NAME

       Esys_Hash - The ESAPI function for the TPM2_Hash command.

SYNOPSIS

   Functions
       TSS2_RC Esys_Hash_Finish (ESYS_CONTEXT *esysContext, TPM2B_DIGEST **outHash,
           TPMT_TK_HASHCHECK **validation)

Detailed Description

       ESAPI function to invoke the TPM2_Hash command either as a one-call or in an asynchronous
       manner.

Function Documentation

   TSS2_RC Esys_Hash_Finish (ESYS_CONTEXT * esysContext, TPM2B_DIGEST ** outHash,
       TPMT_TK_HASHCHECK ** validation)
       Asynchronous finish function for TPM2_Hash

       This function returns the results of a TPM2_Hash command invoked via Esys_Hash_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.
           outHash Results. (callee-allocated)
           validation TPM2_Ticket indicating that the sequence of octets used to compute
           outDigest did not start with TPM2_GENERATED_VALUE. (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.
           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.
