SymmetricAlgorithm.Create Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Creates a cryptographic object used to perform the symmetric algorithm.

Overloads

Create()	Obsolete. Creates a default cryptographic object used to perform the symmetric algorithm.
Create(String)	Obsolete. Creates the specified cryptographic object used to perform the symmetric algorithm.

Create()

Source:

SymmetricAlgorithm.cs

Caution

The default implementation of this cryptography algorithm is not supported.

Creates a default cryptographic object used to perform the symmetric algorithm.

public:
 static System::Security::Cryptography::SymmetricAlgorithm ^ Create();

[System.Obsolete("The default implementation of this cryptography algorithm is not supported.", DiagnosticId="SYSLIB0007", UrlFormat="https://aka.ms/dotnet-warnings/{0}")]
public static System.Security.Cryptography.SymmetricAlgorithm Create ();

[<System.Obsolete("The default implementation of this cryptography algorithm is not supported.", DiagnosticId="SYSLIB0007", UrlFormat="https://aka.ms/dotnet-warnings/{0}")>]
static member Create : unit -> System.Security.Cryptography.SymmetricAlgorithm

Public Shared Function Create () As SymmetricAlgorithm

Returns

SymmetricAlgorithm

A default cryptographic object used to perform the symmetric algorithm.

Attributes

ObsoleteAttribute

Exceptions

PlatformNotSupportedException

.NET Core 2.0 - 3.1 and .NET 5 and later: In all cases.

Remarks

This method is obsolete in .NET 5 and later versions.

We recommend that you specify the algorithm by calling the Create(String) overload of this method.

Caution

Cryptographic factory methods accepting an algorithm name are obsolete. Use the parameterless Create factory method on the algorithm type instead.

Creates the specified cryptographic object used to perform the symmetric algorithm.

public:
 static System::Security::Cryptography::SymmetricAlgorithm ^ Create(System::String ^ algName);
