Bitcoin Private Keys

Do you have any idea what bitcoin is? Bitcoin is best known as an electronic cash system, but all is an Internet-based encrypted communications system behind it. Rather than transmitting emails, texts, or web pages, the Bitcoin network conducts transactions, which are value-transfer communications.

Bitcoin users are familiar with seeing alphanumeric sequences of data on the blockchain regularly. For example, these strings comprise public addresses and hashes, but where are private keys.

In the same way, anybody may know your house/flat number; anyone in the Bitcoin world can give you bitcoins if they know your public address (Bitcoin address). And you’ll need your private key to unlock those bitcoins, which you’ll have to take full responsibility for, much like the keys to your mailbox.

More critically, what are these private keys that many professionals discuss but cannot see? A Bitcoin private key is, at its base, a number. That is an address utilized to sign a transaction that is associated with the public address. However, this is merely the top of this cryptographic iceberg.

It’s crucial to understand what a bitcoin private key is since it ensures your Bitcoins are only yours. Let’s take a closer look at Bitcoin private keys and learn all we need to know.

What Is A Bitcoin Private Key?

A private Bitcoin key is a unique number that allows users to utilize their Bitcoins or control them. It has save inside the wallet of your Bitcoin. You should expect this to see if you would see a Bitcoin private key list on your screen; it consists of:

  • A hexadecimal 256-bit number
  • It signifies an alphanumeric string of 64 characters – a line of numbers and letters;
  • The figures on this string range from 0 to 9; letters vary between A and F –hexadecimal. Therefore a number is based on ten digits and the first six letters of the English alphabet.

However, a private key is like your CVC, while a public address is like your credit card number. You know, the 3-digit secret behind a card?

When you have a bitcoin wallet, a private address establishes by random means. Due to the advanced encryption method, we apply the possibility to create two identical private keys.

How to Find A Bitcoin Private Key?

A private key can be found in WIF (Wallet Import/Export Format) and a compressed key. It is uncomfortable to use such a long chain of code; thus, a private key often provides in the WIF (Wallet Import Format). This version is reduced, with 51 characters in length only (0-9 characters and A-F) and 5. It is a short version.

Do you know what does a bitcoin private key looks like?

Here is a WIF sample of Bitcoin’s private key:


The WIF’s overall BTC private key version offers certain benefits. It’s shorter and more convenient to use, as we have mentioned. It also includes unique code bits that serve the purpose of checking and automatically correcting the type address.

Private Keys Encryption

It is an encrypted version of a private key if it looks like WIF but starts from 6. To guarantee an additional protective layer, people encrypt keys. We use a different technique to produce such a string of code. To decode (decode) the key, we must input the password we established to encrypt.

Public and Private Keys

A bitcoin wallet comprises a group of key couples, each with a private and a private key. A public key use to verify that you are the owner of the digital wallet and that you have permission to accept funds from it.

The final hash of your public key is your wallet address, which is 256 bits long. As the name indicates, a public key is information that is generally known and used for identification purposes.

Your private key is something entirely different. You have only access to the private key, enabling you to use the funds in any way you think fits in your digital wallet. Your digital wallet will automatically produce a private key on your behalf, used to sign each transaction.

To summarize, a public key is a code that identifies your digital wallet and allows you to receive funds from it. A private key is needed to confirm transactions, letting you use the bitcoin saved in your digital wallet.

How to Use Bitcoin, Private Key?

Irreversible transactions require private keys. Yes, it’s unavoidable! They let you spend and send bitcoins to anybody, anywhere. When we utilize the private keys to transmit bitcoins, mathematical signatures are attached to each transaction, ensuring that the transaction is irreversible.

These signatures are unique for each transaction, even though they produce using the same private keys. They can’t copy because of this characteristic. The user can confidently frequently utilize the same private key.

For A Transaction, Using Private and Public Keys

Assume you’re transferring 1 BTC to your friend. You make a transaction where you identify yourself as the sender and your friend as the recipient of the funds. After that, you’ll broadcast the transaction to alert the Bitcoin network.

  • Choose a private key first. You generate a public key from it using a unique encryption method. You’re supposed to provide your friend this public key.
  • You compose a message for Bill and digitally sign it. You get it by running your private key through a specific encryption algorithm and attaching the resultant code to the message. Every signature is unique, and you may make an unlimited number of them with the same private address.
  • Your friend takes your message, public key, and signature and processes them using a signature algorithm. The algorithm returns okay if it’s the message you submitted.

Why do we need to have a digital signature? There are three factors at play. It first informs the receiver that the communication is from a known sender. Second, a digital signature eliminates the sender’s ability to deny sending the communication. Third, it ensures that the communication has not been interfered with while in route.

A digital signature, unlike a traditional signature, cannot be falsified. You’ll need a secret private key to make it.

Where to Store Private Keys?

These cryptographic keys are essential for bitcoin ownership. These keys produce and are held by the file/software, not on the Bitcoin network. These keep in a wallet. There are many different forms of wallet, some of which allow the user to store their private keys and secure them.

On behalf of the user, some maintain the key security. I’ve looked into each sort of safety precaution for you so you can pick the most appropriate wallet for your needs.

