AsymmetricAlgorithm.TryExportPkcs8PrivateKey(Span<Byte>, Int32) Method

Definition

Assemblies:: System.Security.Cryptography.Primitives.dll, netstandard.dll, mscorlib.dll

When overridden in a derived class, attempts to export the current key in the PKCS#8 PrivateKeyInfo format into a provided buffer.

public:
 virtual bool TryExportPkcs8PrivateKey(Span<System::Byte> destination, [Runtime::InteropServices::Out] int % bytesWritten);

public virtual bool TryExportPkcs8PrivateKey (Span<byte> destination, out int bytesWritten);

abstract member TryExportPkcs8PrivateKey : Span<byte> * int -> bool
override this.TryExportPkcs8PrivateKey : Span<byte> * int -> bool

Public Overridable Function TryExportPkcs8PrivateKey (destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean

The byte span to receive the PKCS#8 PrivateKeyInfo data.

When this method returns, contains a value that indicates the number of bytes written to destination. This parameter is treated as uninitialized.

Boolean

true if destination is big enough to receive the output; otherwise, false.

CryptographicException

The key could not be exported.

NotImplementedException

A derived type has not overriden this member.

Because algorithm-specific support is required to produce this data format, TryExportPkcs8PrivateKey throws a NotImplementedException by default.
