'What's the best approach to verify integrity for crypted files on AWS EFS?

Hello i'm working for the first time with AWS EFS, and for security reasons in my organization data will be stored encrypted, but not with AWS standard EFS encryption.

For each upload request, encryption keys are collected via a VPN, encrypt the binary and than store file on EFS.

Each upload part must not exceed 200MB, and all parts must be merged at the end of the upload.

I'm looking for the best approach to make things a litle bit easy in a complicated architecture, so what's the best approach to verify integriry ?:

  1. Uploaded file is as same as received on server side
  2. Loaded EFS file is as same as stored

Thanks.
