There is no difference between /dev/random and /dev/urandom in the Linux kernel, other than /dev/random blocks when the entropy estimate is low or depleted. Bot

There is no difference between /dev/random and /dev/urandom in the Linux kernel, other than /dev/random blocks when the entropy estimate is low or depleted. Both source them same CSPRNG, which is based on SHA-1. /dev/urandom is absolutely recommended for long-term keys.
