# go-grpc-certificate
|

|
|
|
||
|
|
## 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)
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
