    • encrypt

      Publisher<BsonBinary> encrypt(BsonValue value, EncryptOptions options)

    • encryptExpression

      Publisher<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 "range" and algorithm is "Range".

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

    • createEncryptedCollection

      Publisher<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:
      A publisher of the (potentially updated) encryptedFields configuration that was used to create the collection. A user may use this document to configure AutoEncryptionSettings.getEncryptedFieldsMap().

      Signals MongoUpdatedEncryptedFieldsException if an exception happens after creating at least one data key. This exception makes the updated encryptedFields available to the caller.
