Title: Hotfix for a potential security problem in randBytes()

I removed the usage of XOR to mix different sources and I removed the /dev/urandom. In the previous implementation with Mcrypt() XOR /dev/urandom we could have a potential problem if the output of the sources is the same (because also Mcrypt uses /dev/urandom).
