Hi Jouke,

If you are using the version 0.4.21 then the compressed and uncompressed private keys are interchangeable. Earlier versions did not understand the compressed keys and could not import them properly. I'll update the file contents to make it clearer.

You can see which version you are on in 'About MultiBit'.

The encryption format for the private keys is OpenSSL compatible - you can use openssl on the command line to encrypt/decrypt. See the bottom of:

https://github.com/jim618/multibit/wiki/Export%20and%20limited%20import%20of%20private%20keys

It uses the OpenSSL key derivation function and 256 bit AES.

Ah, github, didn't think of that

Thanks!

btw is it possible with multibit to import private keys from a paper backup? if so, how?

Sorry for your loss - the encrypted wallet code when it comes out will be better in this respect - it automatically creates encrypted private key backups.

There is help on importing a private key here:
https://multibit.org/help_importASingleKey.html

If you are doing a lot of private key work then I think Armory is better than MultiBit as it has the whole blockchain at hand and is more tailored to that kind of work. MultiBit only stores the very minimum amount of data (to keep things speedy) but for private keys you need to look through everything. For the occasional vanity key or paper wallet MultiBit is fine though.

In that file there is talk about a private key that starts with a 5. In my wallet there are keys that start with a K and a L, so doess that mean that multibit is using compressed keys? Are they interchangeble in the multibit wallet ie. can I used compressed and uncompressed together?

Also, what encryption is used on the passworded backup? I couldn't find it in the help files.

Have a look in the MultiBit user data directory (more details in the 'Troubleshooting help - https://multibit.org/help_troubleshooting.html) for any file called:

[your wallet filename]-[timestamp].wallet

If you were using the default wallet the filename the wallet filename will be 'multibit'. The timestamp will be something like 20130305104215 (it's the year-month-date-time).

If you have one, open it up in MultiBit and then go to 'Tools | Reset blockchain and transactions' and replay the blocks from a date before when your friend sent you the bitcoin.

Other than that you will need a backup or any exports of the wallet's private keys (that you can import into a new wallet).
Unfortunately in this situation the delete wallet is a secure delete which overwrites all the contents with nonsense bytes so you cannot undelete it from the trashcan or disk.

Also, if you have anything like the Macs time machine you might have a copy on that if you rollback to before the wallet delete.

Thank you

Unfortunately for me, this will have to be a hard lesson learned. didn't export any keys, and only had one hard drive for don't have a system restore point.

luckily was only 0.05....btc small amount in the big scheme of things, but at same time when i only have like .17.... btc in my main wallet it is big to me right now.

oh well life goes on. thanks for your help.

i deleted wallet that never had ant transactions. only thing done with it was set up 2 or 3 receiving keys. well i accidently had someone send me about 0.05+ coins to one of the addresses i made in this wallet. is there any thing i can do?

I have version 0.4.20

At the moment there is no coin control in MultiBit - currently the algorithm for choosing which of your transaction outputs to use is:

+ order all of your available outputs by age (oldest first).
+ add up you available outputs (oldest first) until you get to the amount you need, or a bit over.

You will thus spend from your oldest deposits first.

I must admit it is not that high a priority putting this in - when HD wallets come on stream you will end up with lots of (automatically generated) change addresses and you'll probably want to spend those by age or to minimize the fee or something like that.

Hi,

how can I create a new sending address in Multibit? In the "Send" tab I can only create a new receiver address to send bitcoins to, in the "Request" tab only my new receiving address can be created. Am I missing something?

I'm not sure what you mean.
To keep a record of who you want to send to, you make a new address on the Send tab.
For a new receiving address / private key, use the Request tab.

It's fairly similar to the Satoshi client in this respect.
Can you explain what you mean a bit more ?

Sure, when I send BTC from my wallet my sending address (I mean the address the BTC is sent from) is recorded in the blockchain as: XXXX (just an example), the receiver address is YYY.

Then when I send another BTC to the other address my sending address is recorded in the blockchain again as XXX, and the receiver address is ZZZ.

When I make a third transaction my sending address is again XXX and (of course) receiver iz BBB.

In other words - every transaction I make has the same sending address. I hope you understand what I mean. I would like to sent BTC from different adresses every time I make a transaction from the same wallet.

I can sugest something? support for other coins as well, i men, wallets for namecoin, litecoin... all in a single client, that whould be great.

I don't plan to put support for other coins into MultiBit because:

+ I want to keep it simple.
+ I believe we'll get the strongest network effect by concentrating on BTC.

You could get one of those coin's developers to fork it...

Yes, I was thinking of adding it in the 'receiving addresses' as an extra column.
I'll add it in the todo list for the next UI rework.

Do you have any plans to show how many bitcoins per address?

To me, it'd be interesting to see how much of my income was from mining,

BUT, if I ran a business, it'd be a great tool too see how much a client spent, right from the wallet.

Thanks

Is there any way to do some sort of reset/rescan? I have a few transactions that have been stuck at "seen by 1 peer. Not seen in chain" status for awhile. Also, my BTC balance shown is 4x higher than it should be for whatever reason.

I'm using the Mac 0.4.19 version.

Thanks!

Hi Gabbynot,

Yes there is a rescan option in the menu option "Tool | Reset blockchain and transaction"
The help for it is here:

https://multibit.org/help_resetBlockchain.html

If I use it I normally take it back to the transaction previous to the one that was causing trouble.

Wow, I didn't see that. That fixed the problem easily.

Thanks for answering an incredibly stupid question.
