SHA256.TryHashData(ReadOnlySpan<Byte>, Span<Byte>, Int32) 方法

定义

尝试使用 SHA256 算法计算数据的哈希值。Attempts to compute the hash of data using the SHA256 algorithm.

public:
 static bool TryHashData(ReadOnlySpan<System::Byte> source, Span<System::Byte> destination, [Runtime::InteropServices::Out] int % bytesWritten);
public static bool TryHashData (ReadOnlySpan<byte> source, Span<byte> destination, out int bytesWritten);
static member TryHashData : ReadOnlySpan<byte> * Span<byte> * int -> bool
Public Shared Function TryHashData (source As ReadOnlySpan(Of Byte), destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean

参数

source
ReadOnlySpan<Byte>

要进行哈希处理的数据。The data to hash.

destination
Span<Byte>

要接收哈希值的缓冲区。The buffer to receive the hash value.

bytesWritten
Int32

此方法返回时,为写入 destination 的字节总数。When this method returns, the total number of bytes written into destination.

返回

Boolean

如果 destination 太小,无法容纳计算所得的哈希,则为 false;否则为 truefalse if destination is too small to hold the calculated hash, true otherwise.
