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.
This provider will have logical resources that allow Terraform to "manage"
randomness as a resource, producing random numbers on create and then
retaining the outcome in the state so that it will remain consistent
until something explicitly triggers generating new values.
Managing randomness in this way allows configurations to do things like
random distributions and ids without causing "perma-diffs".
