cert

package cert

This package contains functions for creating a local development root certificate that can then be used with net/http tlsConfig servers to dynamically generate SSL certificates in development.

The generated certificates are kept in-memory in a cache and are re-generated on next execution.

On macOS the certificate is installed into the system keychain (a password prompt is shown) so all generated certificates are trusted automatically.

Usage example

You need to run the root certificate creation step once:

  err := cert.CreateCert()

Now you can create an HTTPS server that uses the root certificate to generate valid certificates dynamically:

  cache, err := cert.NewCache()

  tlsConfig := &tls.Config{
    GetCertificate: cache.GetCertificate,
  }

See https://github.com/moomerman/phx-dev/tree/master/cert/example/main.go for a full example.
