comment Reversing DJB2 Hashes
If you can do that, then you should have said so, since your reverse algorithm doesn't. $\hspace{.95 in}$

This is an alternative to your algorithm (and one that actually accounts for $\hspace{1.9 in}$ r being implicitly modded by $2^{32}$). $\;$

comment True Random Number Generator by milliseconds per keystroke (TRNG-Kms)
@xorcoder : $\;\;\;$ His previous comment does say that "CSPRNG is a subclass $\hspace{1.74 in}$ of PRNG and was of course implied.". $\;\;\;\;\;\;\;$

@marstato : $\:$ In fact, AES25 is even less precise than AES256. $\;\;\;\;$

comment True Random Number Generator by milliseconds per keystroke (TRNG-Kms)
er, I guess the last of those papers isn't actually helpful, since your data probably doesn't have that much entropy. $\:$ I would recommend using one of the middle paper's algorithms, since it seems likely to me that randomish key-presses would behave as a small-space source. $\;\;\;\;$

The problem is 1; an attacker must never see authenticated plaintext. $\;$
