Java library to convert and send Swift Messages to NEM Blockchain and vice versa
Set up your Node first via app.properties.
The library uses the Builder Pattern to create and send transactions.
Create a app.properties file on your classpath and add the following:node.endpoint.networkname=testnet
node.endpoint.protocol=http
node.endpoint.uri=<testnet node>
node.endpoint.port=7890// swift message
final String sampleSwiftMsg = "{1:F21FOOLHKH0AXXX0304009999}{4:{177:1608140809}{451:0}}{1:F01FOOLHKH0AXXX0304009999}{2:O9401609160814FOOLHKH0AXXX03040027341608141609N}{4:\n"

// set the account
final Account senderAccount = EntityFactory.buildAccountFromPrivateKey("<privatekey>");
final Account recipientAccount = EntityFactory.buildAccountFromPublicKey("<publickey>");
// prepare the payload message.
SecureMessage message = SecureMessageSwiftPayloadEncoder.encodeAndGzipCompress(senderAccount, recipientAccount, sampleSwiftMsg);
// use the builder to build and send the transaction.
SwiftTransactionBuilder

// set the account
final Account senderAccount = EntityFactory.buildAccountFromPrivateKey("<privatekey>");
final Account recipientAccount = EntityFactory.buildAccountFromPublicKey("<publickey>");
// Get the decoded message.
String decodedPayload = SecureMessageSwiftPayloadDecoder.decodeAndGzipUncompress(senderKeyPair, recipientKeyPairPriv,encryptedMessage);
Documentation to follow.
Run the JUnit Test cases using Maven or use it as a reference.
mvn test
To test the funtionality with real data, set the sender, recipient and multisig via the super class TransactionUnitTest class.
@Before // for encoding.
public void init() {
this.setAccountMultisigAccountPublicKey(...);
this.setAccountSenderPrivateKey(...);
this.setAccountRecipientPublicKey(...);
}
@Before // for decoding.
public void init() {
this.setAccountMultisigAccountPublicKey(...);
this.setAccountSenderPublicKey(...);
this.setAccountRecipientPrivateKey(...);
}Like any other maven project, just do the maven command below.
mvn clean install
