SymmetricAlgorithm.BlockSize Property

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

SymmetricAlgorithm.cs

Gets or sets the block size, in bits, of the cryptographic operation.

public:
 virtual property int BlockSize { int get(); void set(int value); };

public virtual int BlockSize { get; set; }

member this.BlockSize : int with get, set

Public Overridable Property BlockSize As Integer

Property Value

Int32

The block size, in bits.

Exceptions

CryptographicException

The block size is invalid.

Remarks

The block size is the basic unit of data that can be encrypted or decrypted in one operation. Messages longer than the block size are handled as successive blocks; messages shorter than the block size must be padded with extra bits to reach the size of a block. Valid block sizes are determined by the symmetric algorithm used.
