Create S3 access credentials

Every time you access the S3 API, you will need a key pair consisting of an Access Key and a Secret Key. This guide shows you how to generate it in centron Cloud-Panel.

Prerequisites

• An active centron account with Object Storage subscribed
• Access to the Cloud-Panel

Step by step

1. Log in to centron Cloud-Panel.
2. Switch to ccenter – you can do this by clicking on the dotted square on the top toolbar, next to the news bell.
3. Next, open the S3 Users overview under S3 Storage.
4. Now click Edit next to the desired user account.
5. In the overview that opens, you can generate new S3 access credentials on the left by clicking Generate Access Key.
6. Copy the Secret Key immediately from the banner that appears and store it in a secure place (e.g. a password manager).

Secret Key is only displayed once

Once the dialogue box has been closed, the secret key cannot be viewed again. If it is lost, a new key pair must be generated.

Best practices

• One key pair per system: This allows a compromised key to be blocked in a targeted manner.
• No keys in the code: Access credentials belong in environment variables, secret managers or configuration files with restrictive permissions – never in Git repositories.
• Regular rotation: Generate new keys at appropriate intervals and delete the old ones.
• Delete keys that are no longer needed: Every active key is a potential vulnerability.

Delete key pair

1. Open Object Storage → Access Credentials.
2. Select Delete for the relevant key and confirm.

Access using this pair will be blocked immediately; any stored data will be retained.