  • Mobile Wallets

Some allow you to preserve and secure your private key. In contrast, others do it automatically by employing different security methods such as two-factor authentication or encryption. It’s important to note that no one is accountable for it and if the service hack, your bitcoins will go away.

Android Wallets:

  • Trust Wallet
  • SamouraiWallet
  • Guarda
  • Atomic Wallet

IOS Wallets:

  • Trust Wallet
  • Muun Wallet
  • Desktop Wallets

Desktop wallets are a viable alternative. You may download and import BTC public and private keys in the form of a file. With a strong password, you may safeguard this file and safely keep it on a hard drive. Don’t forget that this disc is safe storage too. To this end, for example, utilize a bank vault.

  • Paper Wallets

BTC private keys and public addresses print on these wallets, which are sheets of paper. Paper wallets may appear plain and uninteresting, but they are a secure way to keep your BTC-related sensitive data.

The primary reason is that they are not linked to the internet, making them inaccessible to virus assaults. This format is also resistant to a variety of problems that might occur with electrical equipment. A specific online service, such as Wallet Generator, is used to produce a paper wallet.

Such wallets refer to ‘cold storage’ since the keys are produced offline and never kept on a computer or internet. You can use, which is a particular HTML website, to do this. You can build your wallet.

You may store the HTML page offline, and bitcoin private keys generated can be unplugged from the internet. You may print it on paper, keep it on a USB or hard disc as a soft copy.

  • Hardware Wallets

The most secure wallets are hardware wallets. They’re tiny USB devices meant to keep your cash and all private keys safe and protected from watchful eyes. Hardware wallets are impossible to hack because of this.

You can retrieve your BTC and private keys if you lose, damage, or destroy such a device by utilizing a backup phrase. Tresor and Ledger Nano S are the most popular hardware wallet types, and they handle a variety of popular coins.

  • Trezor

Trezor was the first hardware wallet since Bitcoin’s creation. It’s a tiny gadget that plugs into your computer through the USB connection. Its primary function is to store and sign transactions using private keys that keep offline.

  • Ledger Nano S

Ledger Nano S can even utilize on a malware-infected PC. It features two buttons that must push together to sign and approve a transaction, making it difficult to use by a hacker.

The user must additionally establish a PIN code while setting up the Ledger Nano S. If your Nano S is misplaced, the PIN code protects your bitcoins

Why Am I Unable To See My Private Key, But I Am Still Able To Use It?

Even if you conduct millions of transactions, you may never see one because of the nature and sensitivity of Bitcoin private keys. But how is this even feasible if you can sign a transaction using the private key?

The best explanation is that BIP32 and BIP39 – BIP stands for Bitcoin Improvement Proposal – are responsible for most wallets we use today.

  • Using elliptic curve mathematics, which allows computers to produce public keys without disclosing secret ones, BIP32 allows a wallet to generate multiple public addresses and matching private keys without the need for regular backups
  • BIP39 enables a wallet to generate multiple public addresses and private keys based on a seed.

It implies that if you can see your 12- or 24-word seed, you’re looking at your private keys’ source. As a result, keep these seeds in a secure location away from public scrutiny.

Why Is It Crucial To Keep Your Private Key Secret?

Anyone who has private key access can take your money at any time. Suppose your evil coworker obtains your private key (due to you leaving your paper wallet on your desk). In that case, they can make a digital signature with it.

They can then use that signature to sign a network transaction that looks exactly like yours. For example, they can transmit all of your cryptocurrency to a different address. You’ll never be able to undo this transaction, and you’re not going to know they did it.

It is the most acceptable thing if you take exceptional care of your private keys. Please do not send it to anybody via a chat, email, or social media channel. Do not share your private key pictures. Never store a Google Doc private key.

Please be aware that specific desktop wallet programs keep your private key in your hard disc in a usual location. This location is a hacker’s honeypot who knows that you are a crisis user. That is why up-to-date anti-virus software on your device is so vital.

You can also encrypt this wallet file to protect it from viruses. This feature is available in many wallet applications. To decrypt the private key, you will need to create a password, which the hacker will have to crack. It will be a very tough and time-consuming process if the password is quite strong.

What Happens If Your Bitcoin Wallet Keys Are Lost Or Forgotten?

The public and private keys, as already established, function as a kind of identity. You should thus be careful, and this data should be protected.

One of the first is having an encrypted key but forgetting the password. The data will only decrypt when the correct password has been enter. It isn’t much you can do if you don’t know the password set during the encryption procedure.

Your private key should treat as if it were a genuine banknote. If you lose it, you can never get it back. You won’t be able to conduct transactions, buy things, or transfer money to friends.

A missing private key will deactivate any transactions associated with it. It is thus an excellent idea to memorize a private key. This type of information should never be stored address online since it can be a hack. Another wise suggestion is to use a hardware bitcoin wallet to keep your money safe and secure without the danger of its loss forever.


Bitcoin may be considered a public key cryptography-protected open communications system. In contrast, Bitcoin is secure by digital message signatures with a unique private key compatible with other systems protected by a username and password logins.

This single access point prioritizes safe, private key bitcoin creation, usage, and storage.
