Now follow some CSPRNGs. It is important to remember that, as with everything cryptographic, it is best <em>not</em> to homebrew it if you are planning on actually using it. There are many ways things can go wrong, and the more complex the algorithm, the more chances of you making a mistake. Of course, for hobby uses it's perfectly fine; just don't go online banking with your handmade TLS key source. |
