In this post, we will be addressing one of the most important questions that every Crypto enthusiast or investor will have to ask themselves at some point, and that question is ‘’What is a Private key’’?

What exactly is a Private Key

A private key in regards to ”Cryptography” is a set of alphanumeric phrase that is used to encrypt and decrypt specific data. Knowing the importance of a Private Key is an integral aspect of Bitcoin and essentially every other Blockchain-based digital currency.

For those new to the Cryptospace, a Private key for electronic/digitally encrypted information is really just bits of code that use an algorithm to lock and unlock information. A Bitcoin private key can be represented in one of several ways, but it’s common to see a randomized combination of Upper/Lowercase Alphabets and numbers.

An example would be a Bitcoin Private Key; A7SgtZFTzasR9dkTt9PbW8a8hWu8Ap3ErBn7zBkuLf386nXTCicp

Every Bitcoin wallet contains one or more private keys, which are mathematically generated and meant to be saved in the wallet file of the person who owns the balance. Theoretically speaking, it’s impossible to reverse engineer and reach the private key from which it was generated as the odds are against it. All private keys are mathematically related to all Bitcoin addresses that are randomly generated by a third-party wallet service provider since there can be only 1 Private key linked to a specific Bitcoin Address

Importance of a Cryptic Private Key

If you want to move Cryptocurrency from a wallet, you’ll be required to know the Private key in order to be authorized to transfer digital assets from one address to another. When dealing with a distributed ledger, a Private key is used to sign a transaction when transferring digital currencies, this means that you’ll need a private key to prove that you’re allowed to send Bitcoin to a different address

Without a private key, you’re not entitled to move any Bitcoin hence you’ll no longer have control over the funds. Not having any power to trade nor transfer Bitcoin as the result of non-authorized access means you’ll most likely never be able to retrieve lost funds. Centralized Exchanges like Bittrex, Coinbase or Binance have full control over the Cryptocurrencies that are stored via the integrated wallet, these services do not share out sensitive information like private key. When an online Bitcoin wallet provider does not generate or reveal a set of private key, you can assume that the service is fully responsible of managing clients digital assets.

What is the difference between a Public and Private key

The Public and Private key pair are comprised of two uniquely related cryptographic keys (consists of long random numbers). The Public Key is what its name suggests is Public whereas a Private key is meant to remain confidential to the respective owner.

A Private key is usually the longer of the two, and are used to generate a signature for each transaction done via the Blockchain. The other way to differentiate these two is by the technology behind each of these keys. Whereby the public key is used by one party to perform encryption and is not the same as a private key which is used in decryption. Each user will have both a public and a private key, the public encryption key and a private decryption key. As for the Public key, it is meant to be shared as it’s a public address just like how you would give out an email address to receive email, a wallet address should be given out to receive payments.

And a private key is basically like a password for your email address so that you can access and send a message from that particular email address and view your messages, wallets have private keys that are needed to send funds from a wallet to any other address or approve of a transaction out from the user’s wallet.

Summary

If you don’t own or know the set of private key of your Cryptocurrency address, you’re not in control of your funds

Unfortunately, if a Private key ends up forgotten or non-retrievable the end result will be you losing direct access to any digital assets stored on the Blockchain because you’re unable to access funds using a Crypto wallet client without the private key. If you don’t have a private key, you cannot transfer or retrieve any Cryptocurrency stored on the blockchain network as it’s set to remain locked up until the exact private key grants your authorization to sign signatures
