C# 클래스 DotNetCrypt.ManagedTransformBase

An abstract base class for managed implementations of ICryptoTransform.

This class deals with the various forms of padding available. Unlike the classes built into the .NET framework, however, for modes which effectively operate in stream cipher mode (CFB, OFB), it is permissible to encrypt a message which is not an exact number of bytes without specifying a padding mode other than System.Security.Cryptography.PaddingMode.None

It also takes into account the cipher mode to be used. For increased compatibility with other systems, counter mode (CTR) is also supported via the ExtendedCipherMode enumeration.

메소드	설명
Clear ( ) : void	Releases all resources used by the ManagedTransformBase class.
Dispose ( ) : void	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
TransformBlock ( byte inputBuffer, int inputOffset, int inputCount, byte outputBuffer, int outputOffset ) : int	Transforms the specified region of the input byte array and copies the resulting transform to the specified region of the output byte array.
TransformFinalBlock ( byte inputBuffer, int inputOffset, int inputCount ) : byte[]	Transforms the specified region of the specified byte array.

보호된 메소드들

메소드	설명
DecryptBlock ( byte block ) : void	Decrypts a single block of bytes, writing the result into the provided array.
Dispose ( bool disposing ) : void	Dispose(bool disposing) executes in two distinct scenarios. If disposing equals true, the method has been called directly or indirectly by a user's code. Managed and unmanaged resources can be disposed. If disposing equals false, the method has been called by the runtime from inside the finalizer and you should not reference other objects. Only unmanaged resources can be disposed.
EncryptBlock ( byte block ) : void	Encrypts a single block of bytes, writing the result into the provided array.
ManagedTransformBase ( ISymmetricAlgorithm algorithm, byte rgbIv, TransformDirection transformDirection, Endianness endianness ) : System	Creates a new managed transform instance, reading necessary setting values from the provided ISymmetricAlgorithm instance.
Reset ( ) : void	Clears all potentially sensitive data stores.

Dispose() 보호된 메소드

Dispose(bool disposing) executes in two distinct scenarios. If disposing equals true, the method has been called directly or indirectly by a user's code. Managed and unmanaged resources can be disposed.

If disposing equals false, the method has been called by the runtime from inside the finalizer and you should not reference other objects. Only unmanaged resources can be disposed.
