A PEM-format RSA credential for securing requests to the Oracle Cloud Infrastructure REST API. Also known as an API signing key. Specifically, this is the public key from the key pair. The private key remains with the user calling the API. For information about generating a key pair in the required PEM format, see Required Keys and OCIDs.
Important: This is not the SSH key for accessing compute instances.
Each user can have a maximum of three API signing keys.
