“2.1.2 An attacker could use a quantum computer to guess everyone's private keys.”

“It is very unlikely that quantum computing or any other field of scientific research will result in such a drastic rewriting of our understanding of the basic laws of physics.”

This is probably one of the easiest threats where he could have provided statistical analysis data, as private key collision is a very popular concern and there are numerous technical forums which have addressed it over the years.

He incorrectly states that “the private key is so large that it would take more energy than is produced by the sun in its entire lifetime to power a computer capable of guessing it.” This demonstrates a very poor understanding of not only Bitcoin, but cryptography and [quantum computing](https://www.ibm.com/communities/analytics/riskmanagement-blog/quantum-risk-management-schrodingers-dead

Copy-to-clipboard Bookmarklet

Create Bookmarklet (browser bookmark that executes Javsacript) to copy a given text to Clipboard.

This is the base javascript:

(function (text) {
  var node = document.createElement('textarea')
  var selection = document.getSelection()

Installation of NixOS with encrypted root

These are my notes on instaling NixOS 16.03 on a Lenovo ThinkPad X1 Carbon (4th generation) with an encrypted root file system using UEFI.

Most of this is scrambled from the following pages:

• Encrypted Root on NixOS - Nix Wiki
• Installing NixOS - Chris Martin
• Linux administration and use - Earl Douglas
• Installing NixOS on a ThinkPad W540 with encrypted root - Bluish Coder

Hardening the USB Armory

As a good crypto nerd, I usually use an entirely encrypted linux FS: / but also /boot using grub LUKS support. It's a good setup but it's not perfect, the BIOS and the bootloader are not protected.

I recently got a USBArmory and I wanted to apply the same (or a better) setup.

I found some useful links but no clear howto. So this is my setup.

language: java

env:
  global:

    - secure: "your encrypted SONATYPE_PASSWORD=pass"
