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):

                session("id", user.id.toString());
                if (user.getToken() == null)
                        return CtrlUser.resetToken(true);
                return redirect(destination);
        }
        
//        private static String loginApplicationSecret = "Se****Key";
//        private static String generateSessionToken(User user) {
//                String secret = user.getEmail() + Long.toString(user.lastLogin.getTime()) + Login.loginApplicationSecret;
//                try {
//                        return MessageDigest.getInstance("SHA-512").digest(secret.getBytes()).toString();
//                } catch (NoSuchAlgorithmException e) {
//                        throw new RuntimeException(e);

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

Sincerely,
Emma
