Create RSA Public Private Keys in PEM format.

rsa-to-pem.go

privateKey, err := rsa.GenerateKey(rand.Reader,2048)

	privKey := pem.EncodeToMemory(&pem.Block{
		Type: "RSA PRIVATE KEY",
		Bytes: x509.MarshalPKCS1PrivateKey(privateKey),
	})
	pubKey := pem.EncodeToMemory(&pem.Block{
		Type: "RSA PUBLIC KEY",
		Bytes: x509.MarshalPKCS1PublicKey(&privateKey.PublicKey),
	})

	fmt.Println("------------------------")
	fmt.Println(string(privKey))
	fmt.Println("------------------------")
	fmt.Println(string(pubKey))
	fmt.Println("------------------------")
