The Private Key is a sophisticated form of cryptography that allows users to access their 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.
The Public key is a cryptographic code that allows users to receive cryptocurrencies into their personal wallet (account). The public key coupled with the private key are significant tools required to ensure the security of the crypto economy. It is an encryption technique that uses a paired public and private key (or asymmetric key) algorithm for secure data communication.
When dealing with cryptocurrencies, 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.
A private key is shared only with the key’s initiator, ensuring security. For example:
In short, sending encrypted messages requires that the sender use the recipient’s public key and its own private key for encryption of the digital certificate. Thus, the recipient uses its own private key for message decryption, whereas the sender’s public key is used for digital certificate decryption.
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 mail box, 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 mail box can be compromised.
Remember that if you don’t have the private keys of your crypto, you are not the real owner! There’s no perfect way to store your crypto assets , but do not ever disclose your private keys to anyone and make sure you are storing them safely! It will help you a lot throughout your Crypto Adventure!
