在C中实现ECC

#include<stdio.h>
#include "tiny_ecc_shared.h"

int main() {
    uint8_t private_key[32];
    uint8_t public_key[64];
    const struct uECC_Curve_t * curve = uECC_secp256r1();

    // 生成私钥
    uECC_generate_random_bytes(private_key, sizeof(private_key));

    // 生成公钥
    if (uECC_compute_public_key(private_key, public_key, curve)) {
        printf("Public key: ");
        for (int i = 0; i< sizeof(public_key); i++) {
            printf("%02X", public_key[i]);
        }
        printf("\n");
    } else {
        printf("Error: Failed to generate public key.\n");
    }

    return 0;
}
