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

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

public virtual int BlockSize { get; set; }

Property Value

Type: System.Int32
The block size, in bits.


The block size is invalid.

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.
