Title: Public -> Private -> Public doesn't give same address?
Post by: utdrmac on January 06, 2017, 05:52:14 PM
Hello,
I've got several addresses in my blockchain.info account. I decided to import them into Electrum. I used the private key from bc.i for address 1xxxx.... but when I imported it, the resulting address showed 1yyyy... It was completely different! I even re-imported the same private key back into bc.i and it too imported a completely different address (same address that Electrum showed).

What the heck happened? Can I no longer use those older addresses? Some are vanity with custom prefix that I'd like to keep using.

Yes, they are all at least 2-4 years old. Did some calculation standard change recently?

Thanks!

When getting the private keys of imported addresses in blockchain.info, you'll get completely different private keys instead. Follow the instructions here (https://bitcointalk.org/index.php?topic=1600645.msg16079990#msg16079990) to convert it.

Awesome! Thank you! Had to bust out a windows vm for this but it was painless otherwise.
