Usage Examples

// Initialize Conjur client
ConjurConfigManager.ConjurConfiguration config = new ConjurConfigManager.ConjurConfiguration(
"https://conjur.example.com", "my-account")
.withUsername("admin@my-account")
.withApiKey("your-api-key")
.withCertFile("/etc/conjur/conjur.pem");
ConjurClient conjurClient = new ConjurClient(config);
// Create secrets management service
SecretsManagementService secretsService = new SecretsManagementService(conjurClient);
// Retrieve secrets
String dbPassword = secretsService.getSecret("myapp/database/password");
DatabaseConfig dbConfig = secretsService.getDatabaseConfig("myapp/database");
// Use in application
DataSource dataSource = DataSourceBuilder.create()
.url(dbConfig.getConnectionString())
.username(dbConfig.getUsername())
.password(dbConfig.getPassword())
.build();
