Hello, Since protobuf library uses std::string for bytes fields, I'm wondering whether it is possible to securely clear the memory that contains sensitive data (e.g. secret keys)? At the moment, I use the following code just before protobuf object destruction:
for (volatile auto &c : buf.mutable_field()) c = '\0'; However, I'm not sure that it is enough since std::string can reinitialize memory freely during specific operations and leave its content uncleared. For protobuf object initialization, I use ParseFromArray method and I can definitely clear that initial array, but can I somehow ensure that a created protobuf object itself has all sensitive fields cleared? -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
