How to identify github user with ssh key?

Question

I want to disable a working git ssh key. But do not know the owner of the ssh key. For both disabling the key or removing the user, I would need to know the user details.

The file:.git/config does not include the user information.

And I face the below error when I try to commit

*** Please tell me who you are.

Run 

  git config --global user.email "[email protected]"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

FYI: The key is SAML authorized.

Can I know if there is a way we can find the git user using the ssh key?

You can inspect authorized_keys and afterwards take a look into the public key usually in the comment part you should see the user or machine <algorithm> <key> <comment> — dejanualex

Unfortunately, the machine only has a private key, no public key found inside the machine. — Dwarakanath Thoppe

You can convert a private key to public: stackoverflow.com/a/38290956/7976758 — phd

@phd But the generated public key will not have the user email in the comment right? — Dwarakanath Thoppe

You can connect to Github using that public key

ssh -T [email protected]

Returns:

Hi githubUser! You've successfully authenticated, but GitHub does not provide shell access.
