hello

I know this question was asked very often, but without a real solution for me.

The point is this i still have a multibit CLASSIC wallet and want to get the BCH.
I downloaded the wallet from bitcoin.com and wanted to import my key, but it says wrong password. i made a key without pw but it didn't let me import. I think the problem is ether that the file is multibit.key? or that is has not this mnemonic phrase password?
Could someone please help me on that, i am not technically.
And no I dont want to try services like electrocash etc.

Thank you!

You don't have a seed phrase on multibit classic, it's multibitHD that has the seed - so you haven't lost anything there.

When you open the private key, what does it start with? Can you work out what format it's in, if it's plain text in a WIF format which is probably what it'd be exported as then it should begin with a L, K or a 5. If the key begins with a U, that means it's encrypted using bip38 encryption (as far as I know that's the main letter that encryption links to but it may link to others as well).

Can you view the key in the multibit wallet and get it from there?
If that's the wallet that you want to use and you trust the most then stick with it, if there are compatability issues and another client is needed later then you can come back to using that afterwards (and if you distrust/dislike electroncash and you are orced into using it because nothing else works with your current wallet, you can always sign transaction offline and broadcast it from another computer so no one has access to anything - but you).

If you exported your private keys from MultiBit Classic... you must ensure that you do NOT encrypt the export file using a password... otherwise, they multibit.key file will be encrypted and unable to be read by any other application/wallet and will look something like this when you open it in a text editor:




To get the private keys in plain text, use the "Tools -> Export Private Keys" option in MBC and then set it up using the following guide:


and then click the "Export Private Keys" button.


If you do it like this, then your multibit.key file should be a plaintext file that you can open in notepad etc to get the Base58 encoded "WIF" private keys that you should be able to import into the BCH wallet of your choice:


NOTE: due to all the added info in the .key file (# comments and DateTime stamps etc), you'll most likely need to copy/paste the keys into your wallet application... I don't know of any wallets that will simply import the .key file directly

Thats exactly my problem. I made it just the way you said. But if its without password, i cant import!?

I also did with password and I always get this, although the password is correct. Do I need to make a new file to import, like wallet.key?

Your problem is that the two applications (MultiBit and bitcoin.com wallet) are creating and trying to import two different file formats.

MultiBit outputs either a plaintext file with your private keys or an OpenSSL encrypted file... Whereas bitcoin.com wallet is wanting an AES encrypted JSON wallet file to import.

The result being that you can't import your MultiBit keys into bitcoin.com. You'll need to use a different wallet like Electrum/ElectronCash that allows you to import private keys in WIF format... Or you'll need to sweep the keys into the wallet you want to use.

I can't find a sweep option on Bitcoin.com wallet... So if you're set on using bitcoin.com wallet you'd need to setup the sweep using another what like Electrum and just change the destination address to your Bitcoin.com wallet address...

Given that you're doing this for BCH, you'd probably need to be using ElectronCash if you're trying to send to a BCH wallet
