MONGOC_CLIENT...UTO_ENCRYPTION(3)

🦋 mongoc_client_pool_enable_auto_encryption — libmongoc, bestie 💅

okay so this is a page from libmongoc and it's about turning on automatic client-side encryption for a whole client pool. Very main-character function. Let's get into it ✨

✨ SYNOPSIS ✨

bool
mongoc_client_pool_enable_auto_encryption (mongoc_client_pool_t *pool,
                                           mongoc_auto_encryption_opts_t* opts,
                                           bson_error_t* error);

---

💖 DESCRIPTION 💖

So literally what this does is enable automatic client side encryption on a mongoc_client_pool_t. Slay. 🎀

But heads up: this requires libmongoc to be built with support for In-Use Encryption. Check out the In-Use Encryption docs for the instructions on how to enable In-Use Encryption in libmongoc — no cap, you can't skip that step. 🫶

Automatic encryption is an enterprise-only feature, and it only applies to operations on a collection. It is not supported for operations on a database or view, and operations that aren't bypassed will result in error. 💀 So if you wanna bypass automatic encryption for all operations, do it with mongoc_auto_encryption_opts_set_bypass_auto_encryption() in opts.

Also, automatic encryption requires the authenticated user to have the listCollections privilege action. iykyk 🔑

And ngl, enabling automatic encryption reduces the maximum message size and may have a negative performance impact. Worth knowing before you turn it on, fr fr. 🦋
