Here is a brief overview of some security steps taken in creation of private keys for Finite By Design, LLC products (Proofs and Crypto-Cards). Please note that an internet connection is necessary for key pairing and network population, however, the private keys for f*D generated addresses are never exposed online. Private keys are only viewed once on our offline computer equipment (has never and will never be online), printed on a ‘dumb’ printer and then immediately destroyed.
- Download online client from source
- Launch online client to generate a new address
- Close online client
- Remove wallet.dat and put on thumb drive
- Delete data folder and uninstall wallet
- Remove thumb drive from online computer and insert to our offline computer (never has been or will be connected to the internet)
- Place wallet.dat from thumb drive into offline client (roaming folder)
- Open offline client
- Only at this point will I use the “dumpprivkey” command exposing the private key
- The private key is at this point printed using a ‘dumb’ printer
- All copies of the private key are immediately destroyed and the one printout is promptly inserted behind a tamper resistant hologram sticker
- The wallet.dat file is destroyed on the offline computer
