Groestlcoin BIP39 tool: an open source web tool for converting BIP39 mnemonic codes! Groestlcoin BIP39 is a tool for converting BIP39 mnemonic phrases to addresses and private keys.

Enter your BIP39 phrase into the 'BIP39 Phrase' field, or press 'Generate Random Phrase'. Use the correct derivation path and word count.See the table for a list of addresses generated from the phrase. Toggle columns to blank to easily copy/paste a single column of data, eg to import private keys into a wallet or supply someone with a list of addresses.Changelog BIP39 tool 0.3.9:• Add coinomi to BIP32 tab• Add ledger client to BIP32 tab• Add groestlcoinomi client to BIP32 tab• Add Trezor client to BIP32 tab• Add Safe T mini client to BIP32 tab• Add Groestlcoin Core to BIP32 tab• Add Groestlpay client to BIP32 tab• Add Groestlcoin Samourai client to BIP32 tab• Display version number in top right• Change entropy Strength to Time To Crack• Groestlcoin ticker is now also displayed• BIP49 support• Refactor method to clear old data from the display• BIP44 'purpose' and 'coin' fields are readonly• Tab order is alphabetical• GroestlcoinJS library upgrded to v3.3.2• Bugfix: Clear old seed when mnemonic is changed• Improve showing feedback for pending calculations• Show error when using xpub with hardened addresses• Rename variables for clarity between BIP49 and P2WPKH Nested In P2SH• Tidy up code with consistent use of commas and semicolons• QR Codes use correctLevel 3 instead of 2• Update compile script to work across python 2 and 3• Add BIP49 to More Info section• Reword entropy text to indicate using a single source only• Detect and warn when entropy is filtered / discarded• List alternative tools• Remove unused translations and library• Use new xpub/xprv prefixes for Segwit BIP49• Allow more rows to be generated starting from a custom index• BIP141 tab added for full segwit compatibility• Update bootstrap from 3.2.0 to 3.3.7• Update jquery from 2.1.1 to 3.2.1• Show list of word indexes• Populate entropy field with hex value used from PRNG• Move application-specific css into own file• QR codes with accents work correctly by replacing jquery.qrcode with kjua• BIP84 tab for derivation path• CSV tab for derived addresses• Add BIP38 support• Allow initial number of rows to be set by the user• Raw entropy shows groupings with space every 11 bits• Checksum shown in entropy details• Warn that entropy values should exclude checksum• Warn when generating low entropy mnemonics• Warn when overriding weak entropy with a strong mnemonic length• Fix missing span closing tag• Allow xpub to be used as root key for segwit derivations• Add visual privacy safeguard• Remove bip39-standalone.html from repository• Remove duplicate id properties on html elementsFeatures• Support for Groestlwallet (Use path m/0'/0)• Support for MultiGroestl HD (Use path m/0'/0)• Support for Simple Groestlcoin (Use path m/0'/0)• Support for Groestlcoinomi (Use path m/44'/17'/0'/0)• Support for Coinomi (Use path m/44'/17'/0'/0)• Support for Groestlpay (use path m/44'/0'/0'/0)• Support for Groestlcoin Samourai (use path m/44'/0'/0'/0 and enter BIP39 Passphrase)• Support for GRS Mainnet and GRS Testnet• You can enter an existing BIP39 recovery phrase, or generate a new random one (typing your own twelve words will probably not work how you expect, since the words require a particular structure as the last word is a checksum)• Number of words support for: 3, 6, 9, 12, 15, 18, 21 and 24• BIP32 support• BIP44 supportLive version available at https://groestlcoin.org/bip39/ But it is recommended to download the BIP39 tool offline and run it on your pc.
