-## 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](https://stackoverflow.com/a/56131169/6329540)** to this **[question](https://stackoverflow.com/questions/56129533/tls-with-certificate-private-key-and-pass-phrase/56131169#comment132834574_56131169)**
-
-## Solution
-I've decided to use **[openssl](https://www.openssl.org/docs/manmaster/man1/)** 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.
-```shell
-$ 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:
-```shell
-$ go get gitea.urkob.com/urko/go-grpc-certificate
-```
-
-Then place in your code like this
-```go
-package main
-
-// here should be defined your imports
-certcreds "gitea.urkob.com/urko/go-grpc-certificate/pkg/credentials"
-
-
-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)
-    }
-}
-```
