Rotate Sidecar Authentication Keys

ALTR supports 2 public keys per sidecar to enable uninterrupted key rotation. Once an old key is no longer in use, you can safely delete it.

To rotate sidecar authentication keys:

1. Generate a new RSA key pair — see Sidecar Authentication for a key-generation example.
2. Save the new public key in ALTR:
   1. Log in to ALTRNet through your identity provider (IdP).
   2. Select Settings > Sidecars in the navigation menu.
   3. Click the sidecar to view its details. Under Public Keys, there are 2 key fields.
   4. Locate the public key field that is blank and click Edit.
   5. Paste the new key into the modal’s text box.
   6. Click Save. ALTRNet adds the new public key to the sidecar.
3. Update the private key on the sidecar.

Note

Record which key field you updated so you can remove the old public key later.
