Interface IShareAuthenticator

Namespace

PostQuantum.SecretSharing

Assembly

PostQuantum.SecretSharing.dll

A dealer-side signer that authenticates the canonical bytes of a share.

public interface IShareAuthenticator

Remarks

The signature binds the dealer's public key together with all share metadata (keys 0–10 of the format), so a verifier with the pinned public key can detect any tampering or substitution. v1 ships one implementation, MlDsa65ShareAuthenticator (net10.0).
