CertOIDToAlgId function

Use the CryptFindOIDInfo function instead of this function because ALG_ID identifiers are no longer supported in CNG. Use the CRYPT_OID_INFO_OID_KEY value in the dwKeyType parameter of the CryptFindOIDInfo function instead.

Windows Server 2003 and Windows XP:  

The CertOIDToAlgId function converts the Abstract Syntax Notation One (ASN.1) object identifier (OID) string to the CryptoAPI algorithm identifier (ALG_ID).

Syntax

DWORD WINAPI CertOIDToAlgId(
  _In_ LPCSTR pszObjId
);

Parameters

pszObjId [in]

Pointer to the ASN.1 OID to be converted to an algorithm identifier.

Return value

Returns the ALG_ID that corresponds to the object identifier (OID) or zero if no ALG_ID corresponds to the OID.

Examples

See Example C Program: Using CertOIDToAlgId and CertCompareIntegerBlob.
