Object Storage - Encryption/Decryption of files stored and File access link

Content

Hi,

We have an immediate requirement where file uploads to the object storage needs to be encrypted. And downloads from the object storage should be decrypted. 

Is there an inherent option within object storage to achieve it? We will be using object storage to store files having critical content. 

And also, want to know if there is a direct file access link that can be used to download the file (if one has read access to the particular object storage bucket)?

Any pointers will be appreciated.
