Security-related question about a possible exposed credential

[Emma-NYL]

Hello,

My name is Emma, I am conducting an academic study on possible credential exposure in public GitHub repositories.

While analyzing this repository, I found a string that may represent a credential. I'm including the code snippet below containing possible leakage. To avoid exposing sensitive information publicly, I marked the sensitive information.

Could you please help clarify whether the detected string is:

1. a real credential, or
2. a placeholder / example value?

Thank you for your time.

Code snippet (sensitive values masked):

/*
HookServe is a small golang utility for receiving github webhooks. It's easy to use, flexible, and provides strong security though GitHub's HMAC webhook verification scheme.
    server := hookserve.NewServer()
    server.Port = 8888
    server.Secret = "super****etcode"
    server.GoListenAndServe()

    for {
        select {
        case event := <-server.Events:
            fmt.Println(event.Owner + " " + event.Repo + " " + event.Branch + " " + event.Commit)

Thank you in advance for your time - I really appreciate it!

Sincerely,
Emma
