+# Object Storange And Data Encryption
+
+## Object Storage
+
+By default, demarches-simplifiees.fr uses an [OVH Object Storage](https://www.ovhcloud.com/en/public-cloud/object-storage/) backend. The hard-drives are encrypted at rest, but to protect user files even better, demarches-simplifiees.fr can also use an external encryption proxy, that will encrypt and decrypt files on the fly:
+
+* Encryption is done via our [proxy](https://github.com/betagouv/ds_proxy) when the file is uploaded by a client.
+* Decryption is done via the same proxy when the file is downloaded to a client
+
+### Object Storage limitation
+
+As an s3 compatible object storage backend, OVH Object Storage suffers the same limitations.
+
+One of them being that when you upload a file bigger than 5Go, it must be chunked into segments (see the [documentation](https://docs.ovh.com/fr/storage/pcs/capabilities-and-limitations/#max_file_size-5368709122-5gb)).
+
+This process to chunks the file in segment, then re-arrange it via a manifest. Unfortunately encryption can't work with this usecase.
+
+So we are using a custom script that wraps two call to our proxy in order to buffer all the chunks, encrypt/decrypt the whole. Here is an example
+
+```
+#!/usr/bin/env bash
+# wrapper script to encrypt and upload file received from archive
+
+set -o errexit
+set -o pipefail
+set -o nounset
+
+# params
+# 1: filename
+# 2: key
+if ! [ "$#" -eq 2 ]; then
+    echo "usage: $0 <filename> <key>"
+    exit 1
+fi
+local_file_path=$1
+remote_basename=$(basename $local_file_path)
+key=$2
+
+# encrypt
+curl -s -XPUT http://ds_proxy_host:ds_proxy_port/local/encrypt/${remote_basename} --data-binary @${local_file_path}
+
+# get back encrypted file
+encrypted_filename="${local_file_path}.enc"
+curl -s http://ds_proxy_host:ds_proxy_port/local/encrypt/${remote_basename} -o ${encrypted_filename}
+
+# OVH openstack params
+os_tenant_name=os_tenant_name
+os_username=os_username
+os_password=os_password
+os_region_name=GRA
+
+# auth = https://auth.cloud.ovh.net/v3/
+# use haproxy proxy and not direct internet URL
+os_auth_url="os_auth_url"
+os_storage_url="os_storage_url" \
+container_name=container_name
+
+expiring_delay="$((60 * 60 * 24 * 4))" # 4 days
+
+# upload
+/usr/local/bin/swift \
+  --auth-version 3 \
+  --os-auth-url "$os_auth_url" \
+  --os-storage-url "$os_storage_url" \
+  --os-region-name "$os_region_name" \
+  --os-tenant-name "$os_tenant_name" \
+  --os-username "$os_username" \
+  --os-password "$os_password" \
+  upload \
+  --header "X-Delete-After: ${expiring_delay}" \
+  --segment-size "$((3 * 1024 * 1024 * 1024))" \
+  --header "Content-Disposition: filename=${remote_basename}" \
+  --object-name "${key}" \
+  "${container_name}" "${encrypted_filename}"
+
+swift_exit_code=$?
+
+# cleanup
+rm ${encrypted_filename}
