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):

        "github.com/premshree/go-flickr"
        "github.com/sethgrid/pester"
)

const (
        API_KEY             = "YOUR****-KEY"
        API_SECRET          = "YOU-A****ECRET"
        PHOTO_SIZE_ORIGINAL = "Original"
        BACKUP_DIR          = "/path/t****ckup-dir"
        CONFIG_PATH         = "/path****config"
        NOT_IN_SET          = "not-in-set"
)

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

Sincerely,
Emma
