Problem's context

I've got some trouble while I want to use gRPC through TLS certificates. I've created a certificated from a .pem key file which had a password and I couldn't use it through go standard library. I found a solution based on this SO answer to this question


I've decided to use openssl to achieve this task as far as I was not able to found a solution in go standard library.

Installation requirements

I've used this version on development. So we should check if it backwards compatible.

$ openssl version
OpenSSL 3.0.8 7 Feb 2023 (Library: OpenSSL 3.0.8 7 Feb 2023)

How to use

In your go project you just have to type in your terminal:

$ go get

Then place in your code like this

package main

// here should be defined your imports
certcreds ""

func main() {
    certPath := "place your certificate path"
    certKeyPath := "place your key file path"
    keyPassword := "place your key password here"

    creds, err = certcreds.CredentialsFromKeyWithPasswd(
        certPah, certKeyPath, keyPassword,
    if err != nil {
        log.Fatalf("Failed loading certificates: %v\n", err)
