Public Overridable Property Padding As PaddingMode
public virtual PaddingMode Padding {get; set;}

public: __property virtual void set_Padding(PaddingMode);

Property Value

The padding mode used in the symmetric algorithm.


Exception Type Condition
CryptographicException The padding mode is not one of the PaddingMode values.


Most plain text messages do not consist of a number of bytes that completely fill blocks. Often, there are not enough bytes to fill the last block. When this happens, a padding string is added to the text. For example, if the block length is 64 bits and the last block contains only 40 bits, 24 bits of padding are added. See PaddingMode for a description of specific modes.
