proof_req_json: &str,
requested_credentials_json: &str,
master_secret_id: &str,
schemas_json: &str,
credential_defs_json: &str,

) -> Box<dyn Future<Item = String, Error = IndyError>>
Creates a proof according to the given proof request Either a corresponding credential with optionally revealed attributes or self-attested attribute must be provided for each requested attribute (see indy_prover_get_credentials_for_pool_req). A proof request may request multiple credentials from different schemas and different issuers. All required schemas, public keys and revocation registries must be provided. The proof request also contains nonce. The proof contains either proof or self-attested attribute value for each requested attribute.

Returns
proof_json- proof json For each requested attribute either a proof (with optionally revealed attribute value) or self-attested attribute value is provided. Each proof is associated with a credential and corresponding schema_id, cred_def_id, rev_reg_id and timestamp. There is also aggregated proof part common for all credential proofs. { "requested_proof": { "revealed_attrs": { "requested_attr1_id": {sub_proof_index: number, raw: string, encoded: string}, "requested_attr4_id": {sub_proof_index: number: string, encoded: string}, }, "unrevealed_attrs": { "requested_attr3_id": {sub_proof_index: number} }, "self_attested_attrs": { "requested_attr2_id": self_attested_value, }, "requested_predicates": { "requested_predicate_1_referent": {sub_proof_index: int}, "requested_predicate_2_referent": {sub_proof_index: int}, } } "proof": { "proofs": [ <credential_proof>, <credential_proof>, <credential_proof> ], "aggregated_proof": <aggregated_proof> } "identifiers": [{schema_id, cred_def_id, Optional<rev_reg_id>, Optional}] }
