public key
Explanation
### Why this is right
A certificate associates the subject's identity information with a public key. This lets others assess whether a public key belongs to the named subject.
### The concept
A Certificate Authority checks a certificate request and signs the resulting certificate. The certificate's signature can be verified, but trust also depends on accepting the CA and checking that the certificate details and validity suit the intended use.
### Terms

### Remember
A certificate binds an identity to a public key; it does not contain the subject's private key.
