| /* | ||
| Package rpc is a provider that defines an HTTP request/response contract for handling BMC interactions. | ||
| It allows users a simple way to interoperate with an existing/bespoke out-of-band management solution. | ||
| The rpc provider request/response payloads are modeled after JSON-RPC 2.0, but are not JSON-RPC 2.0 | ||
| compliant so as to allow for more flexibility and interoperability with existing systems. | ||
| The rpc provider has options that can be set to include an HMAC signature in the request header. | ||
| It follows the features found at https://webhooks.fyi/security/hmac, this includes hash algorithms sha256 | ||
| and sha512, replay prevention, versioning, and key rotation. | ||
