Make sure to remember the password or store it in someplace safe. It should be very strong as to no one can ever guess or break it. Go ahead and encrypt once only when you are confident with your passphrase.

How to export private keys from your core wallet

This is the third most important thing which you should take note on. At the beginning of this guide we informed you that if you don’t own the private keys of your wallet address then you don’t own the funds that it holds. Private keys gives access to public address in blockchain.

Whenever you create a new wallet address (public address), a private key for the address is also generated. However for security reasons private keys are not displayed by your core wallet. You’ll have to export them using your wallet console.

Your may or may not have created several addresses. Remember that each and every public address holds a separate private key. If you hold coins in multiple address then it’s important that you are exporting the private keys of each and every address.

Private keys can be exported on all QT based wallets and it can be exported using the console tab on debug window. Here is a step by step instructions on exporting the private keys of your wallet address

Step 1: In your wallet go to Tools >> and open Debug Window.

Step 4: If your wallet is encrypted then you have to decrypt first before you can export the private keys. To unlock or decrypt your wallet

How to protect the funds in core wallet and Is this wallet Secure? – Security Tip

When  it comes to security; offline hardware wallets like Trezor and Ledger Nano s are a step ahead than desktop core wallets. If you are holding large amount of Bitcoins or Crypto assets then we suggest you to get yourself a hardware wallet to protect your funds. It doesn’t mean that desktop wallets are weak in terms of security and privacy. Since most of the time the core wallets are connected to the internet they are prone to more attacks than hardware wallets. However if you follow these safety measures then you can ultimately protect your wallet from hackers.

  1. Take a backup of your wallet and put it in a cold storage. For example external hard drive or pen drives which is not connected to the internet.
  2. Always encrypt your wallet beforehand and never store the encryption seed on your computer.
  3. Never ever setup your wallet on mining rigs or public computer. Keep the wallet in your personal computer.
  4. Additional online wallet security tip: If you are using an online wallet or holding funds in exchanges then it is recommended that you add Google 2 Factor Authenticator.

We hope this guide has enough explanation for any beginner to understand the fundamentals of crypto currency wallet.
