How do you recover a Multibit Classic or Multibit HD wallet if you only have a .key .wallet or .cipher file?
In the case of Classic, you can decrypt the .key or .wallet file using OpenSSL
If you have a HD mnemonic it is possible to use the words together with tools like iancoleman.io to decrypt the private key using the right derivation path.
