to split your master decryption key into distinct cryptographic shards. Each Guardian receives a single shard.

Crucially, no single shard reveals anything about your key or your data. A threshold (e.g., 2 out of 3, or 3 out of 5) of these shards must be combined to reconstruct the original key. This ensures that no individual Guardian can maliciously access your vault, while protecting your data even if some Guardians lose their keys.

Legacy cloud storage treats your data as a liability waiting to be deleted. We treat it as heritage.

Once your data is encrypted, it isn't simply placed on a typical AWS S3 bucket where a missed credit card payment results in immediate deletion. Instead, the encrypted ciphertext is saved to the Arweave Network.

Arweave utilizes an endowment structure where you pay once for data storage, and the interest accrued pays for the storage cost virtually forever (estimated at 200+ years). In combination with the Base Mainnet for immutable release logic, your vault effectively outlives Inheribase itself.
