The central object for DRM interaction.

Typedef Documentation

◆ SHI_Engine

typedef struct SHI_Engine SHI_Engine

A SHI_Engine object is the initial point of interaction between an application and a DRM Engine.

It encapsulates the state of a DRM Engine, provides access to internal data structures, and provides information about transactions that it is performing on behalf of the application.

Function Documentation

◆ SHI_Engine_Create()

SHI_PUBLIC_API SHI_Result SHI_Engine_Create ( const SHI_EngineConfig config,
SHI_Engine **  engine 
)

Creates a SHI_Engine object.

This object must be destroyed by calling SHI_Engine_Destroy when it is no longer needed.

The configuration passed to this method specifies configuration flags and the listener that will receive the event callbacks.

Parameters
configPointer to the configuration for the engine.
engineAddress of a SHI_Engine pointer that will be set to refer to the SHI_Engine object created.

Creates a new SHI_License object managed by this engine.

That is, the SHI_License object is local to this engine, and cannot be used independently of it. The SHI_License object must be destroyed by calling SHI_License_Destroy when it is no longer needed, prior to destroying the engine.

Parameters
selfThe SHI_Engine that will manage the license.
licenseAddress of a SHI_License pointer that will be set to refer to the SHI_License created.

object_idThe ID of the Octopus object.

◆ SHI_Engine_Destroy()

SHI_PUBLIC_API SHI_Result SHI_Engine_Destroy ( SHI_Engine self)

The returned certificates are in DER (Distinguished Encoding Rules) encoded format starting with the leaf certificate to the trust anchor.

Parameters
selfA SHI_Engine pointer.
cert_chainThe type of certificate chain to be fetched.
cert_arrayAddress of a SHI_Data pointer that will be set to point to a SHI_Data object representing an array of certificates. This SHI_Data object will be of type SHI_DATA_TYPE_ARRAY, where each element in the array will be of type SHI_DATA_TYPE_BYTE_ARRAY, and its value is a SHI_ByteArray. Each SHI_ByteArray structure contains the DER encoded certificate data and its size in bytes.

◆ SHI_Engine_IsPersonalized()

SHI_PUBLIC_API SHI_Boolean SHI_Engine_IsPersonalized ( SHI_Engine self)

Indicates whether or not this engine has been personalized.

Parameters

◆ SHI_Engine_Personalize()

SHI_PUBLIC_API SHI_Result SHI_Engine_Personalize ( SHI_Engine self,
const char *  token,
SHI_Size  token_size,
const void *  cookie 
)

Requests that this engine engage in the personalization process.

This method performs the personalization synchronously and does not return until it is complete. The progress and results are signaled by callbacks to the engine's event listener. Note: The personalization process is represented by a transaction of SHI_TransactionType SHI_TRANSACTION_TYPE_PERSONALIZATION.

The 'token' parameter can be NULL in which case the token_size is ignored, and a default personalization token is utilized. Such a default personalization token can be selected at build time through the Sushi Configuration procedure. See the Sushi Deployment Guide for details.

The return value for this method indicates simply whether the method call succeeded. The success or failure result of the transaction for performing personalization is specified in the final callback indicating the end of the transaction.

See SHI_EngineConfig for pseudo code of a proper listener that captures any transaction failure.

If this engine is already personalized, this method returns SHI_ERROR_ENGINE_ALREADY_PERSONALIZED.

Parameters
selfThe SHI_Engine to be personalized.
tokenPointer to the service token data, or NULL.
token_sizeSize in bytes of the service token data.
cookieAn arbitrary pointer that will be passed back to the engine listener in callbacks regarding any transaction related to the processing of the personalization.

◆ SHI_Engine_ProcessServiceToken()

SHI_PUBLIC_API SHI_Result SHI_Engine_ProcessServiceToken ( SHI_Engine self,
const char *  token,
SHI_Size  token_size,
const void *  cookie 
)

Requests that this engine process a service token, such as a Broadband Action Token.

