- A failed verification of received sales tariff (in ChargeParameterDiscoveryRes) does not lead any more to the termination of the communication session, but to just ignoring the sales tariff so that the charge process itself can still continue.
- Additional check if TLS is used when selecting a payment option from the offered list of payment options. If the SECC is offering a contract-based payment although no TLS is used (in this case the SECC shall not offer contract-based payment after all), the EVCC will not select 'CONTRACT' any more but 'EIM' instead.
- The received private key of the contract certificate (upon receipt of CertificateInstallationRes/CertificateUpdateRes) is first checked according to [V2G2-823] before saving the private key. If the check fails, the contract certificate and private key will not be safed (BUT: check is not complete, additional help with ECC mechanisms might be needed).
- All other files: Just the slight modification of the copyright header (which has been done in the master branch, but not the developer branch)
- shortend all IDs of reference signature headers to 3 characters like the example given in Annex J (because some embedded systems might restrict the length to 3 characters)
- SecurityUtils: minor additional checks in verifySignature() method
- avoided NullPointerException when incoming message does not have ISO 15118 schema (for example DINSPEC 70121 XSD schema for DC charging)
- made sure optional parameters of ServiceDiscoveryRes are not empty when sent
- added logging message which shows which payment option was chosen by EVCC
- added optional parameter EVSEIsolationStatus in DCEVSEStatus as some EVCC systems tend to need this value according to testival
- bug fix: applied correct private key for signing sales tariff (must be MOSub2CA private key)
- made sure EVCC does not choose contract based payment if SECC offers it although no TLS communication is set up
- Corrected the verification process of received (signed) sales tariffs (EVCC side)
- changed default value for XMLRepresentationOfMessages to false (SECC side)
- caching result of getContractCertificateStatus() in communication session object to further reduce cryptographic computation overhead
- added another property to file EVCCConfig.properties and SECCConfig.properties called 'XMLRepresentationOfMessages' to allow to easily switch between verbose debugging (showing XML representation of sent messages) and less verbose logging information
- added ResponseCode 'OK_CertificateExpiresSoon' on SECC side when receiving ContractCertificate with PaymentDetailsReq
- modified TLSClient to initiate TLS handshake right when initializing TLSClient (instead of when sending first message), thus enabling the check for the correct domain component "CPO" of the SECC certificate
- validates now provisioning certificate chain and checks for correct domain component "CPS" of provisioning leaf certificate
- added SecurityUtils function to get contract certificate from EVCC keystore
- added SecurityUtils function to get validity period of contract certificate
- added SecurityUtils function to also check for correct domain component when checking validity of certificate
- implemented a correct check if certificate update or installation is needed upon receiving PaymentServiceSelectionRes on EVCC side
