What is a public key encryption?

The public key is then used to encrypt data that can be decoded/ decrypted only with the help of the corresponding private key. This means that knowing / having the public key alone won’t get you the private key; it’s why this method is called asymmetric encryption and is known to be the safer option.

What is the difference between a public key and a private key?

While both the public and private keys strive to secure a transaction, they are distinctively different, corresponding with their purposes. When comparing them side-by-side, a public key is used to verify a transaction after a transaction has been requested. Commonly a public key is also translated as an ‘address’ to receive cryptocurrencies.

Do you need to know the math behind public key cryptography?

Fortunately, all of us can use and benefit from public key cryptography without needing to understand the complicated math behind it. In fact, we likely use public key cryptography everyday as we use computers and the Internet. Just imagine, what would the world be without it?

Why is private key symmetric?

In the Private key, the same key (secret key) is used for encryption and decryption. In this key is symmetric because the only key is copied or shared by another party to decrypt the cipher text. It is faster than public-key cryptography. In a Public key, two keys are used one key is used for encryption and another key is used for decryption.
