      Returns:
      the identifier for the created data key

    • encrypt

      BsonBinary encrypt(BsonValue value, EncryptOptions options)
      Encrypt the given value with the given options.

      The driver may throw an exception for prohibited BSON value types

      Parameters:
      value - the value to encrypt
      options - the options for data encryption
      Returns:
      the encrypted value, a BSON binary of subtype 6

    • encryptExpression

      @Beta(SERVER) BsonDocument encryptExpression(Bson expression, EncryptOptions options)
      Encrypts a Match Expression or Aggregate Expression to query a range index.

      The expression is expected to be in one of the following forms:

      • A Match Expression of this form: {$and: [{<field>: {$gt: <value1>}}, {<field>: {$lt: <value2> }}]}
      • An Aggregate Expression of this form: {$and: [{$gt: [<fieldpath>, <value1>]}, {$lt: [<fieldpath>, <value2>]}] }
      $gt may also be $gte. $lt may also be $lte.

      Only supported when queryType is "rangePreview" and algorithm is "RangePreview".

      Note: The Range algorithm is experimental only. It is not intended for public use. It is subject to breaking changes.

      Parameters:
      expression - the Match Expression or Aggregate Expression
      options - the options
      Returns:
      the encrypted queryable range expression

    • createEncryptedCollection

      BsonDocument createEncryptedCollection(MongoDatabase database, String collectionName, CreateCollectionOptions createCollectionOptions, CreateEncryptedCollectionParams createEncryptedCollectionParams)
      Create a new collection with encrypted fields, automatically creating new data encryption keys when needed based on the configured encryptedFields, which must be specified. This method does not modify the configured encryptedFields when creating new data keys, instead it creates a new configuration if needed.
      Parameters:
      database - The database to use for creating the collection.
      collectionName - The name for the collection to create.
      createCollectionOptions - Options for creating the collection.
      createEncryptedCollectionParams - Auxiliary parameters for creating an encrypted collection.
      Returns:
      The (potentially updated) encryptedFields configuration that was used to create the collection. A user may use this document to configure AutoEncryptionSettings.getEncryptedFieldsMap().
      Throws:
      MongoUpdatedEncryptedFieldsException - If an exception happens after creating at least one data key. This exception makes the updated encryptedFields available to the caller.
