Syntax

public sealed class SeekableCryptoStream : CryptoStream, IAsyncDisposable, IDisposable

Constructors

SeekableCryptoStream(Stream, ICryptoTransform, CryptoStreamMode, bool)

Creates a new SeekableCryptoStream instance.

Declaration

public SeekableCryptoStream(Stream innerStream, ICryptoTransform cryptoTransform, CryptoStreamMode mode, bool leaveOpen)

Parameters

Type	Name	Description
Stream	innerStream	The inner stream to encrypt or decrypt.
ICryptoTransform	cryptoTransform	The encryption for the stream.
CryptoStreamMode	mode	The read/write mode for the stream.
bool	leaveOpen	Whether this instance should take ownership of the inner stream.

Properties
