* To recover your Bitcoin wallet without a Digital Bitbox, enter the wallet backup text and password in the above boxes, click 'generate', and import the recovery key into the Electrum software wallet.
* To recover Ethereum without a Digital Bitbox, enter the wallet backup text and password in the above boxes, click 'generate', and enter an Ethereum private key into MyEtherWallet. The order of private keys corresponds to the order of public addresses when 'viewing' a wallet in MyEtherWallet.
* The backup is saved as a PDF file on the micro SD card for convenience. Plug the micro SD card into a trusted printer if you wish to also make a paper backup.
* To load your own wallet into a Digital Bitbox, put the PDF file on the micro SD card inside a folder named 'digitalbitbox' in the root directory. Then, insert the SD card into the Digital Bitbox, and load your wallet using the desktop app. High quality randomness is crucial! Otherwise, a thief may be able to guess your key and take your coins.
* A wallet is generated from the backup text and password using a modified BIP39 procedure. In particular, PBKDF2 strengthening is done twice (22,528 total rounds) for stronger protection.
* Standard wallet addresses are generated following the BIP32 and BIP44 specifications. The BIP32 extended master private key is m. Electrum recovery keys are generated with m/44'/0'/0'. For a multi-signature wallet, the base BIP32 key path is m/100'/45'/0'. For Ethereum, the base BIP32 key path is m/44'/60'/0'/0. The tool generates Ethereum keys m/44'/60'/0'/0/0 through m/44'/60'/0'/0/19.
