encryption/decryption between backend and s3proxy

[nonix]

Hi guys,
I am new to this S3proxy. And would appreciate your help. I am looking for ability to encrypt / decrypt payload on the way to/from backend.
The task:

• My client send PUT request to store the payload to S3 (compatible) backend as un-encrypted.
• The S3Proxy should "intercept" and encrypt the payload with a pre-configured keys ideal using AES 256-CBC
• Than store the encrypted payload on S3 backend
• Analogues on the way back.

Is this possible to achieve with this S3Proxy?

Thank you,
N.

S3Proxy has an EncryptedBlobStore middleware. However this is not currently discoverable: #398 (comment)

It would be great if either @nonix or @FlorinPeter could add a wiki page for this.
