Best client for importing multiple private keys?

[Dabs]

each string will trigger whole blockchain rescan

That's what the "false" at the end of each line is for. No rescan.

I'm going to try this, the last time didn't work because I'm using an encrypted wallet.

it worked for unencrypted.
Thank you!

Yes, that's the idea. But I need to import 5000~10000 keys. I don't want to be doing that one by one.

what?so many keys?   may i ask why u need them?

For a new website that will probably have a few thousand users (with deposit addresses) and of course change addresses.

did anyone finally figure out a way to do this in bulk without triggering rescan ?

say for 250 addresses

As amaclin and Dabs on this thread already said, you need to add a third parameter false to importprivkey

Code:

bitcoin-cli importprivkey privatekey-1 somelabel false
bitcoin-cli importprivkey privatekey-2 somelabel false

Works fine even for 2000 addresses.  However, the next rescan will take some time, especially if there were many transactions.

how much rescan time we can expect for 1000 private keys imported to wallet with parameter false to importprivkey command

So, anything available in those addresses will be sent ? How do I send partial amount ? Moreover, is not there any parameter to mention the mining fee ? Tx without mining fee may take a long to confirm !!!

The import takes about a minute, but there is no rescan triggered.  

If you need the accurate balance, you have to rescan manually afterwards (it may be enough to import a private key with third parameter true, but I'm not sure).  With my 2000 weak keys (some of them had a lot of transactions) it took a full day to rescan the wallet.  My wallet.dat is about 500 MB.  If your keys are fresh and haven't occured on the blockchain, there is no need to rescan.

No, the commands send no transactions, they just put the private/public key into the wallet.  The rescan will just search for transactions and recompute the balance.  I don't think that bitcoind has support for sweeping an address.  You can of course just ask for the balance and then send that amount the usual way to a new address, e.g. using bitcoin-qt.

I am looking to automate a process of importing a private key to a client, send a certain amount from the client then delete the private key before moving on to the next private key.

Currently I am figuring I can set up a fresh wallet.dat, import a private key and send the BTC, then overwrite the wallet.dat with a copy of the fresh wallet.dat.

There should be a better way.

Blockchain works fine.

If you are only interested in balances, you can scan the utxo set and that only takes a minute but I don't know if it's possible with bitcoin core.

Looking for changing addresses to a website in bulk, spent lot of time to figure out. I would have visited this section often.

I tried Bitcoin Armory to import multiple priv. keys (few thousands). It was fast. It took about 15 mins for all the process. and the rescan was very quick.

Well, I'm trying the same with 900 private keys, but it takes more than 1,5 hour total already.

Code:

importprivkey "5yourveryveryveryverylongprivatekeystring" "my-new-key1" false
importprivkey "5yourveryveryveryverylongprivatekeystring" "my-new-key2" false
importprivkey "5yourveryveryveryverylongprivatekeystring" "my-new-key3" true

The last true triggers the rescan, other false are skip that. So you scan once for balance at the end.

I assume this is a bitcoind implementation?
