]CryptoStream class
Stream implementation that wraps existing stream with a cryptographic function. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.
class CryptoStream : public System::IO::Stream
Methods
| Method | Description |
|---|---|
| Close() override | Closes connection. |
| CryptoStream(const SharedPtr<System::IO::Stream>&, const SharedPtr<ICryptoTransform>&, CryptoStreamMode) | Constructor. |
| Flush() override | Empties buffer into wrapped stream. Does nothing as transform algorithm can be still waiting for more data. |
| FlushFinalBlock() | Writes the data which is still in the buffer to stream. |
| get_CanRead() const override | Checks if stream is readable. |
| get_CanSeek() const override | Checks if stream is seekable. |
| get_CanWrite() const override | Checks if stream is writable. |
| get_Length() const override | Gets length of stream. Not supported. |
| get_Position() const override | Gets current position in stream. Not supported. |
| Read(const ArrayPtr<uint8_t>&, int32_t, int32_t) override | Reads data from stream. |
| Read(const System::Details::ArrayView<uint8_t>&, int32_t, int32_t) override | Reads data from stream. |
| Seek(int64_t, IO::SeekOrigin) override | Seeks position in stream. Not supported. |
| set_Position(int64_t) override | Seeks position in stream. Not supported. |
| SetLength(int64_t) override | Seeks size of stream. Not supported. |
| Write(const ArrayPtr<uint8_t>&, int32_t, int32_t) override | Writes data to stream. |
| Write(const System::Details::ArrayView<uint8_t>&, int32_t, int32_t) override | Writes data to stream. |
Fields
| Field | Description |
|---|---|
| static Null | A stream with no underlying storage. |
