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 CertOIDToAlgId(
[in] LPCSTR pszObjId
);
Parameters
[in] pszObjId
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.
