One-Call function for TPM2_Quote
This function invokes the TPM2_Quote 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
-
[in,out] | esysContext | The ESYS_CONTEXT. |
[in] | signHandle | Handle of key that will perform signature. |
[in] | shandle1 | Session handle for authorization of signHandle |
[in] | shandle2 | Second session handle. |
[in] | shandle3 | Third session handle. |
[in] | qualifyingData | Data supplied by the caller. |
[in] | inScheme | TPM2_Signing scheme to use if the scheme for signHandle is TPM2_ALG_NULL. |
[in] | PCRselect | PCR set to quote. |
[out] | quoted | The quoted information. (callee-allocated) |
[out] | signature | The signature over quoted . (callee-allocated) |
- 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_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. |

Asynchronous function for TPM2_Quote
This function invokes the TPM2_Quote 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_Quote_Finish.
- Parameters
-
[in,out] | esysContext | The ESYS_CONTEXT. |
[in] | signHandle | Handle of key that will perform signature. |
[in] | shandle1 | Session handle for authorization of signHandle |
[in] | shandle2 | Second session handle. |
[in] | shandle3 | Third session handle. |
[in] | qualifyingData | Data supplied by the caller. |
[in] | inScheme | TPM2_Signing scheme to use if the scheme for signHandle is TPM2_ALG_NULL. |
[in] | PCRselect | PCR set to quote. |
- 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_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. |

Asynchronous finish function for TPM2_Quote
This function returns the results of a TPM2_Quote command invoked via Esys_Quote_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
-
[in,out] | esysContext | The ESYS_CONTEXT. |
[out] | quoted | The quoted information. (callee-allocated) |
[out] | signature | The signature over quoted . (callee-allocated) |
- 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. |
