DSA.TryHashData Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

DSA.cs

Attempts to compute the hash value of the provided data into a provided buffer.

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

protected virtual bool TryHashData (ReadOnlySpan<byte> data, Span<byte> destination, System.Security.Cryptography.HashAlgorithmName hashAlgorithm, out int bytesWritten);

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

Protected Overridable Function TryHashData (data As ReadOnlySpan(Of Byte), destination As Span(Of Byte), hashAlgorithm As HashAlgorithmName, ByRef bytesWritten As Integer) As Boolean

Parameters

data

ReadOnlySpan<Byte>

The data to be hashed.

destination

Span<Byte>

The byte span to receive the hash value.

hashAlgorithm

HashAlgorithmName

The name of the hash algorithm to use.

bytesWritten

Int32

When this method returns, contains a value that indicates the number of bytes written to destination.

Returns

Boolean

true if destination is large enough to receive the result; otherwise, false.

Remarks

The default implementation of this method is to call HashData(Byte[], Int32, Int32, HashAlgorithmName) and copy the result to destination.

Derived types should override this method to avoid the intermediate array creation.
