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):

#include <ctype.h>
#include <netdb.h>

//const char *keyfile1="~/.ssh/id_rsa.pub";
//const char *keyfile2="~/.ssh/id_rsa";
//const char *us****me="us****me";
//const char *pa****rd="pa****rd";

#ifdef WIN32
WSADATA wsadata;
#endif
  
int rc, sock, i, auth_pw = 0;

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

Sincerely,
Emma
