要将ECC(椭圆曲线加密)私钥导入OpenSSL的EC_KEY,可以按照以下步骤进行操作: 1. 生成ECC私钥:使用OpenSSL命令生成ECC私钥,例如使用secp256k1曲线生成一个256位...

2、创建 EC_KEY 通过 NID_secp256k1 // curve 参数传 NID_secp256k1 - (EC_KEY *)createNewKeyWithCurve:(int)curve { // 生成EC_KEY对象 int asn1Flag = OPENSSL_EC_NAMED_CURVE; int form = POINT_CONVERSION_UNCOMPRESSED; EC_KEY *eckey = NULL; EC_GROUP *group = NULL; eckey = EC_KEY...
