# Tonic Testing Certificates This directory contains certificates used for testing interop between Tonic's implementation of gRPC and the Go implementation. Certificates are generated using [`terraform`][tf]. To regenerate certificates for some reason, do the following: 1. Install Terraform 0.12 (or higher) 1. From the `cert-generator` directory, run: 1. `terraform init` 1. `terraform apply` This will generate certificates and write them to the filesystem. The effective version should be committed to git.
