Questions tagged [mnemonic-seed]

A way of writing down a small set of dictionary words from which a seed-number can be recreated. This allows a wallet to be recreated from a saved phrase after the wallet has been lost or destroyed.

Mostly BIP39, an open standard for encoding a seed as a series of common words, but also collects other methodologies.

What's the relationship between SLIP39 and BIP39?

Trezor's SLIP39 makes it possible to apply Shamir's secret sharing to a Bitcoin wallet seed. How do SLIP39 and BIP39 relate to each other? I.e. it seems possible to derive SLIP39 from BIP39 words but this is messy, and deriving BIP39 from SLIP39 is…

Am I safe if 16 words in my 24 word seed are leaked?

I use a 24 word seed for my private key. I split the 24 words into 16 words in three pieces of paper, so one needs to have at least two pieces of paper to recover the wallet. However my question is, if someone gets one piece of paper, can they…

How to generate a valid hash for a bip39 seed phrase?

I'm trying to prove to myself that I understand how bip39 seed phrases work... I'm doing most of this in a spreadsheet because I thought it would be easier but I'm having trouble with the checksum value... These are the steps I'm taking: I start…

Are BIP39 mnemonics generated with a French list compatible with software that expects English words?

BIP39 specifies different word lists in different languages. But I wonder if the word list generated by a software that gives me French words (e.g. Copay on iOS) can be used to re-create the same wallet using another software that expects English…

Is mnemonic words -> mnemonic sentence standardized?

I was reading the BIP 39, and noticed that it does not refer to how the mnemonic sentence, used for seed calculation, is composed from mnemonic words. This is actually troublesome because in case of Japanese, the bip39 npm package joins the…

Is it safe to store a sha256 hash of my BIP39 seed on the blockchain?

According to https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki a 12 word BIP39 passphrase has entropy of 128 bits. My reason for doing so is that when I want check if I memorized my passphrase correctly, I could just check it against…

Use BIP39 to generate SSH or TLS keys?

Is it possible to use the same Bip39 mneumonic that generates addresses/keys to generate deterministic key pairs for use outside of cryptocurrency, say in ssh, tls, etc? I know that bip39 doesn't use RSA and some conversion would need to be done,…

Convert 12 word seed with passphrase -> 12 word seed without passphrase

Is it possible to derive a new 12 word seed from a 12 word seed with passphrase (13th word) such that they both produce the same master key?

Why Entropie is divided by 32 (Seed to MNEMONICS)

I want to create a Seed-Phrase (mnemonics) from entropy. One aspect of BIP39 is to create the checksum and describes it as follows (Link BIP39): The mnemonic must encode entropy in a multiple of 32 bits. With more entropy, security is improved…

Chance of a word repeating THREE times in a BIP39 Mnemonic passphrase? And what about 2 words repeating 2 times each?

So according to the other thread about BIP39 repeating words, the cahnce of a word repeating TWICE is 11.7%. Now I was wondering, since my passphrase may or may not contain THREE repetitions :O. And then just to finish the chance calculation wizards…

Why is "cancel canal can" an invalid BI39 (3 word) mnemonic phrase?

Is there an entropy rule that prevents this particular combination? e.g. it's not random enough? Or is this just a bug on this generator tool I'm using: https://iancoleman.io/bip39/#english

secret sharing scheme for 3-of-5 shares (for BIP39 mnemonic phrase of 24 words)

Given a 24 word BIP39 mnemonic phrase, I would like to have a way to split it into 5 shares, so that any 3 would allow me to reconstruct the phrase (but any less than 3 would not). This is easy enough to do with Shamir Secret Sharing, and very…

In the BIP39 specification, are seeds generated from encoded or decoded passphrase?

From the BIP39 spec: From mnemonic to seed A user may decide to protect their mnemonic with a passphrase. If a passphrase is not present, an empty string "" is used instead. To create a binary seed from the mnemonic, we use the PBKDF2 function with…
