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.
