ECC process is very different from RSA, ECC involves a lot of additional concepts, such as group and so on, in addition ECC contains two different sets of mechanisms, this is ECDSA and ECDH, these two sets of mechanisms unified in ECC, in non-ECC

The process of ECC is quite different from that of RSA. ECC involves many additional concepts, such as group. In addition, ECC includes two completely different mechanisms, namely, ECDSA and ecdh, these two sets of mechanisms are unified in ECC. In

The ECC algorithm implemented by OpenSSL includes three parts: ECC algorithm (CRYPTO/EC), Elliptic Curve Digital Signature Algorithm ECDSA (CRYPTO/ECDSA) and Elliptic curve key exchange algorithm ECDH (CRYPTO/DH). Key data Structure The key data

After learning about the ECC concept, we know the meaning of group. In fact, group defines a curve, A, B, and order, in the implementation of OpenSSL, the Group also has an ec_method struct, which contains a series of functions. As the name suggests,
