Btc import own private key

Paper wallets are an effective way of storing Bitcoin private keys offline. They protect the user against potential theft or mishap with the desktop or mobile devices. You can make your paper wallet from bitaddress. You can save the HTML page offline and remain disconnected from the internet to generate the keys. They can be printed on paper or stored as a soft copy on a USB or hard drive.

Read my previous guide on how to make a Bitcoin paper wallet. Bitcoin Paper Wallet Conclusion The most important thing in a Bitcoin wallet is your private key, which will prove that the bitcoins you claim are actually yours. How are you keeping your private keys safe? Let us know what you do in the comments below!! Have a question about Bitcoin Private keys? Feel free to ask in the comment section below. Here are a few more Bitcoin wallet-related guides that you must read next:.

It can be a binary string, Base64 string, a WIF key , mnemonic phrase , or finally, a hex string. For our purposes, we will use a 64 character long hex string. The same private key, written in different formats. Why exactly 32 bytes? Great question! More specifically, it uses one particular curve called secpk1. Now, this curve has an order of bits, takes bits as input, and outputs bit integers. And bits is exactly 32 bytes. So, to put it another way, we need 32 bytes of data to feed to this curve algorithm.

There is an additional requirement for the private key. Naive method So, how do we generate a byte integer? The first thing that comes to mind is to just use an RNG library in your language of choice. You see, normal RNG libraries are not intended for cryptography, as they are not very secure.

They generate numbers based on a seed, and by default, the seed is the current time. That way, if you know approximately when I generated the bits above, all you need to do is brute-force a few variants. When you generate a private key, you want to be extremely secure. Remember, if anyone learns the private key, they can easily steal all the coins from the corresponding wallet, and you have no chance of ever getting them back. This method is usually much more secure, because it draws entropy straight from the operating system.

The result of such RNG is much harder to reproduce. In Python, cryptographically strong RNG is implemented in the secrets module. But can we go deeper? Specialized sites There are sites that generate random numbers for you. We will consider just two here. One is random. Another one is bitaddress. Can random. Definitely, as they have service for generating random bytes. But two problems arise here. Can you be sure that it is indeed random?

The answer is up to you. Now, bitaddress. So how does it work? It uses you — yes, you — as a source of entropy. It asks you to move your mouse or press random keys. You do it long enough to make it infeasible to reproduce the results. The process of generation an entropy by randomly moving the mouse. The large chunk of symbols shows the pool. Are you interested to see how bitaddress. For educational purposes, we will look at its code and try to reproduce it in Python.

Quick note: bitaddress. For our purposes, we will make the algorithm return a hex string so that we can use it later for a public key generation. Bitaddress: the specifics Bitaddress creates the entropy in two forms: by mouse movement and by key pressure.

Bitaddress does three things. It initializes byte array, trying to get as much entropy as possible from your computer, it fills the array with the user input, and then it generates a private key. Bitaddress uses the byte array to store entropy. This array is rewritten in cycles, so when the array is filled for the first time, the pointer goes to zero, and the process of filling starts again.

The program initiates an array with bytes from window.

Wallets can import private keys via text files or QR code scanning. Instead, you need to start the bitcoind server. Close bitcoin-qt and start bitcoind -damon in Terminal Emulator. The version of bitcoind MUST be the same as bitcoin-qt! To enable it: Close Bitcoin-QT and restart it with bitcoin-qt -server. Unlock your wallet[ edit ] If you have an encrypted wallet recommended , you need to unlock it temporarily before importing private keys.

Typing this directly in a bash terminal will leave your wallet passphrase directly in the bash history but there are a couple of techniques you can use to avoid this. Import Private key s [ edit ] The last command unlocked your wallet temporarily for seconds, during which time you must import your private keys. For example, if you use a web wallet like Coinbase or Blockchain. Mobile and desktop wallets usually also generate a private key for you, although they might have the option to create a wallet from your own private key.

So why generate it anyway? Here are the reasons that I have: You want to make sure that no one knows the key You just want to learn more about cryptography and random number generation RNG What exactly is a private key? Formally, a private key for Bitcoin and many other cryptocurrencies is a series of 32 bytes. Now, there are many ways to record these bytes. It can be a binary string, Base64 string, a WIF key , mnemonic phrase , or finally, a hex string.

For our purposes, we will use a 64 character long hex string. The same private key, written in different formats. Why exactly 32 bytes? Great question!
