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):

*/
abstract class AuthBase implements AuthInterface {

	/** Name of the session variable */
	const SESS_VAR = 'DoPhp::Auth';
	/** Name of the session array username key */
	const SESS_VUSER = 'username';
	/** Name of the session array password key */
	const SESS_VPASS = 'password';

	/** String (char) used to concatenate salt and password */
	const PWD_SALT_GLUE = '$';

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

Sincerely,
Emma
