To get good entropy install OpenBSD[1] on a VM with network adapter
permanently disabled and use /dev/arandom.  If possible use a PEM pass
phrase so you have the countermeasure of "forgetting the password" if
under a lavabit attack.  RSA 2048 bit  theretically will require quantum
computers to crack unless someone comes up with more efficient math to
crack the RSA algorithm.
