comment What tests can I do to ensure my PRNG is working correctly?
NIST has its own test suite, called "Statistical Test Suite" (STS). It is downloadable from csrc.nist.gov/groups/ST/toolkit/rng/documentation_software.html.

comment Why doesn't preimage resistance imply the second preimage resistance?
Look at this paper: Cryptographic Hash-Function Basics: Definitions, Implications, and Separations for Preimage Resistance, Second-Preimage Resistance, and Collision Resistance.

comment Is it safe to encrypt a public key alongside a message with AES?
@PaĆ­lo, shino: Thanks a lot for the appreciation. I thought it was too short to be made an answer, thus I left it as comment. Moreover, Marsh Ray's answer complements mine, and is long enough ;)

AES is secure against known-plaintext attacks, though I suggest not using ECB mode in the case you're going to encrypt M+P. Using CBC or CTR modes seem to be OK.
