BIP39 Mnemonic. The BIP39 mnemonic seed phrase plus the word “mnemonic” plus an optional passphrase created by the user are all input into a Key Stretching Function called PBKDF2 using HMAC-SHA512. PBKDF2 is a useful function allowing to derive a low-entropy password into a larger cryptographic key. Each word is 11 bits (2^11 = 2048 possible words).

Next, use the Ledger to create a temporary passphrase-protected wallet, and get its address. Infact if no passphrase is specified, the system takes the constant word “mnemonic” as a salt when producing a 512bits seed. Unlike the single duress PIN, an unlimited number of related wallets can be created using BIP39. It allows for a standardized way of displaying your private keys since, instead of having a string of random letters and numbers, you have a sequence of English words, selected from 2048 possible words, that your wallet displays for you to record with a pen and paper. This is optional and this feature improves the security and flexibility. Coin. It involved bruteforcing a 12-word Bitcoin seed passphrase by starting off with partial information about it. As a result, some wallets such as Ledger use a 24-word passphrase. Ledger is compatible with Windows, Mac, Linux, and Chrome OS. BIP39 Passphrase Support: Whether the device supports adding a BIP39 passphrase to your seed phrase in order to increase security of the device as well as secure your offline seed phrase backup. seed words and a passphrase. BIP39 is a protocol that describes how to create a human readable mnemonic sentence and how to convert that mnemonic into a seed that can then produce … Ledger's approach takes the assumption that the host computer should never be relied and input and display should always be carried out on the Ledger device. On-Device BIP39 Passphrase Entry : Whether the user can enter the BIP39 passphrase without needing to use an external PC or device. Reset the Ledger S Nano wallet device. Restore the reset device to the seed and passphrase you recorded. Based on Trezor’s tweet, it will be very difficult for the attackers to infiltrate the system remotely. 5. The lack of entropy is balanced by a CPU intensive derivation function preventing brute-force. BIP39 explains a recommended way to create a seed from a mnemonic. BIP39 Passphrase. The Ledger Nano S allows you to backup your hardware wallet using a standard known as BIP39, in short, your private key is converted into an easily readable series of 24 words. Place the passphrase into a tokens.txt file along with one or two other words (just so btcrecover has something to test), and then run this from the command line … I have the bitcoin and ethereum public addresses for this mnemonic. Just note that this is different from your wallet password or PIN. Usage/option of BIP39 passphrase(s) is very important for me, as it provides any amount of different wallets depending on the passphrase entered, thus providing as many levels of plausible deniability as you wish.

If your passphrase is a 1 word from a dictionary (aka the 25th word) it is NOT SAFE. Electrum, on the other hand, uses BIP32. For example, the Ledger Nano S hardware wallets support SEED BIP39 and 44, idem Trezor. Change it to at least a 4 word passphrase as soon as possible; lonelypumpkins is a better passphrase than hodl but it’s not a passphrase than can withstand a few hours of cracking on regular hardware (too short) BIP39 is the conventional means of generating deterministic keys in the crypto space. Thotheolh Tay on BIP39 passphrase for seed. The functionality includes additional passphrase protection string (up to 100 chars - just like Ledger) and ability to generate HD accounts based on account index you enter. Since both the Trezor Model T and Ledger Nano X use BIP-39 for the seed and both support passphrases, I figured I could just restore the same BIP-39 seed and use the same passphrase on the Ledger Nano X as I used on the Trezor and it would restore all the same wallets. Hi, Here is my issue: I have a 24 word seed that is perfectly fine. DO NOT USE THESE EXCEPT FOR TESTING. Mnemonic code for generating deterministic keys. 7. 4. Most wallets in the crypto space, including Keepkey, Ledger, and Trezor, and other hierarchical deterministic (HD) wallets, leverage BIP39 to automatically generate seed keys. This feature is supported by all hardware wallets like Ledger, Trezor, Keepkey etc. As an added advantage, Trezor uses BIP39 and BIP44 standards for creating new wallets, so the generated 24-word seed and passphrase can be used by other compatible wallets to recover the wallet in case of theft or damage of the device. Path Address Private Key; Examples.
