The official programming language drivers for MongoDB 4.2 now support client-side field-level encryption. The implications for security improvements are enormous. This enhancement means that your applications can now provide end-to-end encryption for transmitted data down to the field level. So you could have a transmission of data from your application to MongoDB that includes, for example, an encrypted national identification number mixed in with otherwise plain-text data.
You can refer to https://docs.mongodb.com/master/core/security-client-side-encryption/#driver-compatibility-table to access the drivers for MongoDB 4.2. For client-side field-level encryption, you can refer to https://docs.mongodb.com/master/core/security-client-side-encryption/#client-side-field-level-encryption.
