SeedSequence.FillBytes Method

public virtual void FillBytes(
	Span<byte> buffer
)

Public Overridable Sub FillBytes ( 
	buffer As Span(Of Byte)
)

public:
virtual void FillBytes(
	Span<unsigned char> buffer
)

abstract FillBytes : 
        buffer : Span<byte> -> unit 
override FillBytes : 
        buffer : Span<byte> -> unit 

Parameters

buffer  Span<Byte>

The span to fill with entropy bytes.

This method provides a deterministic byte-stream API using little-endian byte order for expanding 32-bit values. This is particularly useful for counter-based RNGs and cipher-based wrappers that require byte-level initialization (e.g., ChaCha keys/nonces).

The method fills as many complete 32-bit words as possible, then handles any remaining 1-3 bytes by extracting them from a final 32-bit word.
