Description: CKey GetPubKey is a function in C++ programming language that returns the public key associated with a given private key. This function is commonly used in cryptographic applications where it is necessary to transmit or store the public key, which is used to authenticate the sender and encrypt messages.
Code Examples: 1. Here is an example of how to use CKey GetPubKey in the Bitcoin Core library to get the public key associated with a private key:
CKey key; // ... set up the private key ... CPubKey pubKey = key.GetPubKey();
2. Another example is using the SeCP256k1 library in the Bitcoin Unlimited (BU) software to get the public key from a private key:
const secp256k1_context *ctx; secp256k1_ecdsa_signature signature; unsigned char pubKey[65] = {0}; size_t pubKeySize = sizeof(pubKey); // ... set up the private key ... secp256k1_ec_pubkey_create(ctx, pubKey, &pubKeySize, privateKey, 1);
Package Library: The CKey GetPubKey function is part of the Bitcoin Core and other related software libraries that use the Bitcoin protocol. These libraries include OpenSSL, SeCP256k1, and Boost libraries.
