SHA256

Single message hashing

Initial Functions

public static Byte[] ComputeHash(Byte[] Message) 

Example Code

Byte[] RandomMessage = SodiumRNG.GetRandomBytes(128);
Byte[] ComputedHash = SodiumHashSHA256.ComputeHash(RandomMessage);

Multiple message hashing

Initial Functions

public static Byte[] InitializeState()
public static Byte[] UpdateState(Byte[] State, Byte[] Message)
public static Byte[] ComputeHashForFinalizedState(Byte[] State)

Example Code

Byte[] RandomMessage1 = SodiumRNG.GetRandomBytes(128);
Byte[] RandomMessage2 = SodiumRNG.GetRandomBytes(128);
Byte[] RandomMessage3 = SodiumRNG.GetRandomBytes(128);
Byte[] State = SodiumHashSHA256.InitializeState();
State = SodiumHashSHA256.UpdateState(State, RandomMessage1);
State = SodiumHashSHA256.UpdateState(State, RandomMessage2);
State = SodiumHashSHA256.UpdateState(State, RandomMessage3);
Byte[] ComputedHash = SodiumHashSHA256.ComputeHashForFinalizedState(State);

SHA512

Single message hashing

Initial Function

public static Byte[] ComputeHash(Byte[] Message) 

Example Code

Byte[] RandomMessage = SodiumRNG.GetRandomBytes(128);
Byte[] ComputedHash = SodiumHashSHA512.ComputeHash(RandomMessage);

Multiple message hashing

Initial Functions

public static Byte[] InitializeState()
public static Byte[] UpdateState(Byte[] State, Byte[] Message)

Byte[] RandomMessage2 = SodiumRNG.GetRandomBytes(128);
Byte[] RandomMessage3 = SodiumRNG.GetRandomBytes(128);
Byte[] State = SodiumHashSHA512.InitializeState();
State = SodiumHashSHA512.UpdateState(State, RandomMessage1);
State = SodiumHashSHA512.UpdateState(State, RandomMessage2);
