Google Cloud KMS Go io.Reader and rand.Source

This package provides a struct that implements Go's io.Reader and math/rand.Source interfaces, using Google Cloud KMS HSMs to generate entropy.

Usage

r, err := gcpkmsrand.NewReader("projects/my-project/locations/us-east1")
if err != nil {
  // handle error
}

// Directly
b := make([]byte, 32)
if _, err := r.Read(b); err != nil {
  // handle error
}

// Via the math package
rnd := rand.New(r)
rnd.Uint32()

Limitations

• The maximum number of random bytes is 1024 at this time.
