How to import Multibit.wallet into bitcoin-QT ?

If you do an export of the private keys unencrypted you get a file with all the private keys in. It's the first column.

Then it will be 'import private key' in the console inside Core to import them.
Not exactly sure how to do this as I've not done it but the export is the first step.

Once you have done the import make sure you secure delete the exported private keys to stop anyone accessing them in the future.

You will need to do it for each of the private keys you exported from your MB wallets.

There's also an importwallet RPC command that I think can directly read the key export file (with all the addresses at once) created by MultiBit, but I haven't tried it in a while and I could be wrong.

If some one heard that please help /

I have tons of private key i can't do it separately .

See here: https://bitcointalk.org/index.php?topic=712047.msg8055660#msg8055660 (https://bitcointalk.org/index.php?topic=712047.msg8055660#msg8055660)

As I said above, I believe that the MultiBit key export format is the same as the Bitcoin Core dumpwallet/importwallet format.

Then write a script for it.  The keys are all exported to a file called multibit.key.  Parse that file for each key and pass it to bitcoin-cli using the same command I shared above (except put "false" instead of true so you don't rescan every key).
