When it comes to the word encryption, we think of it as a technique that protects data using a cryptographic key, and there’s nothing wrong with this. However, what most people don’t realize is that there are certain types of encryption methods. Asymmetric encryption, also known as Public-Key cryptography, is an example of one type.
Unlike “normal” (symmetric) encryption, asymmetric encryption encrypts and decrypts the data using two separate yet mathematically-connected cryptographic keys. These keys are known as a ‘Public Key’ and a ‘Private Key.’ Together, they’re called a ‘Public and Private Key Pair.’
