Padding Property

SymmetricAlgorithm.Padding Property

Gets or sets the padding mode used in the symmetric algorithm.

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

public virtual PaddingMode Padding { get; set; }

Property Value

Type: System.Security.Cryptography.PaddingMode
The padding mode used in the symmetric algorithm. The default is PaddingMode.PKCS7.

ExceptionCondition
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 the PaddingMode enumeration for a description of specific modes.
