<summary>Computes the <see cref="T:System.Security.Cryptography.SHA256" /> hash for the input data using the managed library.</summary>
<remarks>
<format type="text/markdown"><![CDATA[
## Remarks
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 <xref:System.Security.Cryptography.SHA256Managed> algorithm is 256 bits.
## Examples
The following example calculates the SHA-256 hash for all files in a directory.

This method is not called by application code.
This abstract method performs the hash computation. Every write to the cryptographic stream object passes the data through this method. For each block of data, this method updates the state of the hash object so a correct hash value is returned at the end of the data stream.

## Remarks
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 <xref:System.Security.Cryptography.SHA256Managed> algorithm is 256 bits.
