A public key is a cryptographic key that is used in asymmetric encryption to encrypt data or verify signatures; it can be shared openly. A public certificate, on the other hand, is a digital document that binds a public key to an individual or entity's identity, often issued by a trusted Certificate Authority (CA). While the public key is a component of the certificate, the certificate also includes information such as the owner's identity, the CA's signature, and validity dates, ensuring the authenticity and integrity of the public key.

How can one get a PKI certificate?
One can receive a PKI certificate, or a public-key infrastructure certificate, is by digitally signing and publishing the public key bound to a given user.
How does embedding a public key in a digital certificate protect it from impersonators?
Embedding the public key in a digital certificate protects it from impersonators by associating and binding a user's identity to the public key. A digital certificate is the user's public key that has been "digitally signed" by a trustworthy source trusted to sign it. And, instead of "trustworthy" you could use the word: reputable.
In a large environment which part of the public key infrastructure PKI is responsible for maintaining a certificate database?
Certificate Server (CS)
The use of certificate authorities to associate public keys with certain users is known as?

What is the difference between a key and a legend?

What is a Class 3 Public Primary Certification Authority?
Cross-Certificates OverviewA cross-certificate is a certificate issued by one Certificate Authority (CA) that signs the public key for the root certificate of another Certificate Authority. Cross-certificates provide a means to create a chain of trust from a single, trusted, root CA to multiple other CAs.

What does a digital certificate typically contain?
A digital certificate typically contains the subject’s name, the public key associated with the subject, the certificate authority's (CA) name, the digital signature of the CA, and the certificate's validity period. It may also include information about the certificate's purpose and the algorithms used for encryption. This information helps establish the identity of the certificate holder and ensures secure communications over networks.
