Module rand

Miscellaneous functions related to getting (pseudo) random numbers and strings.

NOTE! This should not be used when you do need real random numbers such as for encryption but will probably be suitable when you want locally unique ID’s that will not be shared over the network.

rand_bytes

Get a pseudo random vector of len bytes.
