[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Represents the block size, in bits, of the cryptographic operation.

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

'Declaration
Protected BlockSizeValue As Integer

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.

This field is accessed through the BlockSize property.
