ECAlgorithm.TryExportECPrivateKeyPem(Span<Char>, Int32) Method

Definition

Attempts to export the current key in the PEM-encoded ECPrivateKey format into a provided buffer.

public:
 bool TryExportECPrivateKeyPem(Span<char> destination, [Runtime::InteropServices::Out] int % charsWritten);
public bool TryExportECPrivateKeyPem (Span<char> destination, out int charsWritten);
member this.TryExportECPrivateKeyPem : Span<char> * int -> bool
Public Function TryExportECPrivateKeyPem (destination As Span(Of Char), ByRef charsWritten As Integer) As Boolean

Parameters

destination
Span<Char>

The character span to receive the PEM-encoded ECPrivateKey data.

charsWritten
Int32

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

Returns

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

Exceptions

The key could not be exported.

Remarks

A PEM-encoded ECPrivateKey will begin with -----BEGIN EC PRIVATE KEY----- and end with -----END EC PRIVATE KEY-----, with the base64 encoded DER contents of the key between the PEM boundaries.

          The PEM is encoded according to the IETF RFC 7468 "strict"
          encoding rules.
