You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: authorizers.go
    path of file: ./repos/go-swagger/examples/composed-auth/auth
    
    the code of the file until where you have to start completion: package auth

import (
	"crypto/rsa"
	"os"

	errors "github.com/go-openapi/errors"
	models "github.com/go-swagger/go-swagger/examples/composed-auth/models"
	jwt "github.com/golang-jwt/jwt/v5"
)

const (
	// currently unused: privat
    
func init() {
	// emulates the loading of a local users database
	userDb = map[string]string{
		"fred": "scrum",
		"ivan": "terrible",
	}

	// loads public keys to verify our tokens
	verifyKeyBuf, err := os.ReadFile(publicKeyPath)
	if err != nil {
		panic("Cannot load public key for tokens")
	}
	verifyKey, err = jwt.ParseRSAPublicKeyFromPEM(verifyKeyBuf)
	if err != nil {
		panic("Invalid public key for tokens")
	}
}
