Hello Rohit,
We use Amazonica to read files from a bucket encrypted with Server-Side
Encryption (SSE).
The way to do it depends on the way the files were encrypted. If the KMS
key was "associated" with the encrypted file (not sure if I'm using the
correct terminology, I'm no AWS expert) and the instance/role has IAM
permission for that KMS key, it should be enough to add :encryption true to
the parameters map:
(require '[amazonica.aws.s3 :as s3])
(s3/get-object {:bucket-name "mybucket", :key "/foo/bar", :encryption true}
If you need to set the KMS key explicitly, what worked for us is adding
:sse-aws-key-management-params
{:aws-kms-key-id "<encryption key name here>"} to the same parameters map.
Try this out, if it doesn't work I'll try to understand how our code works
a little better. But ultimately we'll make it work for you;).
