This can take anywhere from a few seconds to more than a minute. +A few (Linux, NetBSD and Solaris) offer a choice between blocking and +getting an error; in these cases, we always choose to block.</p> +<p>On Linux (when the <code>getrandom</code> system call is not available), reading from +<code>/dev/urandom</code> never blocks, even when the OS hasn’t collected enough +entropy yet. To avoid returning low-entropy bytes, we first poll +<code>/dev/random</code> and only switch to <code>/dev/urandom</code> once this has succeeded.</p> +<p>On OpenBSD, this kind of entropy accounting isn’t available, and on +NetBSD, blocking on it is discouraged. On these platforms, nonblocking +interfaces are used, even when reliable entropy may not be available. +On the platforms where it is used, the reliability of entropy accounting +itself isn’t free from controversy.
