In an early day I have encountered so many issues with how to get the Private Key of a Bitcoin Address, but couldn’t find the exact solution that I was looking for. After performing several research and hassle I could find the answer that I wanted. In the following article I will discuss the topic in detail to simplify the process for you.
Step-by-step Guide to how to get the Private Key of a Bitcoin Address:
Bitcoin’s Keys and Addresses
Public and private keys are some of the most important concepts in Bitcoin. Bitcoin is a complex system that produces these keys to the next level.
Private Keys
The private key is random number at the heart of bitcoin security. It is this key that gives a user control over all funds associated with a specific bitcoin address. The private key performs an important role, making it possible to produce vital signatures for spending bitcoins thus signifying ownership of transaction amount involved. Care should be taken to ensure that the private key does not come into contact with others since allowing it fall into unauthorized hands would result in loss of funds protected by this particular key. Furthermore, it’s crucial to keep copies and secure it from accidental disappearance, since once lost, all money connected to it can never be retrieved.
Insight: The private key for Bitcoin is simply a number. Interestingly, you can make such a private using simple things like a coin, pencil and paper; flip 256 coins one after another and you will have binary digits for your random secret numbers which could then be used as a basis for creating your personal bitcoin wallet From here, the public Key may be derived from the private key
Generating a Private Key from a Random Number
The first step in key generation is to obtain secure entropy or randomness. Generating a Bitcoin key involves the simple task of “Picking a number between 1 and 2^256”. The method by which this number is selected can be any, provided that it is not predictable or repetitive. Bitcoin software uses built-in OS random number generators to generate 256 bits of entropy (randomness). Normally, initializing the OS random number generator requires some form of human intervention to provide a source of randomness such as moving the mouse for a few seconds.
The private key, to be precise, can take on any value between 0 and n – 1 whereby n is the constant (n = 1.1578 * 10^77, slightly less than 2^256) defined as the order of the elliptic curve in use by Bitcoin. Such a key is created by picking up a random number of up to 256 bits which is verified to be lower than n. In programming terms, this usually involves supplying an input that has more random numbers derived from a cryptographically secure source of randomness into the SHA256 hash algorithm which takes only 256 bits at a time. If it is below n, then it means there exists a suitable private key. Otherwise, another random number must be tried once again.
NB: It is important not developing your own code for generating random numbers or employing “simple” random number generator provided by your programming language. Instead make use of Cryptographically Secure Pseudo Random Number Generator (CSPRNG) with seed taken from a high quality entropy source. It is very essential that you carefully review the chosen random number generation library’s documentation so as to ascertain its cryptographic security level. The implementation of CSPRNG should be correct if we need to keep our keys safe enough.
Here is a randomly generated private key (k) and given as hexadecimal. It contains 256 bits represented by 64 hexadecimal digits, with each digit recording 4 bits.

Analysis:
The size of Bitcoin’s private key space (2^256) is an astronomical number, about 10^77 as a decimal. For comparison, there are an estimated 10^80 atoms in the observable universe.
The `getnewaddress` command is used to generate a new key using the Bitcoin Core client. For security reasons, it displays only the address, not the private key. The `dumpprivkey` command is used to retrieve the private key. This command prints the private key in a Base58 checksum-encoded format called Wallet Import Format (WIF), which will be further examined in Private key formats Below is an example of using these two commands to generate a private key and they are expressed.

The `dumpprivkey` command retrieves the private key generated by the `getnewaddress` command from the wallet. It is important to note that Bitcoin cannot determine the private key of an address unless both are stored in the wallet.
Caution: The `dumpprivkey` command does not generate a private key from the address, as this is not possible. Instead, it only displays the private key already known by the wallet generated by the `getnewaddress` command.

Remember, it is impossible to obtain the private key of any Bitcoin address unless you are the owner of that address. A private key is a set of private information used to access and manage funds associated with a Bitcoin address. It is important to keep the private key safe and not share it with anyone. If you have lost your private key, it is unlikely that you will be able to recover the funds associated with that address.
Private keys can also be generated and displayed using the Bitcoin Explorer command-line tool using commands such as `seed`, `ec-new`, and `ec-to-wif`:
How do I get my private key on a physical bitcoin?
