Create()

- Source:
- SHA256.cs
Creates an instance of the default implementation ofSHA256.
public: static System::Security::Cryptography::SHA256 ^ Create();public static System.Security.Cryptography.SHA256 Create();static member Create : unit -> System.Security.Cryptography.SHA256Public Shared Function Create () As SHA256Returns
A new instance ofSHA256. On the .NET Framework, this method creates an instance of theSHA256Managed class if FIPS mode is not active; if FIPS mode is active, it creates an instance of theSHA256Cng class. On .NET Core, it returns an instance of a private class derived fromSHA256.
Exceptions
On the .NET Framework 4.6.1 and earlier versions only: The algorithm was used with Federal Information Processing Standards (FIPS) mode enabled, but is not FIPS compatible.

Returns
A new instance ofSHA256 using the specified implementation.

Exceptions
On the .NET Framework only: FIPS mode is enabled, buthashName requestsSHA256Managed, which is not FIPS compatible.
Remarks
The .NET Framework includes the implementations and their associated hashName values:
| Implementation | hashName |
|---|---|
| SHA256Managed | SHA256 SHA-256 System.Security.Cryptography.SHA256 |
| SHA256Cng | System.Security.Cryptography.SHA256Cng |
| SHA256CryptoServiceProvider | System.Security.Cryptography.SHA256CryptoServiceProvider |
