libprngwrap

What is it?

In sort libprngwrap enhances the PRNGs from libc. libprngwrap replaces the [s]rand, [s]random and [*]rand48 library calls with functions that get random values from /dev/urandom. This is supposed to be more secure.
One could, for example, use the LD_PRELOAD environment variable or add the complete path to this librarty to /etc/ld.so.preload. In the last case, every program on your system will use this wrapper.
