These Win32® functions provide Object Identifier (OID) support. You can use these functions to install, register, and dispatch to OID and encoding type-specific functions. The APIs that make use of these functions are CryptEncodeObject, CryptEncodeObjectEx, CryptDecodeObject, CryptDecodeObjectEx, CertVerifyRevocation, and CertOpenStore. For an overview of this process, see Extending CryptoAPI Functionality
The following functions are included in this category and can also be found in Wincrypt.h.
| Function | Description |
|---|---|
| CryptEnumOIDFunction | Enumerates the OID functions identified by their encoding type, function name, and OID. |
| CryptEnumOIDInfo | Enumerates the OID Information identified by their group and calls pfnEnumOIDInfo for matches. |
| CryptFindOIDInfo | Uses the specified key and group to find OID information. |
| CryptFreeOIDFunctionAddress | Releases the handle count that was incremented and returned by CryptGetOIDFunctionAddress or CryptGetDefaultOIDFunctionAddress. |
| CryptGetDefaultOIDDllList | Gets the list of registered default Dll entries for the specified function set and encoding type. |
| CryptGetDefaultOIDFunctionAddress | Either gets the first or next installed DEFAULT function or loads the Dll containing the DEFAULT function. |
| CryptGetOIDFunctionAddress | Searches the list of installed functions for an encoding type and OID match. If a match isn't found there, then the registry is searched for a match. |
| CryptGetOIDFunctionValue | Gets the value for the specified encoding type, function name, OID, and value name. |
| CryptInitOIDFunctionSet | Initializes and returns a handle to the OID function set identified by the function name supplied. |
| CryptInstallOIDFunctionAddress | Installs a set of callable OID function addresses. |
| CryptRegisterDefaultOIDFunction | Registers the Dll containing the default function to be called for the specified encoding type and function name. |
| CryptRegisterOIDFunction | Registers the Dll containing the function to be called for the specified encoding type, function name, and OID. |
| CryptRegisterOIDInfo | Registers the OID information specified in the CRYPT_OID_INFO structure, persisting it to the registry. |
| CryptSetOIDFunctionValue | Sets the value for the specified encoding type, function name, OID, and value name. |
| CryptUnregisterDefaultOIDFunction | Removes the registration for the Dll containing the default function to be called for the specified encoding type and function name. |
| CryptUnregisterOIDFunction | Removes the registration for the Dll containing the function to be called for the specified encoding type, function name, and OID. |
| CryptUnregisterOIDInfo | Removes the registration for the specified OID information. |
