Generates a full hardcopy from a key, with checksomes to help with disaster-recovery
That's the same goal as the paperkey
tool, but (imho) better and more resilient :-)
Step 1 : generate a hardcopy of your key :
./hardcopy.sh KEYID > output.txt
Step 2 : create a rich-text document by copying the generated text 2-3 times
Step 3 : select a different font for each copy (to help discern zero vs capital-o, etc)
Step 4 : print a couple copies on a laser printer using quality paper
Step 5 : keep a copy at home, and give/send the other to a trustworthy person
Step 6 : Relax :-)
Below is a sample output, where i suppressed some lines with ...
to shorten it.
You can see all that is produced in the output, especially the "per line checksums" in the raw blocks (to be removed before import, of course) which tremendously help when checking input, in the event of disaster recovery.
The dumped private key is encrypted with the passphrase, so that is the reason the passphrase is dumped in cleartext too !
