The file needs to be decrypted when synced back down to the serverĮlevate your permissions to root: sudo su.This file needs to be encrypted with a custom key.You need to upload a file to the user's private download directory on S3.This section covers the following scenario: Uploading SSE-C encrypted files to a private download directory You cannot move nor copy objects encrypted with SSE-C.At the bottom of the object detail page, you will see an error: Error: an unexpected error occurred.On the object detail page, you will not see anything under Server side encryption.When using SSE-C, the S3 console will behave strangely.

(This is just an example, please use a real key) You will need a Base64 Encoded AES-256 Key, which looks something like this: fS9LLRGAy8twrmcPSjhT9d0IhWPq4mhY93dFD5uaMEs= But it is up to you to thoroughly test your workflow and safeguard against data loss. The following sections are suggestions on using When using SSE-C, you are responsible for managingĮncryption keys, and for tracking which key was used for each object. Note: It's recommended to use SSE-S3 or KMS whenever possible. SSE-C is more difficult to manage, and there's a risk of data loss if you misplace your key. However, only do this if you have a specific compliance You can provide your own key for server-side encryption.
