      Summary of necessary driver changes

      • Use libmongocrypt containing changes for MONGOCRYPT-614. MONGOCRYPT-614 is available in libmongocrypt 1.10.0. Binaries are available in this Evergreen upload-all task to test.
      • Document the new "delegated" option for the KMIP masterKey in ClientEncryption::createDataKey.
      • C driver required no other changes.

      Commits for syncing spec/prose tests
      (and/or refer to an existing language POC if needed)

      • Spec tests were added in 57b77d8 and amended in dc6eb4c

      Summary

      Previous versions of the KMIP spec did not support encrypt and decrypt functionality.  It was added in 1.2 but even those using 1.2 didn't necessarily support the encrypt/decrypt calls.  For CSFLE and Queryable Encryption, that means that the CMK is what needs to be transported back and forth from the key provider to the driver, which is less than ideal from a security standpoint because you are exposing a wrapping key.  If that wrapping key is exposed all dek encrypted with it can be decrypted.  HashiCorp Vault Enterprise added support for encrypt/decrypt in their 1.13 version, at our request, so that we can use KMIP like we do for the other key providers, which is sending the cleartext DEK to the key provider for encryption and sending encrypted DEK for decryption.
