# Mnemonic Code Converter

## Mnemonic

You can enter an existing BIP39 mnemonic, 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 (the last word is a checksum)

BIP32 Derivation Path

For more info see the BIP32 spec

BIP32 Derivation Path
Use hardened addresses
Hive Wallet

Use path `m/0'/0`. For more info see the Hive Wallet homepage

Mycelium Wallet

Use path `m/44'/0'/0'/0`. For more info see the Mycelium Wallet homepage

Bitcoin Core

Use path `m/0'/0'` with hardened addresses. For more info see the Bitcoin Core BIP32 implementation

Block Explorers

Use path `m/44'/0'/0'`. Only enter the `xpub` extended key into block explorer search fields, never the `xpriv` key.

BIP32 Extended Key
BIP32 Extended Key (addresses only)

## Derived Addresses

Note these addreses are derived from the BIP32 Extended Key

Path | Address | Public Key | Private Key

### Private Keys

Use private keys at brainwallet.org, but be careful - it can be easy to make mistakes if you don't know what you're doing

### Entropy

Entropy values must be sourced from a strong source of randomness. This means flipping a fair coin, rolling a fair dice, noise measurements etc. Do NOT use phrases from books, lyrics from songs, your birthday or steet address, keyboard mashing, or anything you think is random, because chances are overwhelming that it isn't random enough for the needs of this tool.

The random mnemonic generator on this page uses a cryptographically secure random number generator, and can generally be trusted more than your own intuition about randomness. If cryptographic randomness isn't available in your browser, this page will show a warning and will not generate random mnemonics.

You are not a good source of entropy.
