Function Documentation

Fapi_ExportKey (FAPI_CONTEXT * context, char const * pathOfKeyToDuplicate, char const * pathToPublicKeyOfNewParent, char ** exportedData)

One-Call function for Fapi_ExportKey

Given a key it will (if the key is a storage key) duplicate the key and package up the duplicated key and all keys below it into a file ready to move to a new TPM.

Parameters

context The FAPI_CONTEXT
pathOfKeyToDuplicate The path to the root of the subtree to export.
pathToPublicKeyOfNewParent The path to the public key of the new parent. May be NULL
exportedData The exported subtree

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context, pathOfKeyToDuplicate or exportedData is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_KEY_NOT_FOUND if pathOfKeyToDuplicate or pathToPublicKeyOfNewParent does not map to a . FAPI object.
TSS2_FAPI_RC_BAD_KEY if the key at pathToPublicKeyOfNewParent is not suitable for the requeste operation.
TSS2_FAPI_RC_KEY_NOT_DUPLICABLE if the key is not a duplicable key.
TSS2_FAPI_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending.
TSS2_FAPI_RC_IO_ERROR if the data cannot be saved.
TSS2_FAPI_RC_MEMORY if the FAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_FAPI_RC_NO_TPM if FAPI was initialized in no-TPM-mode via its config file.
TSS2_FAPI_RC_PATH_NOT_FOUND if a FAPI object path was not found during authorization.
TSS2_FAPI_RC_BAD_VALUE if an invalid value was passed into the function.
TSS2_FAPI_RC_BAD_PATH if a path is used in inappropriate context or contains illegal characters.
TSS2_FAPI_RC_TRY_AGAIN if an I/O operation is not finished yet and this function needs to be called again.
TSS2_FAPI_RC_GENERAL_FAILURE if an internal error occurred.
TSS2_FAPI_RC_AUTHORIZATION_UNKNOWN if a required authorization callback is not set.
TSS2_FAPI_RC_AUTHORIZATION_FAILED if the authorization attempt fails.
TSS2_FAPI_RC_POLICY_UNKNOWN if policy search for a certain policy digest was not successful.
TSS2_ESYS_RC_* possible error codes of ESAPI.
TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned.

Fapi_ExportKey_Async (FAPI_CONTEXT * context, char const * pathOfKeyToDuplicate, char const * pathToPublicKeyOfNewParent)

Asynchronous function for Fapi_ExportKey

Given a key it will (if the key is a storage key) duplicate the key and package up the duplicated key and all keys below it into a file ready to move to a new TPM.

Call Fapi_ExportKey_Finish to finish the execution of this command.

Parameters

context The FAPI_CONTEXT
pathOfKeyToDuplicate The path to the root of the subtree to export.
pathToPublicKeyOfNewParent The path to the public key of the new parent

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context or pathOfKeyToDuplicate is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_KEY_NOT_FOUND if pathOfKeyToDuplicate or pathToPublicKeyOfNewParent does not map to a . FAPI object.
TSS2_FAPI_RC_BAD_KEY if the key at pathToPublicKeyOfNewParent is not suitable for the requeste operation.
TSS2_FAPI_RC_KEY_NOT_DUPLICABLE if the key is not a duplicable key.
TSS2_FAPI_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending.
TSS2_FAPI_RC_IO_ERROR if the data cannot be saved.
TSS2_FAPI_RC_MEMORY if the FAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_FAPI_RC_NO_TPM if FAPI was initialized in no-TPM-mode via its config file.
TSS2_FAPI_RC_PATH_NOT_FOUND if a FAPI object path was not found during authorization.
TSS2_FAPI_RC_BAD_VALUE if an invalid value was passed into the function.
TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned.
TSS2_FAPI_RC_BAD_PATH if the path is used in inappropriate context or contains illegal characters.

Fapi_ExportKey_Finish (FAPI_CONTEXT * context, char ** exportedData)

Asynchronous finish function for Fapi_ExportKey

This function should be called after a previous Fapi_ExportKey_Async.

Parameters

context The FAPI_CONTEXT
exportedData The exported subtree

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context or exportedData is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending.
TSS2_FAPI_RC_IO_ERROR if the data cannot be saved.
TSS2_FAPI_RC_MEMORY if the FAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_FAPI_RC_TRY_AGAIN if the asynchronous operation is not yet complete. Call this function again later.
TSS2_FAPI_RC_BAD_PATH if a path is used in inappropriate context or contains illegal characters.
TSS2_FAPI_RC_BAD_VALUE if an invalid value was passed into the function.
TSS2_FAPI_RC_GENERAL_FAILURE if an internal error occurred.
TSS2_FAPI_RC_PATH_NOT_FOUND if a FAPI object path was not found during authorization.
TSS2_FAPI_RC_KEY_NOT_FOUND if a key was not found.
TSS2_FAPI_RC_AUTHORIZATION_UNKNOWN if a required authorization callback is not set.
TSS2_FAPI_RC_AUTHORIZATION_FAILED if the authorization attempt fails.
TSS2_FAPI_RC_POLICY_UNKNOWN if policy search for a certain policy digest was not successful.
