What is the use of entropy (`/dev/random/) in android?

 

I read this blog post over here.

The post says that Chrome, map application uses

/dev/random

. I wonder why they use them. Is that

/dev/random

generates random numbers with the help of hardware?

Is this the case only in android or it happens to be in linux os too?

Thanks in advance.

 

Answer

You should check this other XDA article.

They say that

/dev/random

is not used by most of the applications and that the performance gains are probably due to boosting of the CPU speed.
