As a
cryptocurrency and finance practitioner, I'm curious about the use of `/dev/urandom` within the crypto/Rand subsystem. Could you elaborate on the steps necessary to access and utilize this device for generating cryptographically secure random numbers? Understanding its integration within crypto/Rand would be particularly valuable for me in terms of securing cryptographic operations. Are there any specific APIs or methods I should be aware of to access `/dev/urandom` efficiently and securely within this subsystem? Additionally, I'm interested in knowing if there are any considerations or best practices to keep in mind while using `/dev/urandom` for cryptographic purposes.

By default, the `init()` function in `crypto/rand` configures it to use `/dev/urandom` as the source of randomness.

`/dev/urandom` is a non-blocking pseudorandom number generator in Unix-like systems, including Linux, OS X, and FreeBSD.

This implementation is deemed sufficient for cryptographic purposes in many cases, as it provides a sufficient amount of entropy for most applications.
