I doubt that 4 star generals are doing that type of thing. One option is to make your program (or server) ask for this keystore passphrase upon startup. One significant benefit of aes is that the algorithm is public, and its use is unrestricted, with no royalties or license fees owed to the inventors or the government. Sender non-repudiation (the inability of a sender to refute that they signed something encrypted with their private key). I wouldn't get too caught up in what i said about everything boiling down to "what you know" authentication because it's just being picky (or annoying) and doesn't really provide much value to debate these things (imo at least).
