Example of usage
Create a Denm-message and encode it to an ETSI compliant uPer encoded message with geonet security header
using Digitraffic.link.facilities;
using Digitraffic.link.transport;
String key = "<your_key>";
//Optional: Add a logger to SDK
ConsoleLogger logger = new ConsoleLogger(Level.Info);
//If needed initialize software security module
SoftwareSecurityModule ssm = new SoftwareSecurityModule("<password>", "<path to persistant store>", logger);
//Initiate PKI handling for signing and verification of messages
ETSISecurity_L0 sec = new ETSISecurity_L0("<signingCertificateID>", ssm, false, logger);
//Initialize library (pass null for argument log to disable logging)
LibInitializer.Initialize(key, log, sec);
//Initialize clients (pass null for argument log to disable logging)
ConnectInitializer.Initialize(key, log);
/* Create a new EtsiMessage with geonetheader according to ETSI TS 103 097 */
EtsiMessage message = new EtsiMessage(CompileFlags.Signed);
/* Create a new payload of the type DENM211 (Decentralized Notication Message version 2.1.1) */
DENM211 payload = new DENM211();
/* Add the payload to the EtsiMessage */
message.Payload = payload;
/* Generate the complete Etsi binary message signed with Iee1609 credential */
byte[] binaryEtsiMessage = message.Encode();
