When generating private keys with `ecparam` or `genrsa` in OpenSSL, it
is possible to use the parameter `-rand file.dat` where file.dat is used

I believe that if you give the option "-rand file.dat", then the RNG is
seeded only from file.dat (i.e. it is not an additional seed -- it is
the whole seed).
I would like to generate private Ed448 and Ed25519 keys with an
additional random source provided as file. Is there a way to do that?
I'm using version 3.1.0 btw.
You could try using a config file:

Have a look at the "random" section and the info about setting the
variable "seed".
