CSFLE - Integration with more KMS providers like Hashicorp Vault
Automatic CSFLE - To generate and manage the Customer Master key, can we add more KMS providers like Hashicorp Vault. KMS providers currently supported are only: Amazon Web Services KMS and Locally Managed Keyfile.
To work with Hashicorp Vault, it seems, we need to choose Locally Managed Keyfile as the KMS provider. This means that the Master key will be fetched from Vault in memory and then used in the code to encrypt/decrypt the DEK (Data Encryption Key). Ideally, the decryption of DEK should happen in the vault itself as a best practice, and master key should not be brought out of Vault.
Using only AWS KMS is a limitation. Using Locally Managed Keyfile to read key from
another KMS and then use in application is not secure.
Can more KMS providers be supported in a more secure way?
Thanks

Hi all,
With the release of server 5.0 this coming July, we will also GA our integration with Azure and GCP as KMS providers. Hashicorp Vault is planned for later in 2021, along with generic or custom built key management solution support.
