Asymmetric cryptography

Public key cryptography (aka "asymmetric cryptography")

uses unique keys to secure information.

These keys are based on

mathematical functions called "one-way":

it is easy to calculate them in one direction,

but very hard to calculate their inverse direction.

💡 Symmetric-key cryptography are algorithms that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext.
