Title: priv key to QR generator Post by: pawel7777 on March 28, 2015, 10:07:54 PM Dumb question. If I have private key only as a number and I want to upload it to android wallet (which only allows to scan QR of priv key), what's the best (safest) way to convert key number to QR code?

You can find a few browser extensions that can do that. Title: Re: priv key to QR generator Post by: pawel7777 on March 28, 2015, 10:39:09 PM Have you searched "QR code generator" on google? You can find a few browser extensions that can do that. I have. The top result is this one: http://www.qrstuff.com/ It has an option of 'bitcoin' but it's for public addresses not priv keys. Obviously it's not a smart idea to submit your priv key on any 3rd party website. Hence my question.

The more secure way would probably be to use something like https://www.bitaddress.org download it and use it offline (save as.. or github repo). Title: Re: priv key to QR generator Post by: pawel7777 on March 28, 2015, 11:09:19 PM Thanks for replies.
Using bitaddress.org offline seems the easiest option. Didn't notice before they allow to upload existing key, thought it only generates new ones. You learn something new everyday...

Best one is google api: https://developers.google.com/chart/infographics/docs/qr_codes |
