How to export private keys from QT and import into blockchain.info ?

[forzendiablo]

Currently i dont have enough space to run Bitcoin core yet i need to get my bicoins to use.

I know Blockchain.info lets you import other wallet keys.

What command i need to run on QT [yes i can start it, just cant fully sync it] to get my BTCs into blockchains site?

Please don't use Blockchain.info. Many people's wallets have been hacked because of Blockchain.info's fault. If you can't use Bitcoin Core, why don't you use thin clients like Electrum and Multibit HD?

To export private key, run dumpprivkey address. If your wallet is locked, you will have to unlock your wallet first by running walletpassphrase passphrase timeout (timeout is in seconds).

Eg:-

walletpassphrase pass1234 300  - This will unlock a wallet for 300 seconds(5 minutes).
dumpprivkey 1MZakirz92c76pK6BNy1NAEmbWYpDcP7mh  - This will show private key for 1MZakirz92c76pK6BNy1NAEmbWYpDcP7mh. (If this address is in the wallet.)

P.S. You will have to export private keys one by one.

You can also use pywallet to dump all the private keys at once and paste the output into the blockchain.info wallet.

You will need to have Python installed.
