Types

type DecryptReader

type DecryptReader struct {
	// contains filtered or unexported fields
}

func NewDecryptReader

func NewDecryptReader(key []byte, src io.Reader) (*DecryptReader, error)

func (*DecryptReader) Read

func (r *DecryptReader) Read(p []byte) (int, error)

type DecryptReaderAt

type DecryptReaderAt struct {
	// contains filtered or unexported fields
}

func NewDecryptReaderAt

func NewDecryptReaderAt(key []byte, src io.ReaderAt, size int64) (*DecryptReaderAt, error)

func (*DecryptReaderAt) ReadAt

func (r *DecryptReaderAt) ReadAt(p []byte, off int64) (n int, err error)

type EncryptReader

type EncryptReader struct {
	// contains filtered or unexported fields
}

func NewEncryptReader

func NewEncryptReader(key []byte, src io.Reader) (*EncryptReader, error)

func (*EncryptReader) Read

func (r *EncryptReader) Read(p []byte) (int, error)

type EncryptWriter

type EncryptWriter struct {
	// contains filtered or unexported fields
}

func NewEncryptWriter

func NewEncryptWriter(key []byte, dst io.Writer) (*EncryptWriter, error)

func (*EncryptWriter) Close

func (w *EncryptWriter) Close() error

Close flushes the last chunk. It does not close the underlying Writer.

func (*EncryptWriter) Write

func (w *EncryptWriter) Write(p []byte) (n int, err error)
