## Elliptic Curves Cryptography
Elliptic Curves Cryptography (ECC) is an asymmetric cryptography based on the algebraic structure of elliptic curves over finite fields. The encryption algorithm is irreversible. It is easy to calculate in one direction, but it cannot be reversed in the opposite direction. For example, the private key can generate the corresponding public key through the ECC operation, but the public key cannot reversely derive the private key.
