Public Shared Function MapNameToOID (name As String) As String

Parameters

name: String

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

Returns

String

The OID of the specified algorithm.

Attributes: UnsupportedOSPlatformAttribute

Exceptions

ArgumentNullException

The name parameter is null.

Examples

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" );

// This example uses the SHA1 algorithm.
// Due to collision problems with SHA1, Microsoft recommends SHA256 or better.
string sha1Oid = CryptoConfig.MapNameToOID("SHA1");

' (OID) from the string name of the SHA1 algorithm.
' This example uses the SHA1 algorithm.
' Due to collision problems with SHA1, Microsoft recommends SHA256 or better.
Dim sha1Oid As String = cryptoConfig.MapNameToOID("SHA1")
