I understand on a conceptual level that a certificate is nothing more than just a verified public key. The next question I have, is how exactly do I see the contents of a certificate? Apart from the public key it verifies are there other information that the certificate contains? Does the certificate also contains the signature of the public key etc. etc.

Pointers on how to further explore certificates would be appreciated!

**Edit**
I am mostly thinking about the ones used with HTTPS/TLS
