Title: Exporting private keys from old Core Wallet Post by: platorin on November 05, 2017, 01:05:55 AM Hey Guys. I would like to export my private keys from Core Wallet. Let's say I have several addresses with at least one incoming transaction on each. Would that mean I will have to a private key for each address individually, or would I rather receive one key for all addresses?
Thanks! Title: Re: Exporting private keys from old Core Wallet Post by: Spendulus on November 05, 2017, 03:23:01 AM Hey Guys. I would like to export my private keys from Core Wallet. Let's say I have several addresses with at least one incoming transaction on each.

You can dump them all as is, or move the coin to one key and then dump just that one.Thanks! Title: Re: Exporting private keys from old Core Wallet Post by: HCP on November 05, 2017, 04:44:28 AM Each address has it's own key... so, logically, if you have coins spread across multiple address, you're going to need to get multiple keys. (NOTE: Instead of using 'dumpprivkey' multiple times to get each private key, you can use the 'dumpwallet' command to just dump the whole wallet out to a file).
PROS: Free! Maintains privacy (none of the addresses will be linked) CONS: Time consuming, messy, possibility of missing a key/address Or... as Spendulus has suggested, just send ALL the coins in that wallet to a new address in that wallet, and just export that one key for the new address. PROS: Just one key to rule them all! :P CONS: Will cost a transaction fee... which could get large dependent on how many UTXOs you're trying to consolidate, plus you have to wait for confirmation... possible privacy implications Title: Re: Exporting private keys from old Core Wallet Post by: platorin on November 07, 2017, 05:34:24 PM Each address has it's own key... so, logically, if you have coins spread across multiple address, you're going to need to get multiple keys.

One more question - that command "dumpwallet" won't do anything to my wallet iselft or my bitcoins? It just "dumps" all data to a text file?PROS: Free!

On core 1 private key can have several address. Title: Re: Exporting private keys from old Core Wallet Post by: HCP on November 07, 2017, 09:42:16 PM Are you sure of that ? On core 1 private key can have several address. Technically, each HEX private key can be used to generate 2 addresses (compressed/uncompressed)... as far as I'm aware, Bitcoin Core currently deals only in compressed addresses... and when you dump the WIF keys, a WIF key has a 1:1 relationship with an address. The WIF starts with either "5" = uncompressed or it starts with a "K" or "L" = compressed.Unless you're referring to xprvs... aka "Master Private Key"... which are derived from the "seed". ???
