[−][src]Function indyrs::anoncreds::prover_get_credentials_for_proof_req

pub fn prover_get_credentials_for_proof_req(
    wallet_handle: WalletHandle, 
    proof_request_json: &str
) -> Box<dyn Future<Item = String, Error = IndyError>>

Gets human readable credentials matching the given proof request.

NOTE: This method is deprecated because immediately returns all fetched credentials. Use <search_credentials_for_proof_req> to fetch records by small batches.

Arguments

  • wallet_handle: wallet handle (created by Wallet::open_wallet).
  • proof_request_json: proof request json { "name": string, "version": string, "nonce": string, - a big number represented as a string (use generate_nonce function to generate 80-bit number) "requested_attributes": { // set of requested attributes "<attr_referent>": <attr_info>, // see below ..., }, "requested_predicates": { // set of requested predicates "<predicate_referent>": <predicate_info>, // see below ..., }, "non_revoked": Optional<<non_revoc_interval>>, // see below, // If specified prover must proof non-revocation // for date in this interval for each attribute // (can be overridden on attribute level) }

where attr_referent: Proof-request local identifier of requested attribute attr_info: Describes requested attribute { "name": string, // attribute name, (case insensitive and ignore spaces) "restrictions": Optional<filter_json>, // see above "non_revoked": Optional<<non_revoc_interval>>, // see below, // If specified prover must proof non-revocation // for date in this interval this attribute // (overrides proof level interval) } predicate_referent: Proof-request local identifier of requested attribute predicate predicate_info: Describes requested attribute predicate { "name": attribute name, (case insensitive and ignore spaces) "p_type": predicate type (Currently ">=" only) "p_value": int predicate value "restrictions": Optional<filter_json>, // see above "non_revoked": Optional<<non_revoc_interval>>, // see below, // If specified prover must proof non-revocation // for date in this interval this attribute // (overrides proof level interval) } non_revoc_interval: Defines non-revocation interval { "from": Optional, // timestamp of interval beginning "to": Optional, // timestamp of interval ending }

Returns

  • credentials_json: json with credentials for the given proof request. { "requested_attrs": { "<attr_referent>": [{ cred_info: <credential_info>, interval: Optional<non_revoc_interval> }], ..., }, "requested_predicates": { "requested_predicates": [{ cred_info: <credential_info>, timestamp: Optional }, { cred_info: <credential_2_info>, timestamp: Optional }], "requested_predicate_2_referent": [{ cred_info: <credential_2_info>, timestamp: Optional }] } }, where credential is { "referent": , "attrs": {"attr_name" : "attr_raw_value"}, "schema_id": string, "cred_def_id": string, "rev_reg_id": Optional, "cred_rev_id": Optional, }
