#initialize(mongocrypt, io, doc, options = {}) ⇒ ExplicitEncryptionContext

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Note:

The RangePreview algorithm is experimental only. It is not intended for

Create a new ExplicitEncryptionContext object

public use.

Parameters:

  • mongocrypt (Mongo::Crypt::Handle) —

    a Handle that wraps a mongocrypt_t object used to create a new mongocrypt_ctx_t

  • io (ClientEncryption::IO) —

    A instance of the IO class that implements driver I/O methods required to run the state machine

  • doc (BSON::Document) —

    A document to encrypt

  • options (Hash) (defaults to: {})

Options Hash (options):

  • :key_id (BSON::Binary) —

    A BSON::Binary object of type :uuid representing the UUID of the data key to use for encryption.

  • :key_alt_name (String) —

    The alternate name of the data key that will be used to encrypt the value.

  • :algorithm (String) —

    The algorithm used to encrypt the value. Valid algorithms are “AEAD_AES_256_CBC_HMAC_SHA_512-Deterministic”, “AEAD_AES_256_CBC_HMAC_SHA_512-Random”, “Indexed”, “Unindexed”, “RangePreview”.

  • :contention_factor (Integer | nil) —

    Contention factor to be applied if encryption algorithm is set to “Indexed”. If not provided, it defaults to a value of 0. Contention factor should be set only if encryption algorithm is set to “Indexed”.

  • query_type (String | nil) —

    Query type to be applied if encryption algorithm is set to “Indexed” or “RangePreview”. Allowed values are “equality” and “rangePreview”.

  • :range_opts (Hash | nil) —

    Specifies index options for a Queryable Encryption field supporting “rangePreview” queries. Allowed options are:

    • :min

    • :max

    • :sparsity

    • :precision

    min, max, sparsity, and range must match the values set in the encryptedFields of the destination collection. For double and decimal128, min/max/precision must all be set, or all be unset.
