Thanks Title: Re: How to generate qr codes for address and private keys? Post by: smeagol on December 16, 2013, 09:50:14 PM Is there a service which can convert plaintext addresses and private keys into qr codes? Thanks I found this: https://github.com/casascius/Bitcoin-Address-Utility Is there an already compiled version? I don't want to install the deps.

Of course, to ensure more security, you can save the website to disk and disconnect the machine from the internet (or better yet, copy the saved page to an offline machine) before you input your private key.

I already have a vanity address and a priv key, so I would like to convert that. Title: Re: How to generate qr codes for address and private keys?

Post by: Altoidnerd on September 08, 2015, 05:28:00 AM Using the new bitcoin-core binaries in linux (be sure you have qrencode installed):
Code: addr=$(./bitcoin-cli getnewaddress) && ./bitcoin-cli dumpprivkey $addr| qrencode -o ~/Desktop/$addr.privkey.png && echo "private key dumped for: "$addr See http://altoidnerd.com/2015/09/06/how-import-a-bitcoind-address-private-key-into-breadwallet-ios-with-a-qr-code-using-bitcoin-core-for-ubuntu-linux/ (http://altoidnerd.com/2015/09/06/how-import-a-bitcoind-address-private-key-into-breadwallet-ios-with-a-qr-code-using-bitcoin-core-for-ubuntu-linux/) Keep in mind the above snippet generated a new address. You can use and address you have in mind e.g. "address": Code: addr="address" && ./bitcoin-cli dumpprivkey $addr| qrencode -o ~/Desktop/$addr.privkey.png && echo "private key dumped for: "$addr Or if you have the private key as a string = "privkey": Code: key="privkey"; echo $key | qrencode -o ~/Desktop/mykey.png && echo "private key qr mykey.png created for $key |
