![]() By definition, asymmetric encryption works as follows: if we encrypt data by a private key, we will be able to decrypt the ciphertext later by the corresponding public key: We want to encrypt and decrypt data using these keys. ![]() This is non-trivial and usually involves a design of hybrid encryption scheme, involving ECC cryptography, ECDH key exchange and symmetric encryption algorithm.Īssume we have a ECC private-public key pair. In this section we shall explain how to implement elliptic-curve based public-key encryption / decryption (asymmetric encryption scheme based on ECC).
