Azure Confidential Ledger client library samples for Java

Azure Confidential Ledger samples are a set of self-contained Java programs that demonstrate interacting with Azure self-contained service using the client library. Each sample focuses on a specific scenario and can be executed independently.

Key concepts

Key concepts are explained in detail here.

Examples

ConfidentialLedgerCertificateClientBuilder confidentialLedgerCertificateClientbuilder = new ConfidentialLedgerCertificateClientBuilder()
    .certificateEndpoint("https://identity.confidential-ledger.core.azure.com")
    .credential(new DefaultAzureCredentialBuilder().build())
    .httpClient(HttpClient.createDefault());
        
ConfidentialLedgerCertificateClient confidentialLedgerCertificateClient = confidentialLedgerCertificateClientbuilder.buildClient();

String ledgerId = "java-tests";
Response<BinaryData> ledgerCertificateWithResponse = confidentialLedgerCertificateClient
    .getLedgerIdentityWithResponse(ledgerId, null);
BinaryData certificateResponse = ledgerCertificateWithResponse.getValue();
ObjectMapper mapper = new ObjectMapper();
JsonNode jsonNode = mapper.readTree(certificateResponse.toBytes());
String ledgerTlsCertificate = jsonNode.get("ledgerTlsCertificate").asText();


SslContext sslContext = SslContextBuilder.forClient()
    .trustManager(new ByteArrayInputStream(ledgerTlsCertificate.getBytes(StandardCharsets.UTF_8))).build();
reactor.netty.http.client.HttpClient reactorClient = reactor.netty.http.client.HttpClient.create()
    .secure(sslContextSpec -> sslContextSpec.sslContext(sslContext));
HttpClient httpClient = new NettyAsyncHttpClientBuilder(reactorClient).wiretap(true).build();

ConfidentialLedgerClient confidentialLedgerClient =
    new ConfidentialLedgerClientBuilder()
            .credential(new DefaultAzureCredentialBuilder().build())
            .httpClient(httpClient)
            .ledgerEndpoint("https://my-ledger.confidential-ledger.azure.com")
            .buildClient();

The following sections provide code samples covering common scenario operations with the Azure Confidential Ledger client library.

All of these samples need the endpoint to your Confidential Ledger resource, and your Confidential Ledger API key.

File Name	Description
ConfidentialLedgerClientSample.java	Sample code to configure your client base with
CreateOrUpdateUserSample.java	Add a user to a ledger or update an existing user
DeleteUserSample.java	Delete a user from a ledger
ListCollectionIdsSample.java	Get a list of all collection ids for a ledger
ListConsortiumMembersSample.java	Get all consortium members for a ledger
GetConstitutionSample.java	Get the constitution for a ledger
GetCurrentLedgerEntrySample.java	Get the most recent ledger entry
GetEnclaveQuotesSample.java	Get the enclave quotes for a ledger
GetLedgerEntriesSample.java	List ledger entries in the confidential ledger
GetLedgerEntrySample.java	Get a specific ledger entry
GetLedgerIdentitySample.java	Get the identity of a ledger
GetReceiptSample.java	Get a receipt from a transaction
GetTransactionStatusSample.java	Get the status of a ledger entry
GetUserSample.java	Get specific user data from a ledger
PostLedgerEntrySample.java	Add a ledger entry. This also contains a more robust example of response handling.
