Hi,

Can we use Vault for data encryption at rest for databases like Posrgres? I mean, we want the data to be encrypted on the disk and Vault to act as a proxy to provide encryption and decryption capabilities the way it is provided by Amazon RDS (Relational Database Service) using AWS KMS. I went through Vault Transit documentation but its not very clear to me at this stage. 

Thanks,
Rakesh

Hi Rakesh,

You can certainly do it with Transit, but you'd have to encrypt/decrypt outside the confines of the database -- for instance, using a proxy layer that you send queries to and first roundtrips data to/from Vault. I think there has been some interest in the postgres community for a plugin that will do this automatically for you but I don't think such a postgres plugin exists right now.

If you're interested in using Vault for database encryption, do take a look at convergent encryption as it allows you to search within the encrypted data.

Best,
Jeff

Thanks Jeff. I will try Vault Transit and update community if it works out for us.
