RSA.TryExportPkcs8PrivateKey(Span<Byte>, Int32) 方法
定义
尝试以 PKCS#8 PrivateKeyInfo 格式将当前密钥导出到所提供的缓冲区。Attempts to export the current key in the PKCS#8 PrivateKeyInfo format into a provided buffer.
public:
override bool TryExportPkcs8PrivateKey(Span<System::Byte> destination, [Runtime::InteropServices::Out] int % bytesWritten);
public override bool TryExportPkcs8PrivateKey (Span<byte> destination, out int bytesWritten);
override this.TryExportPkcs8PrivateKey : Span<byte> * int -> bool
Public Overrides Function TryExportPkcs8PrivateKey (destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean
参数
接收 PKCS#8 PrivateKeyInfo 数据的字节范围。The byte span to receive the PKCS#8 PrivateKeyInfo data.
- bytesWritten
- Int32
此方法返回时,包含一个指示写入 destination 的字节数的值。When this method returns, contains a value that indicates the number of bytes written to destination. 该参数未经初始化即被处理。This parameter is treated as uninitialized.
返回
如果 destination 具有足够的大小以接收输出,则为 true;否则为 false。true if destination is big enough to receive the output; otherwise, false.
例外
未能导出密钥。The key could not be exported.
