RSA.TryExportRSAPrivateKeyPem(Span<Char>, Int32) Method

Definition

Attempts to export the current key in the PEM-encoded PKCS#1 RSAPrivateKey format into a provided buffer.

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

Parameters

destination
Span<Char>

The character span to receive the PEM-encoded PKCS#1 RSAPrivateKey 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 PKCS#1 RSAPrivateKey will begin with -----BEGIN RSA PRIVATE KEY----- and end with -----END RSA 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.
