Initial card setup

Procure some PKCS15 smart cards. Do not get Java Cards. Get "eToken" cards. They're CDW Part #1537376 . I'm sorry you'll have to deal with CDW but that's life sometimes.

Install the following packages:

• pesign
• pcsc-lite-ccid
• pcsc-tools
• pcsc-lite
• opensc
• nss-tools

Create the CA

1. Turn off shell history for some commands.

export HISTCONTROL=$HISTCONTROL:ignorespace

1. Use nss-tools' certutil to generate a CA key ("fedora-ca.p12")

eddie:~$ mkdir db
eddie:~$ cd db
eddie:~/db$ certutil -d $PWD -N
Enter a password which will be used to encrypt your keys.
The password should be at least 8 characters long,
and should contain at least one non-alphabetic character.

Enter new password: <just hit enter here>
Re-enter password: <just hit enter here>
eddie:~/db$ certutil -d $PWD -S -s "CN=Fedora Secure Boot CA" -n Fedora\ CA -x --keyUsage certSigning,crlSigning --nsCertType objectSigningCA -t ,,c -k rsa -g 2048

A random seed must be generated that will be used in the
creation of your key.  One of the easiest ways to create a
random seed is to use the timing of keystrokes on a keyboard.

To begin, type keys on the keyboard until this progress meter
is full.  DO NOT USE THE AUTOREPEAT FUNCTION ON YOUR KEYBOARD!


Continue typing until the progress meter is full:

|type a bunch of crap until OMG IT'S FULL OF STARS|

Finished.  Press enter to continue: <just hit enter here>


Generating key.  This may take a few moments...

eddie:~/db$ # we're going to need the DER version of this for shim. '''Store this some place we'll have it later.'''
eddie:~/db$ certutil -d $PWD -L -n "Fedora CA" -r > fedora-ca.cer
eddie:~/db$ pk12util -d $PWD -o fedora-ca.p12 -n "Fedora CA"
Enter password for PKCS12 file: <just hit enter here>
Re-enter password: <just hit enter here>

1. List the certificates to be sure

eddie:~/db$ certutil -d $PWD -L

Fedora CA                                                    u,u,cu

1. Initialize smart cards

# Make sure pcscd is running
service pcscd start

1. Insert your Smart Card
2. Pick 4 random 8-digit numbers for PIN/PUK/SOPIN/SOPUK. Write them down.
3. Initialize each card as a pkcs15 card

1. Repeat steps 4 through 8 for a second card, omitting "modutil -dbdir /etc/pki/pesign -add ..." which won't need repeating.

1. Remove stuff we don't want the world to see

eddie:~/db$ rm fedora-ca.p12
eddie:~/db$ certutil -d $PWD -D -n "Fedora CA"

1. Verify that we really removed it from the filesystem because that's incredibly important:
