Working with API Signing Keys
On Private Cloud Appliance, if you need to use the OCI CLI or make REST API requests, you must have an RSA API signing public and private key pair in PEM format.
API requests are signed with the private key, and the public key is used to verify the authenticity of the request. The private key is stored locally and the public key is uploaded to a user account. You can have a maximum of three (3) public keys per user account.
Note
The API signing key pair is not the SSH key that you use to access compute instances.
