The MongoDB\Driver\ClientEncryption class

Intro

The MongoDB\Driver\ClientEncryption class handles creation of data keys for client-side encryption, as well as manually encrypting and decrypting values.

Class synopsis

Predefined Constants

MongoDB\Driver\ClientEncryption::AEAD_AES_256_CBC_HMAC_SHA_512_DETERMINISTIC

Specifies an algorithm for deterministic encryption, which is suitable for querying.

MongoDB\Driver\ClientEncryption::AEAD_AES_256_CBC_HMAC_SHA_512_RANDOM

Specifies an algorithm for randomized encryption

MongoDB\Driver\ClientEncryption::ALGORITHM_INDEXED

Specifies an algorithm for an indexed, encrypted payload, which can be used with queryable encryption.

To insert or query with an indexed, encrypted payload, the MongoDB\Driver\Manager must be configured with the "autoEncryption" driver option. The "bypassQueryAnalysis" auto encryption option may be true. The "bypassAutoEncryption" auto encryption option must be false.

MongoDB\Driver\ClientEncryption::ALGORITHM_UNINDEXED

Specifies an algorithm for an unindexed, encrypted payload.

MongoDB\Driver\ClientEncryption::ALGORITHM_RANGE

Specifies an algorithm for a range encrypted payload, which can be used with queryable encryption.

To query with a range encrypted payload, the MongoDB\Driver\Manager must be configured with the "autoEncryption" driver option. The "bypassQueryAnalysis" auto encryption option may be true. The "bypassAutoEncryption" auto encryption option must be false.

Note

The extension does not yet support range queries for Decimal128 BSON field types.

MongoDB\Driver\ClientEncryption::QUERY_TYPE_EQUALITY

Specifies an equality query type, which is used in conjunction with MongoDB\Driver\ClientEncryption::ALGORITHM_INDEXED.

MongoDB\Driver\ClientEncryption::QUERY_TYPE_RANGE

Specifies a range query type, which is used in conjunction with MongoDB\Driver\ClientEncryption::ALGORITHM_RANGE.
