Public key cryptography \u2013 as used in Bitcoin \u2013 instead of using only one secret key, gives users two keys:\u00a0<strong>a private key and a public key.<\/strong><\/p>\n<p><strong>The public key<\/strong>\u00a0(which is always generated from your private key) is used to ensure that you are the owner of an address that can receive funds. It is public in the sense that nothing happens if you distribute it freely, no one will be able to access your funds. From this public key, your wallet address (the address you share to receive funds) is calculated.<\/p>\n<p><strong>The private key<\/strong>\u00a0is the one that gives you ownership of the funds at a certain address. In other words, it is the real \u201ckey\u201d that opens the safe and, whoever has it, will also have control over the money.<\/p>\n<p>Private keys are composed of a 256-bit sequence of letters and numbers, which makes them impossible for a human being to remember (unless you are a super human like\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/who-is-vitalik-buterin\/\">Vitalik Buterin<\/a>)<\/p>\n<p>For your better understanding, this is an example of a private key:<\/p>\n<p><strong>663FX930BD39832300FK6173D3C332623A79C6DM73F67F55C86E9873D7973A07<\/strong><\/p>\n<p>This is where seed phrases come into play and thanks to them the user gets\u00a0<strong>a simple and friendly way<\/strong>\u00a0to interact with their private keys.<\/p>\n<p>The process transforms these alphanumeric characters into a combination of common, memorable words in a specific, unique order. For example:<\/p>\n<p><strong>home ironing board trolley knee fever championship fever blanket hat elephant llama library robot<\/strong><\/p>\n<p>The sum of these words in the correct order equals your private key and with it\u00a0<strong>you can access your funds whenever and wherever you want<\/strong>, even if you have lost your phone or the\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/the-3-best-cold-wallets-to-hold-cryptocurrencies\/\">cold wallet<\/a>\u00a0where you keep your cryptos.<\/p>\n<p>So if, as in the example above, you are going to\u00a0<a href=\"https:\/\/www.bitnovo.com\/en\/buy\/bitcoin\/\">buy Ethereum<\/a>\u00a0with a credit card or you are going to buy any other cryptocurrency with another means of payment you should always write down and keep your security seed under safekeeping.
