string

Counter

The FIPS 186-4 A.1.1.2 counter (evidence only).

public int Counter { get; }

Property Value

int

Hash

The FIPS 186-4 generation hash (evidence only).

public NistHashAlgorithm Hash { get; }

Property Value

NistHashAlgorithm

Methods

Fips186Evidence(ReadOnlySpan<byte>, int, NistHashAlgorithm)

Validate the parameters by replaying FIPS 186-4 Appendix A.1.1.3 probable-prime generation from its seed, counter, and hash, and by testing p and q for primality.

public static FfcDomainAssurance Fips186Evidence(ReadOnlySpan<byte> seed, int counter, NistHashAlgorithm hash)

Parameters

seed ReadOnlySpan<byte>

counter int

hash NistHashAlgorithm

Returns

FfcDomainAssurance

TrustedAuthority(string)

Assurance obtained from a trusted party (SP 800-56A §5.5.2). Only the structural checks run: sizes, q | p - 1, and g of order q. Primality is taken from the trusted party.
