To be clear, you only need some random bytes to seed your cryptographic PRNG. This should of course be gathered from the OS but after that you only need to reseed once in a blue moon. Of course you shouldn't write and maintain a CPRNG yourself but there are many widely used, maintained and scrutinized libraries for this purpose. For example, seeding ChaCha with 256bits will give you 1 ZiB of output before cycling. That should keep you going for awhile. |
