CryptoConfig::MapNameToOID Method

Gets the object identifier (OID) of the algorithm corresponding to the specified simple name.

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

static String^ MapNameToOID(
	String^ name


Type: System::String

The simple name of the algorithm for which to get the OID.

Return Value

Type: System::String
The OID of the specified algorithm.


The name parameter is nullptr.

For a list of simple names recognized by this class, see CryptoConfig.

The following code example demonstrates how to call the MapNameToOID method to retrieve an object identifier (OID) from the string name of the SHA1 algorithm. This code example is part of a larger example provided for the CryptoConfig class.

String^ sha1Oid = CryptoConfig::MapNameToOID( L"SHA1" );
