Configurazioni di esempio

La nostra libreria di crittografia lato client è stata rinominata Database Encryption SDK. AWS Questa guida per sviluppatori fornisce ancora informazioni sul DynamoDB Encryption Client.

Gli esempi seguenti mostrano come configurare beacon standard e composti. Le seguenti configurazioni non forniscono le lunghezze dei beacon. Per informazioni sulla determinazione della lunghezza del beacon appropriata per la configurazione, consulta Scelta della lunghezza del beacon.

Per vedere esempi di codice completi che dimostrano come configurare e utilizzare i beacon, consulta gli esempi di crittografia ricercabile in Java, .NET e Rust nel repository -dynamodb on. aws-database-encryption-sdk GitHub

Beacon standard

Se desideri interrogare il inspector_id_last4 campo per verificare le corrispondenze esatte, crea un beacon standard utilizzando la seguente configurazione.

Java
List<StandardBeacon> standardBeaconList = new ArrayList<>();
StandardBeacon exampleStandardBeacon = StandardBeacon.builder()
    .name("inspector_id_last4")
    .length(beaconLengthInBits)
    .build();
standardBeaconList.add(exampleStandardBeacon);
C# / .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];

Fari composti

Se vuoi interrogare il UnitInspection database su inspector_id_last4 andinspector_id_last4.unit, crea un beacon composto con la seguente configurazione. Questo beacon composto richiede solo parti criptate.

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# / .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);
Rust
// 1. Create standard beacons for the inspector_id_last4 and unit fields.
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];
                        
// 2. Define the encrypted parts.
// 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"
let encrypted_parts_list = vec![
    EncryptedPart::builder()
        .name("inspector_id_last4")
        .prefix("I-")
        .build()?,
    EncryptedPart::builder().name("unit").prefix("U-").build()?,
];

// 3. Create the compound beacon
// This compound beacon only requires a name, split character, 
// and list of encrypted parts
let compound_beacon_list = vec![CompoundBeacon::builder()
    .name("last4UnitCompound")
    .split(".")
    .encrypted(encrypted_parts_list)
    .build()?];
