All you would ever need is 256 bits, and even that is more than enough for the average private key (which is about as secure as a 112 bit symmetric key, at least for RSA 2048). Any further needed random data (since it is true that you need more than 256 bits worth of data) can be generated with a CSPRNG fed those initial 256 bits. | |
