ECDSA_SIG *signature = ECDSA_do_sign(hash, strlen(hash), eckey); This is a technique to display the values of r and s: printf("(sig->r, sig->s): (%s,%s)\n", BN_bn2hex(ECDSA_SIG_get0_r(signature)), BN_bn2hex(ECDSA_SIG_get0_s(signature))); Thanks Best Regards Solution...

1. 消息方将签名内容,分离出r、s ,即sig(ECDSA_SIG结构体的内容为BIGNUM *r、*s) 2. 将获得的消息源内容,算出摘要dgst 3. 获取公钥。 导入到签名验证函数中进行验证 1 ECDSA_verify(inttype,constunsignedchar*dgst,intdgstlen,constunsignedchar*sig,intsiglen, EC_KEY *eckey); 若验证ok,返回1,否则返...
