comment Block cipher mode with diffusion on ciphertext
You might want to look into OCB. It provides verification in a "strong" sense (i.e., AEAD) with performance not too far off from CTR mode. See web.cs.ucdavis.edu/~rogaway/ocb/news for a portable optimized implementation and web.cs.ucdavis.edu/~rogaway/ocb/license.htm for license info (free in almost all cases).

comment Is Pseudo-Random Generator (PRG) in OpenSSL uniformly distributed?
"Cryptographically Secure, which means it passes statistical tests". To be clear (and I don't mean to imply Security Aficionado is unaware of this issue), Cryptographic security requires much more than that. Standard statistical tests are quick and dirty, and look for very generic types of "non-randomness"; cryptographic security requires outputs to be indistinguishable from random even against computationally intensive tests that are targeted specifically at the algorithm in question.
