Initializes a new instance of the SHA256Managed class using the managed library.
public SHA256Managed ();
Public Sub New ()
The Federal Information Processing Standards (FIPS) security setting is enabled. This implementation is not part of the Windows Platform FIPS-validated cryptographic algorithms.
The hash is used as a unique value of fixed size representing a large amount of data. Hashes of two sets of data should match if and only if the corresponding data also matches. Small changes to the data result in large unpredictable changes in the hash.
The hash size for the SHA256Managed algorithm is 256 bits.
If you enable the following security setting either in the Local Security Policy or as part of Group Policy you will get an InvalidOperationException when you attempt to use this constructor:
