DSACryptoServiceProvider.KeySize Property

Gets the size of the key used by the asymmetric algorithm in bits.

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

abstract KeySize : int with get 
override KeySize : int with get

Property Value

Type: System.Int32
The size of the key used by the asymmetric algorithm.

This algorithm supports key lengths from 512 bits to 1024 bits in increments of 64 bits.

The DSACryptoServiceProvider class does not allow you to change key sizes using the KeySize property. Any value written to this property will fail to update the property without error. To change the key size, use one of the constructor overloads.
