There is more to a bitcoin wallet than just the address itself. It also contains the public and private key for each of your bitcoin addresses. Your bitcoin private key is a randomly generated string (numbers and letters), allowing bitcoins to be spent. A private key is always mathematically related to the bitcoin wallet address, but is impossible to reverse engineer thanks to a strong encryption code base.

If you don’t back up your private key and you lose it, you can no longer access your bitcoin wallet to spend funds.

As mentioned, there is also a public key. This causes some confusion, as some people assume that a bitcoin wallet address and the public key are the same. That is not the case, but they are mathematically related. A bitcoin wallet address is a hashed version of your public key.

In cryptocurrencies, a private key allows a user to gain access to their wallet. The person who holds the private key fully controls the coins in that wallet. For this reason, you should keep it secret. And if you really want to generate the key yourself, it makes sense to generate it in a secure way. Anyone Who Knows Your Private Key Can Steal Your Funds. Any valid transaction bearing a valid signature will be accepted by the Bitcoin network. At the same time, any person in possession of a private key can sign a transaction. These two facts taken together mean that someone knowing only your private key can steal from you. In your function generateprivatekeywif, you never use hashed, you re-compute it for the return value. In a nice self-contained module like this one, you should definitely add docstrings to your functions. Have a look at PEP257 to see how they are defined. You currently do from ecdsa.keys import SigningKey, but never use it. Since anybody who knows the key can spend the funds, the key must be kept absolutely secret. The key also needs to be kept safe, since losing the key would make spending the funds impossible. Generating a private key is easy - just pick any random number between 1 and 61494337. Word generation series1-assessement answer key. Feb 12, 2015  A private key is just a number picked at random. The private key is used to generate the public key through an irreversible process. In the case of Bitcoin the Private key is turned into the Public key through Elliptic Curve Cryptography or ECC for short.

Every public key is 256 bits long — sorry, this is mathematical stuff — and the final hash (your wallet address) is 160 bits long. The public key is used to ensure you are the owner of an address that can receive funds. The public key is also mathematically derived from your private key, but using reverse mathematics to derive the private key would take the world’s most powerful supercomputer many trillion years to crack.

Besides these key pairs and a bitcoin wallet address, your bitcoin wallet also stores a separate log of all of your incoming and outgoing transactions. Every transaction linked to your address will be stored by the bitcoin wallet to give users an overview of their spending and receiving habits.

Feb 12, 2015  How to create a Bitcoin address from a Public Key? As seen in our guides to elliptic curve cryptography and how to create a Bitcoin Private key – a public key is in fact just coordinates on the Bitcoin curve calculated through multiplying the generator point by the private key number. Where Can I Find My Bitcoin Private Key? However, first of all, you will need to set up a Bitcoin wallet which will then randomly generate a 256 bit long number. This will be your private key. These two factors mean that if someone knows your private key, it may be possible to steal funds from you.

Last but not least, a bitcoin wallet also stores your user preferences. However, these preferences depend on which wallet type you’re using and on which platform. The Bitcoin Core client, for example, has very few preferences to tinker around with, making it less confusing for novice users to get the hang of it.

Your bitcoin wallet generates a “master” file where all of the preceding details are saved. For computer users, that file is called wallet.dat. It’s saved on a Windows machine, for example, in the C:UserYournameDocumentsAppDataRoamingBitcoinfolder. Make sure to create one or multiple backups of this wallet.dat file on other storage devices, such as a USB stick or memory card. The bitcoin wallet software will let you import a wallet.dat file in case your previous file is damaged or lost, restoring your previous settings, including any funds associated with your bitcoin wallet address.
