protoc-gen-redact (PGR)

protoc-gen-redact (PGR) is a protoc plugin to redact field values in GRPC client calls from the server. This plugin adds support to protoc-generated code to redact certain fields in the GRPC calls.

Developers only need import the PGR extension and annotate the messages or fields in their proto files to redact:

syntax = "proto3";

package user;

import "redact/redact.proto";
import "google/protobuf/empty.proto";

option go_package = "github.com/arrakis-digital/protoc-gen-redact/examples/user/pb;user";

message User {
    // User credentials
    string username = 1;
    string password = 2 [(redact.redact) = true]; // default redaction

    // User information
    string email = 3 [(redact.custom).string = "r*d@ct*d"];
    string name = 4;
    Location home = 5;
    message Location {
        double lat = 1;
        double lng = 2;
    }
}

service Chat {
    rpc GetUser(GetUserRequest) returns (User);
    rpc GetUserInternal(GetUserRequest) returns (User) {
        option (redact.method_skip) = true;
    }
    rpc ListUsers (google.protobuf.Empty) returns (ListUsersResponse) {
        option (redact.internal_method) = true;
    }
}

message GetUserRequest {
    string username = 1;
}

message ListUsersResponse {
    repeated User users = 1;
}
