Decode a client secret

To calculate a request signature, an extension must decode the app's client secret into a byte array. This page demonstrates how to decode a client secret with a few different programming languages.
Go
1
package main
2
​
3
import (
4
    b64 "encoding/base64"
5
    "fmt"
6
    "log"
7
)
8
​
9
func main() {
10
    secret := "CLIENT SECRET GOES HERE"
11
    key, error := := b64.StdEncoding.DecodeString(secret)
12
​
13
    if error != nil {
14
        log.Fatal(error)
15
    }
16
​
17
    fmt.Println(key)
18
}

Java
1
import java.util.Base64;

​
3
public class Example {
4
    public static void main(String[] args) {
5
        String secret = "CLIENT SECRET GOES HERE";
6
        byte[] key = Base64.getDecoder().decode(secret);
7
        System.out.println(key);

    }

JavaScript
1
const secret = "CLIENT SECRET GOES HERE";
2
const key = Buffer.from(secret, "base64");
3
console.log(key);

PHP
1
$secret = "CLIENT SECRET GOES HERE";
2
$key = base64_decode($secret);
3
echo($key);

1
const secret = "CLIENT SECRET GOES HERE";
2
const key = Buffer.from(secret, "base64");
