Majority of web pages and blog posts I’ve read suggests to use /dev/urandom Even the man page was updated to state that this is what you want unless under specific circumstances: The /dev/random interface is considered a legacy interface, and /dev/urandom is preferred and sufficient in all use cases, with the exception of applications which require randomness during early boot time; for these applications, getrandom(2) must be used instead, because it will block until the entropy pool is initialized.
