cprima / initializing-NitrokeyHSM.sh
Created January 1, 2018 17:18
Initializing the Nitrokey HSM (Ubuntu 16.04)
#!/usr/bin/env bash
#/**
# * A bash script to initialize a Nitrokey HSM in a basic way.
# * Does nothing on a Nitrokey HSM that was ever initialized before.
# * Its main purpose is to validate user input, especially the -so-pin.
# * I wrote it to make me read the docu carefully. ;)
# *
# * What the script does:
# * - uses readline with plain input, and not "enter twice and compare"
# * -- so "secret input" are visible on the screen

Scripted version of the Nitrokey-based EC CA from the article at https://medium.com/where-the-flamingcow-roams/ec-ca-redux-now-with-more-nitrokey-729061e1b7c9

Two versions:

  • make_ca-rsa.sh with RSA keys
  • make_ca-ec.sh with the original elliptic curve keys
