## Remarks
Hash functions are fundamental to modern cryptography. These functions map binary strings of an arbitrary length to small binary strings of a fixed length, known as hash values. A cryptographic hash function has the property that it is computationally infeasible to find two distinct inputs that hash to the same value. Hash functions are commonly used with digital signatures and for data integrity.
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 the corresponding data also matches. Small changes to the data result in large unpredictable changes in the hash.
Due to collision problems with SHA1, Microsoft recommends a security model based on SHA256 or better.
## Examples
The following code example computes the <xref:System.Security.Cryptography.SHA256> hash for an array. This example assumes that there is a predefined byte array `dataArray[]`. <xref:System.Security.Cryptography.SHA256> is a derived class of <xref:System.Security.Cryptography.HashAlgorithm>.

## Examples
The following example computes the <xref:System.Security.Cryptography.SHA256> hash value of a string and returns the hash as a 64-character, hexadecimal-formatted string. The hash string created by this code example is compatible with any SHA256 hash function (on any platform) that creates a 64-character, hexadecimal-formatted hash string.

## Remarks
This method is obsolete in .NET 5 and later versions.
By default, this overload uses the <xref:System.Security.Cryptography.SHA1CryptoServiceProvider> implementation of a hash algorithm. If you want to specify a different implementation, use the <xref:System.Security.Cryptography.HashAlgorithm.Create%28System.String%29> overload, which lets you specify an algorithm name, instead. The cryptography configuration system defines the default implementation of <xref:System.Security.Cryptography.HashAlgorithm>.
Due to collision problems with SHA1, Microsoft recommends a security model based on SHA256 or better.

## Remarks
This method is called by the public `Dispose()` method and the <xref:System.Object.Finalize> method, if it has been overridden. `Dispose()` invokes this method with the `disposing` parameter set to `true`. `Finalize` invokes this method with `disposing` set to `false`.
When the `disposing` parameter is `true`, this method releases all resources held by any managed objects that this <xref:System.Security.Cryptography.HashAlgorithm> references. This method invokes the `Dispose()` method of each referenced object.
