RSA.TryHashData Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

RSA.cs

Attempts to compute the hash of the provided data by using the specified algorithm, writing the results 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 buffer to receive the hash value.

hashAlgorithm

HashAlgorithmName

The algorithm to use in hash the data.

bytesWritten

Int32

When this method returns, the total number of bytes written into destination. This parameter is treated as uninitialized.

Returns

Boolean

true if destination is long enough to receive the hash value; otherwise, false.

Remarks

The default implementation of this method calls HashData(Byte[], Int32, Int32, HashAlgorithmName) and copies the result to destination. Derived types should override this method to avoid the intermediate array creation.
