| Nossa biblioteca de criptografia do lado do cliente foi renomeada para SDK de criptografia de AWS banco de dados. Este guia do desenvolvedor ainda fornece informações sobre o [DynamoDB Encryption Client](legacy-dynamodb-encryption-client.md). | 

Os exemplos a seguir demonstram como configurar beacons padrão e compostos. As configurações a seguir não fornecem comprimentos de beacon. Para obter ajuda na determinação do comprimento adequado do beacon para sua configuração, consulte [Escolher um comprimento do beacon](choosing-beacon-length.md).

Para ver exemplos completos de código que demonstram como configurar e usar beacons, consulte os exemplos de criptografia pesquisável em [Java](https://github.com/aws/aws-database-encryption-sdk-dynamodb//tree/main/Examples/runtimes/java/DynamoDbEncryption/src/main/java/software/amazon/cryptography/examples/searchableencryption), [.NET](https://github.com/aws/aws-database-encryption-sdk-dynamodb/tree/main/Examples/runtimes/net/src/searchableencryption/) e [Rust](https://github.com/aws/aws-database-encryption-sdk-dynamodb/blob/main/releases/rust/db_esdk/examples/searchableencryption/) no repositório -dynamodb em. aws-database-encryption-sdk GitHub

## Beacons padrão
<a name="standard-config-examples"></a>

Se você quiser consultar o campo `inspector_id_last4` para obter correspondências exatas, crie um beacon padrão usando a configuração a seguir.

------
#### [ Java ]

```
List<StandardBeacon> standardBeaconList = new ArrayList<>();
StandardBeacon exampleStandardBeacon = StandardBeacon.builder()
    .name("inspector_id_last4")
    .length(beaconLengthInBits)
    .build();
standardBeaconList.add(exampleStandardBeacon);
```

------
#### [ C\$1 / .NET ]

```
var standardBeaconList = new List<StandardBeacon>>);
StandardBeacon exampleStandardBeacon = new StandardBeacon
  {
    Name = "inspector_id_last4",
    Length = 10
  };
standardBeaconList.Add(exampleStandardBeacon);
```

------
#### [ Rust ]

```
let last4_beacon = StandardBeacon::builder()
    .name("inspector_id_last4")
    .length(10)
    .build()?;
                        
let unit_beacon = StandardBeacon::builder().name("unit").length(30).build()?;

let standard_beacon_list = vec![last4_beacon, unit_beacon];
```

------

## Beacons compostos
<a name="compound-config-examples"></a>

Se você quiser consultar o banco de dados `UnitInspection` em `inspector_id_last4` e `inspector_id_last4.unit`, crie um beacon composto com a configuração a seguir. Este beacon composto requer apenas [partes criptografadas](configure-beacons.md#encrypted-parts).

------
#### [ Java ]

```
// 1. Create standard beacons for the inspector_id_last4 and unit fields.
List<StandardBeacon> standardBeaconList = new ArrayList<>();
StandardBeacon inspectorBeacon = StandardBeacon.builder()
    .name("inspector_id_last4")
    .length(beaconLengthInBits)
    .build();
standardBeaconList.add(inspectorBeacon);

StandardBeacon unitBeacon = StandardBeacon.builder()
    .name("unit")
    .length(beaconLengthInBits)
    .build();
standardBeaconList.add(unitBeacon);        

// 2. Define the encrypted parts.
List<EncryptedPart> encryptedPartList = new ArrayList<>();

// Each encrypted part needs a name and prefix
// The name must be the name of the standard beacon
// The prefix must be unique
// For this example we use the prefix "I-" for "inspector_id_last4"
// and "U-" for "unit"
EncryptedPart encryptedPartInspector = EncryptedPart.builder()
    .name("inspector_id_last4")
    .prefix("I-")
    .build();
encryptedPartList.add(encryptedPartInspector);

EncryptedPart encryptedPartUnit = EncryptedPart.builder()
    .name("unit")
    .prefix("U-")
    .build();
encryptedPartList.add(encryptedPartUnit);   

// 3. Create the compound beacon.
// This compound beacon only requires a name, split character, 
// and list of encrypted parts
CompoundBeacon inspectorUnitBeacon = CompoundBeacon.builder()
    .name("inspectorUnitBeacon")
    .split(".")
    .sensitive(encryptedPartList)
    .build();
```

#### [ C\$1 / .NET ]

```
// 1. Create standard beacons for the inspector_id_last4 and unit fields.
StandardBeacon inspectorBeacon = new StandardBeacon
 {
   Name = "inspector_id_last4",
   Length = 10
 };
standardBeaconList.Add(inspectorBeacon);
StandardBeacon unitBeacon = new StandardBeacon
 {
    Name = "unit",
    Length = 30
 };  
standardBeaconList.Add(unitBeacon);
                
// 2. Define the encrypted parts.
var last4EncryptedPart = new EncryptedPart

// Each encrypted part needs a name and prefix
// The name must be the name of the standard beacon
// The prefix must be unique
// For this example we use the prefix "I-" for "inspector_id_last4"
// and "U-" for "unit"
var last4EncryptedPart = new EncryptedPart
 {
   Name = "inspector_id_last4",
   Prefix = "I-"
 };
encryptedPartList.Add(last4EncryptedPart);

var unitEncryptedPart = new EncryptedPart
 {
   Name = "unit",
   Prefix = "U-"
 };
encryptedPartList.Add(unitEncryptedPart); 

// 3. Create the compound beacon.
// This compound beacon only requires a name, split character, 
// and list of encrypted parts
var compoundBeaconList = new List<CompoundBeacon>>);
var inspectorCompoundBeacon = new CompoundBeacon
  {
      Name = "inspector_id_last4",
      Split = ".",
      Encrypted = encryptedPartList
  };
compoundBeaconList.Add(inspectorCompoundBeacon);
```
