yeah, i'm gonna wait for other people to review that mod first...
There seems to be another method another person is trying in the thread to add a symlink between urandom to random. Might try that too. A response from the developer from the OP in the XDA thread (from Reddit)
Seeder author here.
The reason I didn't rm /dev/random && mknod /dev/random c 1 9 (or symlink as you suggested) was because, at least in theory, stirring lower-entropy data into /dev/random (only when needed) should result in higher quality random data.
That is, most of the time, /dev/random has sufficient high-quality random data to pull from. It's only when we run out that it's a problem, and only then is large amounts of lower-quality data pulled in.
Reading directly from /dev/urandom is probably safe, cryptographically, even for keygen. It's unlikely anyone would ever use that as an attack vector; probably easier to attack the OS directly, right? But, rngd was the approach I took for Seeder, and it works for me.
