What is the difference between a digital certificate and a public key?
Digital certificates are used by all major web browsers and web servers to provide assurance that published content has not been modified by any unauthorized actors, and to share keys for encrypting and decrypting web content. Digital certificates are also used in other contexts, both online and offline, for providing cryptographic assurance and privacy of data.

Reading Assignment: Digital Certificates
A digital certificate provides a way for users to share their public key so that it can be authenticated or tied back to the user.
The digital certificate contains additional information used to confirm the owner of the public key. In addition to the public key being shared, a digital certificate contains additional metadata about the owner of the public key, and is signed by the owner using their private key, which helps confirm their identity.
The most common use for digital certificates is the initiation of SSL connections between clients and servers.
Certificate authorities (CAs) are trusted third parties acting as a public key infrastructure (PKI). They are responsible for the âdistribution, authentication and revocation of digital certificatesâ. Examples include Verisign and Digicert. These CAs are trusted by the majority of modern browsers, so when they sign an SSL certificate used by a web site, your browser can extend the trust it has in the CA to the certificate provided by the web site.

The most common use of Digital Certificates is securing connections between web servers and web browsers over the internet which although originally done via SSL is now mainly done using TLS. The academy website for example uses TLS 1.2 or greater and does not support SSL anymore.
-
A Certificate Authority is a trusted 3rd party which issues digital certificates. Again using the academy website as an example its certificate is issued by Letâs Encrypt Authority X3, whose own certificate is issued Digital Signature Trust Co.

1.What is a digital certificate?
A digital certificate (or public key certificate) cryptographically links ownership of a public key with the entity that owns it. It involves certification of the public key and identifying info about the public keyâs owner. Also, metadata relating to the digital certificate and a digital signature of the public key by the certificate issuer.
2.What is the difference between a digital certificate and a public key?
Itâs all about the key pairs that public key cryptography depends on. That is, the ownerâs private key for signing and decrypting, and the public key for encryption of data sent to the public key owner (authentication of the certificate holderâs signed data).
The digital certificate enables entities to share their public key for authentication.
3.What is the most common use case for digital certificates?
Digital certificates are most commonly used for initializing secure SSL connections between web browsers and web servers.
