Esys_HashSequenceStart - The ESAPI function for the
TPM2_HashSequenceStart command.
TSS2_RC Esys_HashSequenceStart_Async (ESYS_CONTEXT
*esysContext, ESYS_TR shandle1, ESYS_TR shandle2,
ESYS_TR shandle3, const TPM2B_AUTH *auth, TPMI_ALG_HASH hashAlg)
TSS2_RC Esys_HashSequenceStart (ESYS_CONTEXT *esysContext,
ESYS_TR shandle1, ESYS_TR shandle2, ESYS_TR shandle3,
const TPM2B_AUTH *auth, TPMI_ALG_HASH hashAlg, ESYS_TR
*sequenceHandle)
TSS2_RC Esys_HashSequenceStart_Finish (ESYS_CONTEXT
*esysContext, ESYS_TR *sequenceHandle)
ESAPI function to invoke the TPM2_HashSequenceStart command either
as a one-call or in an asynchronous manner.
One-Call function for TPM2_HashSequenceStart
This function invokes the TPM2_HashSequenceStart command in a
one-call variant. This means the function will block until the TPM response
is available. All input parameters are const. The memory for non-simple
output parameters is allocated by the function implementation.
Parameters
esysContext The ESYS_CONTEXT.
shandle1 First session handle.
shandle2 Second session handle.
shandle3 Third session handle.
auth Authorization value for subsequent use of the sequence.
hashAlg The hash algorithm to use for the hash sequence.
sequenceHandle ESYS_TR handle of ESYS resource for TPMI_DH_OBJECT.
Return values
TSS2_RC_SUCCESS if the function call was a
success.
TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers
or required output handle references are NULL.
TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for
internal operations or return parameters.
TSS2_ESYS_RC_BAD_SEQUENCE if the context has an asynchronous operation
already pending.
TSS2_ESYS_RC_INSUFFICIENT_RESPONSE if the TPM's response does not at
least contain the tag, response length, and response code.
TSS2_ESYS_RC_MALFORMED_RESPONSE if the TPM's response is corrupted.
TSS2_ESYS_RC_RSP_AUTH_FAILED if the response HMAC from the TPM did not
verify.
TSS2_ESYS_RC_MULTIPLE_DECRYPT_SESSIONS if more than one session has the
'decrypt' attribute bit set.
TSS2_ESYS_RC_MULTIPLE_ENCRYPT_SESSIONS if more than one session has the
'encrypt' attribute bit set.
TSS2_ESYS_RC_NO_ENCRYPT_PARAM if one of the sessions has the 'encrypt'
attribute set and the command does not support encryption of the first
response parameter.
TSS2_RCs produced by lower layers of the software stack may be returned
to the caller unaltered unless handled internally.
Asynchronous function for TPM2_HashSequenceStart
This function invokes the TPM2_HashSequenceStart command in a
asynchronous variant. This means the function will return as soon as the
command has been sent downwards the stack to the TPM. All input parameters
are const. In order to retrieve the TPM's response call
Esys_HashSequenceStart_Finish.
Parameters
esysContext The ESYS_CONTEXT.
shandle1 First session handle.
shandle2 Second session handle.
shandle3 Third session handle.
auth Authorization value for subsequent use of the sequence.
hashAlg The hash algorithm to use for the hash sequence.
Return values
ESYS_RC_SUCCESS if the function call was a
success.
TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers
or required output handle references are NULL.
TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for
internal operations or return parameters.
TSS2_RCs produced by lower layers of the software stack may be returned
to the caller unaltered unless handled internally.
TSS2_ESYS_RC_MULTIPLE_DECRYPT_SESSIONS if more than one session has the
'decrypt' attribute bit set.
TSS2_ESYS_RC_MULTIPLE_ENCRYPT_SESSIONS if more than one session has the
'encrypt' attribute bit set.
TSS2_ESYS_RC_NO_ENCRYPT_PARAM if one of the sessions has the 'encrypt'
attribute set and the command does not support encryption of the first
response parameter.
Asynchronous finish function for TPM2_HashSequenceStart
This function returns the results of a TPM2_HashSequenceStart
command invoked via Esys_HashSequenceStart_Finish. All non-simple output
parameters are allocated by the function's implementation. NULL can be
passed for every output parameter if the value is not required.
Parameters
esysContext The ESYS_CONTEXT.
sequenceHandle ESYS_TR handle of ESYS resource for TPMI_DH_OBJECT.
Return values
TSS2_RC_SUCCESS on success
ESYS_RC_SUCCESS if the function call was a success.
TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers
or required output handle references are NULL.
TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for
internal operations or return parameters.
TSS2_ESYS_RC_BAD_SEQUENCE if the context has an asynchronous operation
already pending.
TSS2_ESYS_RC_TRY_AGAIN if the timeout counter expires before the TPM
response is received.
TSS2_ESYS_RC_INSUFFICIENT_RESPONSE if the TPM's response does not at
least contain the tag, response length, and response code.
TSS2_ESYS_RC_RSP_AUTH_FAILED if the response HMAC from the TPM did not
verify.
TSS2_ESYS_RC_MALFORMED_RESPONSE if the TPM's response is corrupted.
TSS2_RCs produced by lower layers of the software stack may be returned
to the caller unaltered unless handled internally.
