Functions


TSS2_RC Fapi_VerifyQuote (FAPI_CONTEXT *context, char const *publicKeyPath, uint8_t const *qualifyingData, size_t qualifyingDataSize, char const *quoteInfo, uint8_t const *signature, size_t signatureSize, char const *pcrLog)
TSS2_RC Fapi_VerifyQuote_Async (FAPI_CONTEXT *context, char const *publicKeyPath, uint8_t const *qualifyingData, size_t qualifyingDataSize, char const *quoteInfo, uint8_t const *signature, size_t signatureSize, char const *pcrLog)
TSS2_RC Fapi_VerifyQuote_Finish (FAPI_CONTEXT *context)

Detailed Description

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

Function Documentation

TSS2_RC Fapi_VerifyQuote (FAPI_CONTEXT * context, char const * publicKeyPath, uint8_t const * qualifyingData, size_t qualifyingDataSize, char const * quoteInfo, uint8_t const * signature, size_t signatureSize, char const * pcrLog)

One-Call function for Fapi_VerifyQuote

Verifies that the data returned by a quote is valid.

Parameters

context The FAPI_CONTEXT
publicKeyPath The path to the signing key
qualifyingData The qualifying data nonce. May be NULL
qualifyingDataSize The size of qualifyingData in bytes. Must be 0 if qualifyingData is NULL
quoteInfo The quote information
signature The quote's signature
signatureSize The size of signature in bytes
pcrLog The PCR's log. May be NULL

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context, publicKeyPath, quoteInfo, or signature is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_KEY_NOT_FOUND if path does not map to a FAPI entity.
TSS2_FAPI_RC_BAD_KEY if the entity at path is not a key, or is a key that is unsuitable for the requested operation.
TSS2_FAPI_RC_BAD_VALUE if quoteInfo, pcrEventLog, qualifyingData, or signature is 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_PATH_NOT_FOUND if a FAPI object path was not found during authorization.
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_SIGNATURE_VERIFICATION_FAILED if the signature could not be verified
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.

TSS2_RC Fapi_VerifyQuote_Async (FAPI_CONTEXT * context, char const * publicKeyPath, uint8_t const * qualifyingData, size_t qualifyingDataSize, char const * quoteInfo, uint8_t const * signature, size_t signatureSize, char const * pcrLog)

Asynchronous function for Fapi_VerifyQuote

Verifies that the data returned by a quote is valid. Call Fapi_VerifyQuote_Finish to finish the execution of this command.

Parameters

context The FAPI_CONTEXT
publicKeyPath The path to the signing key
qualifyingData The qualifying data nonce. May be NULL
qualifyingDataSize The size of qualifyingData in bytes. Must be 0 if qualifyingData is NULL
quoteInfo The quote information
signature The quote's signature
signatureSize The size of signature in bytes
pcrLog The PCR's log. May be NULL

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context, publicKeyPath, quoteInfo, or signature is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_KEY_NOT_FOUND if path does not map to a FAPI entity.
TSS2_FAPI_RC_BAD_KEY if the entity at path is not a key, or is a key that is unsuitable for the requested operation.
TSS2_FAPI_RC_BAD_VALUE if quoteInfo, pcrEventLog, qualifyingData, or signature is 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_PATH_NOT_FOUND if a FAPI object path was not found during authorization.
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.

TSS2_RC Fapi_VerifyQuote_Finish (FAPI_CONTEXT * context)

Asynchronous finish function for Fapi_VerifyQuote

This function should be called after a previous Fapi_VerifyQuote_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_GENERAL_FAILURE if an internal error occurred.
TSS2_FAPI_RC_SIGNATURE_VERIFICATION_FAILED if the signature could not be verified
