SharePolicy(int, int)

A threshold policy: split a secret into TotalShares shares such that any Threshold of them reconstruct it and any fewer reveal nothing.

public SharePolicy(int Threshold, int TotalShares)

Parameters

Threshold int

The quorum size k required to reconstruct. Must satisfy 2 ≤ k ≤ TotalShares. k = 1 is forbidden: every share would equal the secret, which is security theater rather than secret sharing.

TotalShares int

The number of shares n to issue. Must satisfy k ≤ n ≤ 255 (x-coordinates live in GF(2^8) and x=0 is reserved for the secret).

Properties

Threshold

public int Threshold { get; init; }

Property Value

TotalShares

The number of shares n to issue. Must satisfy k ≤ n ≤ 255 (x-coordinates live in GF(2^8) and x=0 is reserved for the secret).

public int TotalShares { get; init; }

Property Value
