Generate Private Keys From Ledger Seed

 
An example paper printable bitcoin wallet consisting of one bitcoin address for receiving and the corresponding private key for spending.

With HD wallets, a single key can be used to generate an entire tree of key pairs. This single key serves as the 'root' of the tree. The word seed is simply a more human-readable way of expressing the key used as the root, as it can be algorithmically converted into the root private key.

My recovery phrase: This. Aug 11, 2019  But despite all these facts, many newbie investors deal with their private keys or seed keys in a very careless manner and hence jeopardize the security of their funds. Therefore I thought it was important to share ‘where you should store your private keys’. Best Tips For Storing Your Private Keys. Oct 06, 2017  You can recover your keys without a Ledger Nano S This video shows how you get the public and private key of Bitcoin and Ethereum from your leder 24 words recovery phrase. My recovery phrase: This. A cryptocurrency wallet is a device, physical medium, program or a service which stores the public and/or private keys and can be used to track ownership, receive or spend cryptocurrencies. The cryptocurrency itself is not in the wallet. In the case of Bitcoin and cryptocurrencies derived from it, the cryptocurrency is decentrally stored and maintained in a publicly available ledger called the. It's a very simple command-line tool that can generate accounts for a given mnemonic seed. However, the whole point of the Ledger is to not use the keys outside the device because it's much easier for hackers to steal your funds. The low level method of generating the keys from mnemonic seed is described in SEP-0005. I followed the faq in ledger nano s. This says that I can retrieve the private and public key. Does it mean that using the 24 word seed we can generate the same set of private and public keys in same order as it was created in my ledger nano s?

A cryptocurrency wallet is a device,[1] physical medium,[2] program or a service which stores the public and/or private keys and can be used to track ownership, receive or spend cryptocurrencies.[3] The cryptocurrency itself is not in the wallet. In the case of Bitcoin and cryptocurrencies derived from it, the cryptocurrency is decentrally stored and maintained in a publicly available ledger called the blockchain.[3]

Functionality

A cryptocurrency wallet, comparable to a bank account, contains a pair of public and private cryptographic keys. A public key allows for other wallets to make payments to the wallet's address, whereas a private key enables the spending of cryptocurrency from that address.[4]

Wallet types

Wallets can either be digital apps or be hardware based.[5] They either store the private key with the user, or the private key is stored remotely and transactions are authorized by a third party.

An actual bitcoin transaction from a web based cryptocurrency exchange to a hardware wallet (a Ledger Nano S).

Multisignature wallet

Multisignature wallets require multiple parties to sign a transaction for any digital money can be spent.[6] Multisignature wallets are designed to have increased security.[7]

Key derivation

Deterministic wallet

With a deterministic wallet a single key can be used to generate an entire tree of key pairs.[8] This single key serves as the root of the tree. The generated mnemonic sentence or word seed is simply a more human-readable way of expressing the key used as the root, as it can be algorithmically converted into the root private key. Those words, in that order, will always generate exactly the same root key. A word phrase could consist of 24 words like: begin friend black earth beauty praise pride refuse horror believe relief gospel end destroy champion build better awesome. That single root key is not replacing all other private keys, but rather is being used to generate them. All the addresses still have different private keys, but they can all be restored by that single root key.The private keys to every address it has and will ever give out can be recalculated given the root key. That root key, in turn, can be recalculated by feeding in the word seed. The mnemonic sentence is the backup of the wallet. If a wallet supports the same (mnemonic sentence) technique, then the backup can also be restored on another software or hardware wallet.

A mnemonic sentence is considered secure. The BIP-39 standard creates a 512-bit seed from any given mnemonic. The set of possible wallets is 2512. Every passphrase leads to a valid wallet. If the wallet was not previously used it will be empty.[3]:104

Non-deterministic wallet

Seed

Generate Private Keys From Ledger Seed Online

In a non-deterministic wallet, each key is randomly generated on its own accord, and they are not seeded from a common key. Therefore, any backups of the wallet must store each and every single private key used as an address, as well as a buffer of 100 or so future keys that may have already been given out as addresses but not received payments yet.[3]:94
