I'm new to the
/dev/urandom pipes in general and have an application calling from
/dev/urandom which I'm attempting to inject entropy into. I'd prefer not to change the source for this application, but an additional process calling
rngd -r /path/to/file from what I can tell appears to inject entropy into
/dev/random and increment the size such that it can unblock.
Now my question is: will
rngd -r /path/to/file inject into
/dev/urandom in parallel to
/dev/random or is it limited to
If the answer is no, is there a similar utility which will inject into
/dev/urandom - or even better - prepend bits to it such that the machine's PRNG is bypassed with the random entropy entirely in userland?
