Unlike /dev/urandom, /dev/random blocks HTTPS and SSL/TLS functions if there is not enough entropy to perform the functions. The functions resume after the system generates enough entropy.
Note: If /dev/random blocks during an installation or upgrade, the system waits up to 10 minutes for more entropy to be generated before halting the operation.
Tenable does not recommend using /dev/random unless required by your organization.
