These keys are compormised now. A bitcoin wallet contains a collection of key pairs, each consisting of a private key and a public key. The private key k is a number, usually picked at random. From the private key, we use elliptic curve multiplication, a one-way cryptographic function, to generate a public key K.
From the public key K , we use a one-way cryptographic hash function to generate a bitcoin address A. In this section we will start with generating the private key, look at the elliptic curve math that is used to turn that into a public key, and finally, generate a bitcoin address from the public key. A private key is simply a number, picked at random.
Ownership and control over the private key is the root of user control over all funds associated with the corresponding bitcoin address. The private key is used to create signatures that are required to spend bitcoins by proving ownership of funds used in a transaction. The private key must remain secret at all times, as revealing it to a third party is equivalent to giving them control over the bitcoins secured by that key.
The private key must also be backed up and protected from accidental loss, since if lost it cannot be recovered and the funds secured by it are forever lost too. The first and most important step in generating keys is to find a secure source of entropy, or randomness.
The exact method you use to pick that number does not matter as long as it Is not predictable or repeatable. Usually, the OS random number generator is initialized by a human source of randomness, which is why you may be asked to wiggle your mouse around for a few seconds. For the truly paranoid, nothing beats dice, pencil and paper. All Bitcoin private keys is simply an integer between number 1 and or HEX: from 1 to 0xfffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd We just generate a range of these integers in sequence, divide into pages and show on each page.
All private keys. Do not overestimate your ability to remember passphrases especially when you may not use it very often. Warning : The seed phrase password should not be confused with the password used to encrypt the wallet file on disk. This is probably why many wallets call it an extension word instead of a password. Most people write down phrases on paper but they can be stored in many other ways such as memorizing , engraving or stamping on metal, writing in the margins of a book, chiselling into a stone tablet or any other creative and inventive way.
In the past many people have accidentally lost bitcoins because of failed backups, mistyped letters, forgotten hard drives, or corrupted SSD devices. It could be a good idea to write some words of explanation on the same paper as the seed phrase. If storing for the long term you may forget what a phrase is how it should be treated. A sample explanation that can be adapted is:. Through bitter experience it has been found that one of the most practical storage mediums is pencil and paper.
The private keys of a bitcoin wallet are encoded into random words from a dictionary which can be written down. If your hard drive crashes, you can find the paper with the seed phrase and restore the entire wallet. As seed phrases use natural language words, they have good error correction.
If one or two letters are missing the word can often still be deduced. For storing on paper writing with pencil is much better than pen [4] [5]. Paper should be acid-free or archival paper, and stored in the dark avoiding extremes of heat and moisture [6] [7] [8]. Seed phrases can also be stamped or engraved into metal which is significantly more durable than paper.
Metal backups are recommended if the threat model involves fire, water, extremes of temperature or physical stress. Some methods that are not recommended are: storing in a file on a computer including online , or storing online. Some people get the idea to split up their phrases, like storing 6 words in one location and the other 6 words in another location. This is a bad idea and should not be done, because if one set of 6 words is discovered then it becomes far easier to brute-force the rest of the phrase.
Storing bitcoins in multiple locations like this should be done with multi-signature wallets instead. The Shamir Secret Sharing algorithm is sometimes promoted as a way to divide control of bitcoins, but in practice there are many pitfalls and trade-offs that make it not worth it. Another bad idea is to add random decoy words that are somehow meaningful to you and later remove them to be left with only the word phrase. The phrase words come from a known dictionary see next section , so anybody can use that dictionary to weed out the decoy words.
This should probably only be done in situations that really need it, such as crossing a hostile border where one expects to be searched. Generally, a seed phrase only works with the same wallet software that created it. The BIP39 English word list has each word being uniquely identified by the first four letters, which can be useful when space to write them is scarce.
Seed phrases are sometimes called mnemonic phrases , especially in older literature. This is a bad name because the word "mnemonic" implies that the phrase should be memorized. It is less misleading to call them seed phrases. An especially interesting aspect in the power of paper backups is allowing your money to be two places at once.
At the London Inside Bitcoin conference, the keynote speaker showed 25 paper backups they were carrying—all password-protected. That is powerful. Jump to: navigation , search. Category : Technical.

For the truly paranoid, nothing beats dice, pencil and paper. A seed phrase , seed recovery phrase or backup seed phrase is a list of words which store all the information needed to recover Bitcoin funds on-chain.
Wallet software will typically generate a seed phrase and instruct the user to write it down on paper. Anybody else who discovers the phrase can steal the bitcoins, so it must be kept safe like jewels or cash. For example, it must not be typed into any website. Seed phrases are an excellent way of backing up and storing bitcoins , so they are used by almost all well-regarded wallets. Seed phrases can only backups funds on the block chain. They cannot store funds involved in off-chain transactions such as Lightning Network or Blinded bearer certificates.
Although these technologies are in their infancy as of so its possible in future seed phrases could be used to backup them. BIP39 is the most common standard used for seed phrases. One notable example is Electrum wallet , which is using its own standard, and for good reasons. BIP39 has some flaws, known in the technical community but not known much wider. They are described here on this electrum doc page. Most seriously, BIP39 flaws mean it is not true to say that backing up a BIP39 seed phrase and name of wallet software is the only thing a user needs to do to keep their money safe.
BIP39 works this way because its designers wanted their hardware wallet to also support altcoins. A simplified explanation of how seed phrases work is that the wallet software has a list of words taken from a dictionary, with each word assigned to a number.
The seed phrase can be converted to a number which is used as the seed integer to a deterministic wallet that generates all the key pairs used in the wallet. However, some of the data in a BIP39 phrase is not random, [2] so the actual security of a word BIP39 seed phrase is only bits. This is approximately the same strength as all Bitcoin private keys, so most experts consider it to be sufficiently secure. It is not safe to invent your own seed phrase because humans are bad at generating randomness.
The best way is to allow the wallet software to generate a phrase which you write down. As seed phrases use natural language words, they have excellent error correction. Words written in bad handwriting can often still be read. If one or two letters are missing or unreadable the word can often still be deduced.
The word list that the seed phrase words are drawn from is carefully chosen so that the first four letters of each word are enough to uniquely identify it. This compares well with writing down a raw private key where a single letter being unreadable or incorrect can make the private key useless depending on the serialization format. Seed phrases, like all backups, can store any amount of bitcoins.
For this reason many wallets make it possible to encrypt a seed phrase with a password. The password can be used to create a two-factor seed phrase where both "something you have" plus "something you know" is required to unlock the bitcoins. This works by the wallet creating a seed phrase and asking the user for a password. Then both the seed phrase and extra word are required to recover the wallet. The BIP39 standard defines a way of passphrase-protecting a seed phrase.
A similar scheme is also used in the Electrum standard. If a passphrase is not present, an empty string "" is used instead. Warning : Forgetting this password will result in the bitcoin wallet and any contained money being lost. Do not overestimate your ability to remember passphrases especially when you may not use it very often. Warning : The seed phrase password should not be confused with the password used to encrypt the wallet file on disk.
This is probably why many wallets call it an extension word instead of a password.
