Features

• Generate a list of valid last words

  Insert a mnemonic missing the last word and a list of possible valid last words (that fulfill the checksum) is showed.

• Generate extended keys

  Insert entropy or mnemonic to show extended root keys.

• Generate mnemonics

  Insert entropy and optional passphrase to generate a mnemonic in any of the languages supported in bip-0039.

• Generate multiple mnemonics based on a list of valid words

  Insert 12, 15, 18, 21 or 24 valid words in any supported language and flag -g to show multiple mnemonics with valid checksum.

• Generate seed

  When hexadecimal entropy is inserted the tool show the seed to.

• Passphrase

  Optional passphrase can be used with the entropy or mnemonic for additional protection.

• Suggestions

  Show suggestion of a valid mnemonic word if one invalid is inserted.

• Support all languages specified on bip-0039

  • English
  • French
  • Italian
  • Japanese
  • Korean
  • Portuguese
  • Spanish

• Transposition

  Insert mnemonic and target language flag to result in words in the same 'position' on the new word-list.

Help

Enter optional language and hexadecimal entropy with optional passphrase or
enter a list of mnemonic words with optional passphrase to see information
about it. It can show a list of valid last words to fulfil a list of mnemonic
words missing the last one. Generate mnemonic using a list of valid words.
