HashAlgorithm.HashSize Property

Updated: December 2008

Gets the size, in bits, of the computed hash code.

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

public virtual int HashSize { get; }

Property Value

Type: System.Int32
The size, in bits, of the computed hash code.

The size of the hash code depends on the hash algorithm it is computed for. For example, the size of the hash for the HMACSHA384 algorithm is 384 bits, and the size of the hash for the HMACSHA256 algorithm is 256 bits. You can obtain the size of the hash in bits by calling the HashSize property. For more information about hash codes, see Ensuring Data Integrity with Hash Codes.
