Safely storing your Bitcoin is crucial. Unlike other forms of money that are controlled by banks and financial institutions, with Bitcoin and other cryptocurrencies you have many more alternatives on how to store and control your cryptocurrency securely.
When you think about it, when you own a cryptocurrency you actually only own a private key for that particular network. A private key is in effect a random set of characters that is used as information on the blockchain network to authorise transactions. So whoever has access to this information (private key) has access to your funds.

think of the entire blockchain as an apartment complex. The public keys in this analogy is the room numbers people may know what room number is yours they may have been there before and remember the address, you could have given someone the address, regardless of how they got it they know where to find you how to deliver things to your apartment but they cant physically enter or do anything within your apartment because they cant open the door. Only you have the key to your apartment and only you have control over the things inside it. If for whatever reason all your neighbors had a copy of your key you could keep no one out of your room and all of your possessions would be compromised. so in short people know your address (public key) and can send things to you but people don't have a key to your room(private key) where you store all of your possessions. Now this a simple explanation of how keys work and there are many different applications for using public and private keys and in all actually it isn't a key its a randomly generated number for your address in the blockchain which is nearly impossible to generate via key logging or other malicious attacks witch make it common practice among cryptos but in order for it to work only you must know your private keys because whoever owns the key to the door owns what's inside the apartment.

In fact, everything in blockchain-based digital finance offers a lot of texts that cryptocurrencies are hidden, and they show a high-protection base and put us to test with a certain algorithm, we share the information we provide with the world with one click, they are the money we sell them our life values. Therefore, all our data information, our wallet, etc. are under their protection and insecure.

What Is a Private Key?
A private key is a sophisticated form of cryptography that allows a user to access his or her cryptocurrency. A private key is an integral aspect of bitcoin and altcoins, and its security make up helps to protect a user from theft and unauthorized access to funds.
Understanding Private Key
When dealing with crypto currency, a user is usually given a public address and a private key to send and receive coins or tokens. The public address is where the funds are deposited and received. But even though a user has tokens deposited into his address, he won’t be able to withdraw them without the unique private key. The public key is created from the private key through a complicated mathematical algorithm. However, it is near impossible to reverse the process by generating a private key from a public key.
The private key can take a few different forms, usually depicted as a series of alphanumeric characters, which makes it hard for a hacker to crack. Most users represent their wallet keys in wallet import format, which has 51 characters. Think of a public address as a mailbox, and the private key as the key to the box. The mailman, and anyone really, can insert letters and small packages through the opening in the mailbox. However, the only person that can retrieve the contents of the mailbox is the one that has the unique key. It is, therefore, important to keep the key safe because if it is stolen or gotten without authorization, the mailbox can be compromised.
A digital wallet stores the private key of a user. When a transaction is initiated, the wallet software creates a digital signature by processing the transaction with the private key. This upholds a secure system since the only way to generate a valid signature for any given transaction is to use the private key. The signature is used to confirm that a transaction has come from a particular user, and ensures that the transaction cannot be changed once broadcasted. If the transaction gets altered, even slightly, the signature will change as well.
If a user loses his/her private key, s/he can no longer access the wallet to spend, withdraw, or transfer coins. It is, therefore, imperative to save the private key in a secure location. There are a number of ways that a digital wallet which contains a private key can be stored. Private keys can be stored on paper wallets which are documents that have been printed with the private key and QR code on them so that it can easily be scanned when a transaction needs to be signed.
The private keys can also be stored using a hardware wallet which uses smartcards or USB devices to generate and secure private keys offline. An offline software wallet could also be used to store private keys. This wallet has an offline partition for private keys and an online division which has the public keys stored. With an offline software wallet, a new transaction is moved offline to be signed digitally and then moved back online to be broadcasted to the cryptocurrency network.
These types of storage mentioned above are called cold storage, as private keys are stored offline. The other type of wallet, hot wallet, stores private keys on devices or systems that are connected to the internet. Examples of these wallets include desktop wallets (e.g., Electrum), mobile wallets (e.g., Breadwallet), and web-based wallets (e.g., Coinbase).

private key, which gives you access to your funds and is used to sign off for a transaction. Always make sure to keep your private key safe and secure, as if you will lose access to it, or simply forget it, you will not be able to access your finds. Similarly, if anyone gets hold of your private key, all the funds in your wallet will be stolen.

A private key, also known as a secret key, is a variable in cryptography that is used with an algorithm to encrypt and decrypt code. Secret keys are only shared with the key's generator, making it highly secure. Private keys play an important role in symmetric cryptography, asymmetric cryptography and cryptocurrencies.

A computerized wallet stores the private key of a client. At the point when an exchange is started, the wallet programming makes a computerized signature by handling the exchange with the private key. This maintains a protected framework since the best way to produce a substantial mark for some random exchange is to utilize the private key.

Online wallets are divided into hybrid and traditional ones. The first method involves separate storage of keys using multi-signature, the second-private keys are stored on the service, and only a backup copy is available to the user.

A digital wallet stores a user's private key. When a transaction is initiated, by processing the transaction with the private key, the wallet program produces a digital signature. This ensures a stable mechanism since using the private key is the only way to produce a legitimate signature for any given transaction.

If I may get u or understand u? You said, you have the (data file) where all private and public keys are derived from. Meaning where the keys are generated from randomly and not the ones the network or system had already generated to be executed at a particular time. So, it's either the online wallet network or system has a backup it can use to confirm sending and receiving of funds or it doesn't work at all. For example, u travelled and left your door keys to your next neighbor for some holidays leaving some spare ones with u in some corner of your brief case, now u are back from your trip seeing that your neighbor u left your keys with has also travelled on an emergency base forgetting he/she have to also leave your keys behind in a protective and private way before going. I don't think u have to stand still waiting for your neighbor to come before entering your room since u also took a smart step in keeping some spare keys with u before traveling. Also, note that (public and private keys) are what allows a user to be able to access hi/her cryptocurrency. Without them a user can't send or receive money not neither check amount in wallet. Thank u

One of the best parts of crypto is being able to store money with just a private key or seed key – like a 12 word passphrase. One of the worst parts of crypto, however, is that storage and security of your passphrase is entirely in your hands.

If you lose your private key or seed key, then there’s no bitcoin customer service hotline you can call to recover your funds. People can lose – and have lost – millions of dollars of bitcoin because they’ve lost their private keys. In fact, it’s estimated that 4 million bitcoins (out of the 21 million total supply) are unrecoverable because the private keys are missing.
