This resource generates a cryptographically-strong set of bytes and provides them as base64, hexadecimal and decimal string representations. It is intended to be used for generating unique ids for resources elsewhere in the configuration, and thus the "keepers" would be set to any ForceNew attributes of the target resources, so that a new id is generated each time a new resource is generated.
