CryptographicOperations.TryHashData Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

CryptographicOperations.cs

Attempts to compute the hash of data.

public:
 static bool TryHashData(System::Security::Cryptography::HashAlgorithmName hashAlgorithm, ReadOnlySpan<System::Byte> source, Span<System::Byte> destination, [Runtime::InteropServices::Out] int % bytesWritten);

public static bool TryHashData (System.Security.Cryptography.HashAlgorithmName hashAlgorithm, ReadOnlySpan<byte> source, Span<byte> destination, out int bytesWritten);

static member TryHashData : System.Security.Cryptography.HashAlgorithmName * ReadOnlySpan<byte> * Span<byte> * int -> bool

Public Shared Function TryHashData (hashAlgorithm As HashAlgorithmName, source As ReadOnlySpan(Of Byte), destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean

Parameters

hashAlgorithm

HashAlgorithmName

The algorithm used to compute the hash.

source

ReadOnlySpan<Byte>

The data to hash.

destination

Span<Byte>

The buffer to receive the hash value.

bytesWritten

Int32

When this method returns, the total number of bytes written into destination.

Returns

Boolean

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

Exceptions

ArgumentException

hashAlgorithm has a Name that is empty.

ArgumentNullException

hashAlgorithm has a Name that is null.

PlatformNotSupportedException

hashAlgorithm specifies a hash algorithm not supported by the current platform.

CryptographicException

hashAlgorithm specifies an unknown hash algorithm.
