How are you? By Allah's grace, I'm doing very well.

Cryptography is at the core of cryptocurrency and blockchain technology, and the two most important pillars of this cryptography are the public key and the private key. Simply put, these two keys or codes ensure the ownership and security of your digital assets.

1. Public vs. Private Key

To understand the relationship between these two keys, you can think of a digital bank account. The public key is like your bank account number or email address. You can give it to anyone so that they can send you crypto. It is open to everyone on the public ledger of the blockchain. The private key is like your account password or ATM PIN. With it, you order your assets to be spent or sent somewhere else. Whoever has your private key is the real owner of your funds.

2. Why is the security of private keys so important?

There is no central authority (such as a bank or customer care) in the world of cryptocurrency. If you lose your private key, your wallet money will be lost forever. There is no "Forgot Password" option to reset it. If someone steals your private key and removes your funds, it is impossible to cancel the transaction or get the money back.

3. Best ways to keep your private key secure

The following methods should be followed to keep your private key or its recovery format 'Seed Phrase' safe. Never save your private key or seed phrase in your mobile notebook, email, drive or social media. Hackers can easily steal them through the internet. The safest thing is to write it down on paper and keep it in a safe place (like a locker). Paper can be destroyed, so it is safer to engrave the seed phrase on a steel or metal plate. Hardware wallets like Ledger or Trezor always keep your private key offline in a chip. Even if your computer is hacked, the hacker cannot see your private key. If any website, support team, or individual asks you for your seed phrase or private key, be 100% sure it is a scam. No legitimate wallet or exchange will ever ask for this. Multi-signature wallets can be used for large amounts of funds. This requires the authorization of multiple private keys to complete a transaction. As a result, even if one key is stolen, the funds are safe.

4. Caution with public keys

While sharing public keys is safe, there are some things to keep in mind. Sometimes, a copied public key can change when pasted due to a computer virus. Therefore, it is important to check each letter before making a transaction. If anyone knows your public key, they can use Blockchain Explorer to see how much money you have in your wallet or where you are transacting. Therefore, it is good to use a new address occasionally to maintain privacy.

5. Digital Hygiene

Always use hardware or app-based (Google Authenticator) 2FA on your wallet app or exchange account. Do not make crypto transactions using free WiFi at cafes or airports. There is a fear of 'man-in-the-middle' attacks.

Conclusion

There is a common saying in the world of cryptocurrency— "Not your keys, not your coins". That is, if you do not have control over your private key, you have no rights to that asset. Therefore, it is very important to understand the security grammar of the technology before using it. Today's discussion concludes here. I hope you've found it interesting.
