Rotate Sidecar Authentication Keys

ALTR supports two public keys to enable uninterrupted key rotation. Once an old key is no longer in use, it can be safely deleted.

Keys can be rotated to improve security posture and meet compliance requirements.

To rotate sidecar authentication keys:

  1. Generate a new RSA key pair.

  2. Save the new public key in ALTR.

    1. Log into ALTR via Okta.

    2. Select Settings → Sidecars in the Navigation menu.

    3. Click the sidecar to view details. Under Public Keys, there are two key fields.

    4. Locate the public key that is blank and click Edit.

    5. Paste the new key into the modal text box.

    6. Click Save.

    7. After some period of time when you can confirm the old key is no longer being used, remove it from the sidecar. Learn more.

  3. Update the private key on the sidecar.

Note

Remember which key was updated so you can delete the old public key later.
