Google credential verification

Question

When you create credentials in the Google Developer Console , you can create several different types of credentials depending on which type is created, you can have any of the following

• Open API
• Customer id
• Customer secret
• Service Account Email Address

They all have different formats. I deleted the ones I publish.

• API public key: AIzaSyAcMvMr_bk91qRKZ5SGYEvF5HWjXVE7Xkk
• Customer ID: 1046123799103-d0vpdthl4ms0soutcrpe036ckqn7rfpn.apps.googleusercontent.com
• Client Secret: G5QtTuBDp6ejKraR0XodNwaW
• Service account email address: [e-mail] eaccount.com

Is there any way to test them in my application. What keys are they?

I use C #, but any information about which keys will be useful.

Perhaps I could come up with some kind of RegEx check for the client id and email service. But there must be a way to test them better than that.

Update:

Google allows you to check the access token, why there is no way to verify the credentials Check TokenInfo

Does not work.

 Convert.FromBase64String("AIzaSyAcMvMr_bk91qRKZ5SGYEvF5HWjXVE7Xkk"); 

Answer 1

The only way to verify the credentials is to try and use them and see if the server accepts them.

There is no checksum or algorithm that you can check, Google did not specify a format for these tokens so they can change it at any time. You can only consider them as opaque drops and just transfer them and see what the server is responding to.
