oe_get_evidence

Generates the evidence for the given format id. This function is only available in the enclave.

This feature is marked as experimental:
Parameters
[in]format_idThe format ID of the evidence to be generated.
[in]flagsA bit-wise parameter. Currently there is one bit defined: OE_EVIDENCE_FLAGS_EMBED_FORMAT_ID. If this bit is set, the evidence and endorsements will be wrapped with a header containing the format ID.
[in]custom_claims_bufferThe optional custom claims buffer.
[in]custom_claims_buffer_sizeThe number of bytes in the custom claims buffer.
[in]optional_parametersThe optional format-specific input parameters.
[in]optional_parameters_sizeThe size of optional_parameters in bytes.
[out]evidence_bufferAn output pointer that will be assigned the address of the dynamically allocated evidence buffer.
[out]evidence_buffer_sizeA pointer that points to the size of the evidence buffer in bytes.
[out]endorsements_bufferIf not NULL, an output pointer that will be assigned the address of the dynamically allocated endorsements buffer.
[out]endorsements_buffer_sizeA pointer that points to the size of the endorsements buffer in bytes.
Return values
OE_OKThe function succeeded.
OE_INVALID_PARAMETERAt least one of the parameters is invalid.
OE_NOT_FOUNDThe input evidence format id is not supported.