This method performs all operations synchronously and does not return until completing processing of the service token. The progress and status information are signaled by callbacks to the engine's event listener.

The return value for this method indicates simply whether the method call succeeded. The success or failure result of the transaction for processing the service token is specified in the final callback indicating the end of the transaction.

See SHI_EngineConfig for pseudo code of a proper listener that captures any transaction failure.

Parameters
selfThe SHI_Engine that will process the token.
tokenPointer to the service token data.
token_sizeSize in bytes of the service token data.
cookieAn arbitrary pointer that will be passed back to the engine listener in callbacks regarding any transaction related to the processing of this token.

const char *  token,
SHI_Size  token_size,
const void *  cookie,
SHI_RegistrationDataManager registration_data_manager

Requests that this engine process a service token, such as a Broadband Action Token.

This method performs all operations synchronously and does not return until completing processing of the service token. The progress and status information are signaled by callbacks to the engine's event listener.

The return value for this method indicates simply whether the method call succeeded. The success or failure result of the transaction for processing the service token is specified in the final callback indicating the end of the transaction.

See SHI_EngineConfig for pseudo code of a proper listener that captures any transaction failure.

Transforms a URI template according to the "URI Templates for Marlin" specification.

Parameters
selfA SHI_Engine pointer.
uri_templateThe URI template, containing zero or more placeholder substrings to be replaced.
uriAddress of a SHI_Data pointer that will be set to refer to a SHI_Data string object containing the result of transforming the URI template.

◆ SHI_Engine_UpdatePersonality()

SHI_PUBLIC_API SHI_Result SHI_Engine_UpdatePersonality ( SHI_Engine self,
const char *  token,
SHI_Size  token_size,
const void *  cookie 
)

Requests that this engine engage in the personality update process to renew its public credentials.

This method performs the personality update synchronously and does not return until it is complete. The progress and results are signaled by callbacks to the engine's event listener. Note: The personality update process is represented by a transaction of SHI_TransactionType SHI_TRANSACTION_TYPE_PERSONALITY_UPDATE.

The return value for this method indicates simply whether the method call succeeded. The success or failure result of the transaction for performing personalization is specified in the final callback indicating the end of the transaction.

See SHI_EngineConfig for pseudo code of a proper listener that captures any transaction failure.

If this engine is not personalized, this method returns SHI_ERROR_ENGINE_NOT_PERSONALIZED.

Parameters
selfThe SHI_Engine to be personalized.
tokenPointer to the service token data.
token_sizeSize in bytes of the service token data.
cookieAn arbitrary pointer that will be passed back to the engine listener in callbacks regarding any transaction related to the processing of the update personality.

)

Updates security data for a specified service configured for this engine object.

The return value for this method indicates simply whether the method call succeeded. The success or failure result of the underlying transaction is specified in the final callback indicating the end of the transaction.

See SHI_EngineConfig for pseudo code of a proper listener that captures any transaction failure.

Parameters
selfThe SHI_Engine for which a service will be updated.
service_idID of the service whose security data will be updated.
last_updateIf an update has occurred within the last last_update seconds, the security data will not be updated when the function is called. Callers can pass zero to mean update regardless of when the last update occurred.
cookieAn arbitrary pointer that will be passed back to the engine listener in callbacks regarding any transaction related to the processing of this update.

SHI_PUBLIC_API SHI_Result SHI_Engine_VacuumData ( SHI_Engine self,
SHI_Flags  vacuum_options 
)

Removes expired data stored in Sushi's database.

After this method is called, this engine instance may not be used again. You must destroy this engine and create a new instance. Engine methods may return SHI_ERROR_ENGINE_POST_VACUUM after this call. Note: the engine must be destroyed even if SHI_Engine_VacuumData returns an error code.

Parameters
selfA SHI_Engine pointer.
vacuum_optionsThe type of data to be vacuumed (permanently deleted), as specified in SHI_ENGINE_VACUUM_FLAG_XXX flags.
