Topic: Found 3 MultiBit HD Wallet Backup Files (mbhd-[..].zip.aes) + 12-Word Seed (Read 75 times)

If it's related to that issue, then it's very easy to reproduce in IanColeman's BIP39 tool.

Here's how to (only use this to reproduce that issue):

• Follow the link to the issue in your reply and take note of the "mnemonic sentence" and the (expected/actual) addresses.
• In IanColeman's tool (link), paste the sample mnemonic: skin join dog sponsor camera puppy ritual diagram arrow poverty boy elbow.
• Then copy the result "BIP39 Seed" which is: e8b9a1929f72ccd322b5241dd9a62c08d02129c386de9dc505bb4decc8eb33ffd89575a037be4fb b9a4cf258bff88bbf89745f2f523298e98810e5099502d1b6
• Scroll up and tick "Show entropy details" and paste the BIP39 Seed in "Entropy", you'll see that the BIP39 mnemonic will match the long 48-word mnemonic presented in that issue.
• To derive the addresses and private keys, go to 'BIP32' tab below and select "MultiBit HD" in 'Client' drop-down menu.

Note: If you want to try this on your actual seed, use it on an "Air-Gap" machine and read Offline Usage notes below that BIP39 tool.

I've never used it, so I can't comment on your case from experience. But this is what I've collected on Multibit over the years, see if it helps:

Hello everyone,

While going through an old hard drive, I discovered a folder containing three MultiBit HD Wallet backup files (mbhd-[...].zip.aes) and a screenshot of a 12-word seed phrase along with a datestamp (XXX/XX).

I remember having a small amount of BTC associated with one of these accounts. However, when I tried importing the seed phrase into Electrum, the generated accounts were empty and showed zero transactions.

After some research, I found that certain releases of MultiBit HD had an incorrect implementation of BIP32 (https://github.com/Multibit-Legacy/multibit-hd/issues/445). This might be why I'm unable to restore the wallet using the seed phrase alone.

From what I've read, it's possible to decrypt the backup files using the seed phrase. However, I also came across a post from an old MultiBit HD dev stating that the AES key used for decryption is derived from the seed phrase. I'm unsure how the seed phrase is transformed into the AES key ("MultiBit HD dev here. The cloud backups are encrypted with an AES key derived from the wallet words only, not the password." : https://bitcoin.stackexchange.com/questions/38948/how-do-i-restore-a-wallet-from-a-backup-file-in-multibit-hd#comment45918_38966 ).

Some additional information:

- I do not have access to the original MultiBit HD software

- I do not remember the addresses

- The folder name is "BitCoinCloud"

Has anyone successfully restored funds from MultiBit HD backups under these circumstances?

Thank you in advance for your help!
