Hi all,

I'm sure my question was already answered but I didn't find anything here ...

I'm using s3 output and what I do not understand is the encrypting part...

I specify `server_side_encryption = true`, `server_side_encryption_algorithm => "AES256"`

everything works but when i use `s3cmd get` to see how the file looks like is not crypted at all...

If i do `aws:kms` and `ssekms_key_id => "my_key"` the result is still the same, I get the files clearly not crypted...

Am i missing something? and Where should i specify the key for AES256?

thanks
