NAME

Fapi_CreateKey - Fapi_CreateKey

SYNOPSIS

Functions


TSS2_RC Fapi_CreateKey (FAPI_CONTEXT *context, char const *path, char const *type, char const *policyPath, char const *authValue)
TSS2_RC Fapi_CreateKey_Async (FAPI_CONTEXT *context, char const *path, char const *type, char const *policyPath, char const *authValue)
TSS2_RC Fapi_CreateKey_Finish (FAPI_CONTEXT *context)

Detailed Description

FAPI functions to invoke CreateKey either as one-call or in an asynchronous manner.

Function Documentation

Fapi_CreateKey (FAPI_CONTEXT * context, char const * path, char const * type, char const * policyPath, char const * authValue)

One-Call function for Fapi_CreateKey

Creates a key inside the TPM based on the Key type, using the supplied policy and authValue. The key is then stored either in the FAPI metadata store or the TPM.

Parameters

context The FAPI_CONTEXT
path The path where the new key is stored
type The type of the new key. May be NULL
policyPath The path to the policy that is associated with the new key. May be NULL
authValue The authorization value for the new key. May be NULL

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context or path is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_BAD_PATH if policyPath is non-NULL and does not map to a FAPI policy.
TSS2_FAPI_RC_KEY_NOT_FOUND if the parent key does not map to a FAPI key.
TSS2_FAPI_RC_PATH_ALREADY_EXISTS if a file already exists at path.
TSS2_FAPI_RC_BAD_VALUE if the keyType is non-NULL and invalid.
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_TRY_AGAIN if an I/O operation is not finished yet and this function needs to be called again.
TSS2_FAPI_RC_AUTHORIZATION_UNKNOWN if a required authorization callback is not set.
TSS2_ESYS_RC_* possible error codes of ESAPI.
TSS2_FAPI_RC_PATH_NOT_FOUND if a FAPI object path was not found during authorization.
TSS2_FAPI_RC_GENERAL_FAILURE if an internal error occured.
TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned.
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.

Fapi_CreateKey_Async (FAPI_CONTEXT * context, char const * path, char const * type, char const * policyPath, char const * authValue)

Asynchronous function for Fapi_CreateKey

Creates a key inside the TPM based on the Key type, using the supplied policy and authValue. The key is then stored either in the FAPI metadata store or the TPM.

Call Fapi_CreateKey_Finish to finish the execution of this command.

Parameters

context The FAPI_CONTEXT
path The path where the new key is stored
type The type of the new key. May be NULL
policyPath The path to the policy that is associated with the new key. May be NULL
authValue The authorization value for the new key. May be NULL

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context or path is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_BAD_PATH if policyPath is non-NULL and does not map to a FAPI policy.
TSS2_FAPI_RC_KEY_NOT_FOUND if the parent key does not map to a FAPI key.
TSS2_FAPI_RC_PATH_ALREADY_EXISTS if a file already exists at path.
TSS2_FAPI_RC_BAD_VALUE if the keyType is non-NULL and invalid.
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.

Fapi_CreateKey_Finish (FAPI_CONTEXT * context)

Asynchronous finish function for Fapi_CreateKey

This function should be called after a previous Fapi_CreateKey_Async.

Parameters

context The FAPI_CONTEXT

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context 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_VALUE if an invalid value was passed into the function.
TSS2_FAPI_RC_AUTHORIZATION_UNKNOWN if a required authorization callback is not set.
TSS2_ESYS_RC_* possible error codes of ESAPI.
TSS2_FAPI_RC_GENERAL_FAILURE if an internal error occured.
TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned.
TSS2_FAPI_RC_KEY_NOT_FOUND if a key was not found.
TSS2_FAPI_RC_BAD_PATH if the path is used in inappropriate context or contains illegal characters.
TSS2_FAPI_RC_PATH_NOT_FOUND if a FAPI object path was not found during authorization.
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_FAPI_RC_PATH_ALREADY_EXISTS if the object already exists in object store.
