Sidecar Authentication

The sidecar authenticates to ALTR’s SaaS control plane using key-pair authentication. Customers must generate a valid RSA key-pair before deploying a sidecar.

RSA Key Requirements

The following are requirements when generating the key pair:

  • Algorithm: RSA 2048 or higher

  • Private key: non-password-protected, PEM-encoded, PKCS#8 format

  • Public key: PEM-encoded, PKIX or PKCS#1

The private key can be mounted ALTR sidecar to “/app” with the name “private.pem”. Alternatively, you can specify a different key location as an environment variable.
