Detailed Description¶
ESAPI function to invoke the TPM2_GetSessionAuditDigest command either as a one-call or in an asynchronous manner.
Function Documentation¶

One-Call function for TPM2_GetSessionAuditDigest
This function invokes the TPM2_GetSessionAuditDigest 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
privacyAdminHandle TPM2_Handle of the privacy administrator (TPM2_RH_ENDORSEMENT).
signHandle Handle of the signing key.
sessionHandle Handle of the audit session.
shandle1 Session handle for authorization of privacyAdminHandle
shandle2 Session handle for authorization of signHandle
shandle3 Third session handle.
qualifyingData User-provided qualifying data - may be zero-length.
inScheme TPM2_Signing scheme to use if the scheme for signHandle is TPM2_ALG_NULL.
auditInfo The audit information that was signed. (callee-allocated)
signature The signature over auditInfo. (callee-allocated)
Return values
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_BAD_TR if any of the ESYS_TR objects are unknown to the ESYS_CONTEXT or are of the wrong type or if required ESYS_TR objects are ESYS_TR_NONE.
TSS2_RCs produced by lower layers of the software stack may be returned to the caller unaltered unless handled internally.
TSS2_RC Esys_GetSessionAuditDigest_Async (ESYS_CONTEXT * esysContext, ESYS_TR privacyAdminHandle, ESYS_TR signHandle, ESYS_TR sessionHandle, ESYS_TR shandle1, ESYS_TR shandle2, ESYS_TR shandle3, const TPM2B_DATA * qualifyingData, const TPMT_SIG_SCHEME * inScheme)¶
Asynchronous function for TPM2_GetSessionAuditDigest
This function invokes the TPM2_GetSessionAuditDigest 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_GetSessionAuditDigest_Finish.
Parameters
privacyAdminHandle TPM2_Handle of the privacy administrator (TPM2_RH_ENDORSEMENT).
signHandle Handle of the signing key.
sessionHandle Handle of the audit session.
shandle1 Session handle for authorization of privacyAdminHandle
shandle2 Session handle for authorization of signHandle
shandle3 Third session handle.
qualifyingData User-provided qualifying data - may be zero-length.
inScheme TPM2_Signing scheme to use if the scheme for signHandle is TPM2_ALG_NULL.
Return values
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_BAD_TR if any of the ESYS_TR objects are unknown to the ESYS_CONTEXT or are of the wrong type or if required ESYS_TR objects are ESYS_TR_NONE.
TSS2_RC Esys_GetSessionAuditDigest_Finish (ESYS_CONTEXT * esysContext, TPM2B_ATTEST ** auditInfo, TPMT_SIGNATURE ** signature)¶
Asynchronous finish function for TPM2_GetSessionAuditDigest
This function returns the results of a TPM2_GetSessionAuditDigest command invoked via Esys_GetSessionAuditDigest_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
auditInfo The audit information that was signed. (callee-allocated)
signature The signature over auditInfo. (callee-allocated)
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_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.
