This week we're chock full of questions! Why is my new ValiDrive freeware not published yet? Why did Apple quietly remove PDF rendering from the Mac after 39 years? Has the NSA been hacking China? What mistake did Microsoft recently make that would require the use of a bigger hard drive? Why did Signal just announce their use of post-quantum crypto? What's the big hurry? Is it possible to create a new web browser from scratch? And if not, why not? Does public key crypto really go both ways? Can pure math generate pure random numbers? One of our listeners believes he has. Could encrypting an entire hard drive then throwing away the key be used in place of the random noise wiping I'm a big fan of? Why hasn't the Unix time problem been fixed yet? Or has it? Will all of the stolen LastPass vaults eventually be decrypted? Am I really leaving Twitter? And, finally... why in the world is this episode titled "We Told You So!" ? The answers to those questions and more will be revealed by the time we're done here today. Welcome to episode #941 of TWiT's Security Now! podcast.
