Fields

SeedLen

The length of the seed used for deterministic random byte generation.

public const int SeedLen = 32

Field Value

int

Methods

Close()

Closes the random number generator.

public static void Close()

Exceptions

LibSodiumException

Thrown when randombytes_close() fails.

Fill(Span<byte>)

Fills the specified buffer with random bytes.

public static void Fill(Span<byte> buffer)

Parameters

buffer Span<byte>

The buffer to fill with random bytes.

FillDeterministic(Span<byte>, ReadOnlySpan<byte>)

Fills the specified buffer with deterministic random bytes based on the provided seed. It produces the same sequence of random bytes for the same seed.

public static void FillDeterministic(Span<byte> buffer, ReadOnlySpan<byte> seed)

Parameters

buffer Span<byte>

The buffer to fill with deterministic random bytes.

seed ReadOnlySpan<byte>

The seed used for deterministic random byte generation.

Exceptions

ArgumentException

Thrown when the seed length is not equal to SeedLen.

GetUInt32()

Gets a random unsigned 32-bit integer.

public static uint GetUInt32()

Returns

uint

A random unsigned 32-bit integer.

GetUInt32(uint)

Gets a random unsigned 32-bit integer less than the specified upper bound.

public static uint GetUInt32(uint upperBound)

Parameters

upperBound uint

The upper bound (exclusive) for the random number.

Returns

uint

A random unsigned 32-bit integer less than upperBound.

Stir()

Stirs the random number generator to ensure randomness.

public static void Stir()
