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

定义

命名空间:
System.Security.Cryptography
程序集:
System.Security.Cryptography.Algorithms.dll

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 true。false if destination is too small to hold the calculated hash, true otherwise.
