comment Random Number Generation with a Entropy pool versus Seed
@user4982 Thanks. I was unaware of the NIST specs.

comment Random Number Generation with a Entropy pool versus Seed
@Reid Thanks. I do already have this implemented but considering its really new I am deciding to back the RNG with something slightly better than Math.random as a fallback. I did look at SJCL but as I've already started porting, I will simply continue porting it. This was more of a side question :)

comment Random Number Generation with a Entropy pool versus Seed
@HenrickHellström The difference between a CSPRNG and a PRNG is simply that one can be predicted and one cannot. I may want to make a poker game where I do not wish to have the randomness predicted so a CSPRNG would be ideal.

Ah ok, sorry, I thought you were referencing the image only. That would answer my question. Post it as an answer and I'll mark it as correct! Sorry for wasting your time -.-

@StephenTouset but in decryption it doesn't actually use the IV at all for the actual cipher transformation, just for stripping it from the plaintext at the end.

comment Does the IV need to be known by AES (CBC mode)?
In fact that Wikipedia article confirms what I said. If the IV is the same length, and is prepended or appended to the plaintext, then you could simply strip those bytes off the end or from the front after decryption. The only reason the decryptor needs the IV (by the looks of that article) is to know what bytes to strip!

I never understood exactly what CBC was doing tho. Did it take the unencrypted previous block as the IV for the next, or the encrypted previous block as the IV for the next?

comment AES encryption with shared IV
Paulo, I understand I asked this a while ago, but you mean I should use a different encryption key for each direction of packets?

Patience really isn't an issue. I was thinking this at a more, FBI wants information, goes downloads encrypted files of suspect user, requests from mega their encrypted key and a hash of their password, FBI uses super duper mega powerful computer to bruteforce hash.
