What is Shamir's Secret Sharing in Cosmo Crypt?

Shamir's Secret Sharing (SSS) is a mathematically proven threshold cryptography algorithm developed by Adi Shamir. It divides a master secret into multiple distinct shares (guardian shards). A defined quorum of shards can mathematically reconstruct the original master secret, while fewer shards reveal zero information.

How many guardian shards are required for reconstruction?

Cosmo Crypt uses a standard (3, 3) threshold quorum. You must provide all 3 guardian shards to reconstruct the master password in the Galois Field.

Does Cosmo Crypt store or upload my shards or reconstructed password?

No. All Galois Field arithmetic occurs strictly client-side inside your browser memory. No network packets are dispatched, no shards are sent to servers, and zero data is written to localStorage.

What is Byzantine Fault Detection in Shamir Reconstruction?

Byzantine fault detection audits shards for mathematical consistency. If any shard was altered, corrupted in transit, or generated from a mismatched polynomial, the reconstruction engine rejects the operation to prevent false secret output.
