Class JsonObjectCrypto

java.lang.Object
com.couchbase.client.java.json.JsonObjectCrypto
@Volatile
public class JsonObjectCrypto
extends Object
A view of a Couchbase JsonObject for reading and writing encrypted fields.

The methods of this class mirror the methods of JsonObject, and behave the same way except they operate on encrypted values. Values read via the crypto object are decrypted, and values written via the view are encrypted.

The JsonObjectCrypto view can only see encrypted fields. Attempting to read an unencrypted field via the view has the same result as if the field does not exist.

New instances are created by calling JsonObject.crypto(com.couchbase.client.core.encryption.CryptoManager).

Example usage: 

 Collection collection = cluster.bucket("myBucket").defaultCollection();

 JsonObject document = JsonObject.create();
 JsonObjectCrypto crypto = document.crypto(collection);
 crypto.put("locationOfBuriedTreasure", "Between palm trees");

 // This displays the encrypted form of the field
 System.out.println(document);

 collection.upsert("treasureMap", document);

 JsonObject readItBack = collection.get("treasureMap").contentAsObject();
 JsonObjectCrypto readItBackCrypto = readItBack.crypto(collection);
 System.out.println(readItBackCrypto.getString("locationOfBuriedTreasure"));

  • Method Details

    • withEncrypter

      public JsonObjectCrypto withEncrypter​(String encrypterAlias)
      Returns a new JsonObjectCrypto instance that uses the decrypter identified by the given alias.

    • withDefaultEncrypter

      public JsonObjectCrypto withDefaultEncrypter()
      Returns a new JsonObjectCrypto instance that uses the default encrypter.
