README.md

go-gen-cert

Preamble

I've decided to create this project based on this example but with some improvements, which I would like to give thanks.

I had some trouble during TLS communication between both of my gRPC server and client. I've decided to create a tool to generate SSL certificates following a little of this guide.

TODO:

  • Create intermediate authority to sign certificates on behalf CA to add more security. If intermediate is hacked then you can revoke from CA and generate new intermediates keeping CA isolated from beeing hacked.

  • Complete tests

Configuration

If you are on dev environment, like I've been doing, you must create .env file similar as .env.example in this repo:

VIPER_CONFIG=your-viper-file-name-without-extension
VIPER_CONFIG_TYPE=yaml
ENV=dev

Then add viper configuration file, yaml for example, in your root directory:

export_dir: "/home"
ca:
    serial_number: 12152 # serial number
    subject:
        organization: "yourdomain.com"
        common_name: "*.yourdomain.com"
    key_usage: 1
    ext_key_usage: 
        - 1
        - 2
        duration: "8760h0m0s" #1 year
client:
    serial_number: 12151232 # serial number
    subject:
        organization: "yourdomain.com"
        country: "RM"
        province: "REML"
        locality: ""
        street_address: ""
        postal_code: ""
    subject_key_id:
        - 1
        - 2
        - 3
        - 4
        - 6
    key_usage: 1
    ext_key_usage: 
        - 1
        - 2
    duration: "8760h0m0s"

Execution

Then you can just run

go run main.go

tests

Just simply run make command and watch coverage results on cover.html within coverage

make test-coverage
rm -rf coverage
mkdir coverage
go test -v -coverprofile coverage/cover.out ./...
=== RUN   TestCredentialsFromKeyWithPasswd
--- PASS: TestCredentialsFromKeyWithPasswd (0.37s)
=== RUN   TestCredentialsFromKeyWithPasswdError
--- PASS: TestCredentialsFromKeyWithPasswdError (0.46s)
PASS
coverage: 90.9% of statements
ok      gitea.urkob.com/urko/go-grpc-certificate/pkg/credentials        0.839s  coverage: 90.9% of statements
go tool cover -html coverage/cover.out -o coverage/cover.html
