- A Digital Certificate, or “Public key certificate”, is an electronic document used to cryptographically link a Public Key to its owner, making it possible to perform an authentication of its identity.
- The difference between a Digital Certificate and a Public Key is that the former contains more information, including the Public Key itself along with metadata and the digital signature for that document, while the latter is just the “encrypting tool” through which it is possible to perform and manage cryptographic processes when used in pair with its Private Key.
- Digital Certificater are mainly used to secure SSL connections between web browsers and web servers, to share the keys used for public key encryption and authentication of digital signatures, and in general to be able to access information while verifying its ownership.
- Certificate Authorities are generally third parties entrusted with the ability and responsibility of issuing digital certificates and creating a “trustable” ecosystem.

A digital certificate are used for encryption and digital signatures which creates trust between different entities. Through the certificate you can proof the ownership of your public key. A certificate contains the public key, additional information about the entity, some metadata and also a digital signature of the relating public key which was created by the issuer of the certificate

The difference between a public key and a digital certificate is that in case of a digital certificate a third party (certificate authorities or PKI) distribute the public keys and also sign them to ensure the security and creating trust and validation of the public key. A “normal” public key can be generated by yourself which means there is no central authority which validates who is belonging to the public key. Through a valid digital certificate it is ensured which entity/person belong to the public keys.

The most common use cases is SSL. These digitical certificates are used from nearly every website to proof that the web server from the domain belongs to the entity that owns the domain. The certificates are used for authentification between browsers and servers within the web.

1.Digital certificate is a public key that is used to cryptographically connect and identify the true owner of the message being encrypted and communicated on the network. Therefore it can be authenticated in order to approved it’s validity.
2. The digital certificate needs to be authenticated before the entity trust it because it needs to sign digitally while as the digital signature is optional to use digital certified format.It can be verified through using the the public key already generate from the private key using SHA 256, then hashed again and encrypted in public key for the digital signature.
3. The most common use case for digital certificates are used by web servers and web browsers (SSL- secure socket layer )to verify and communicate data over the internet as well as linking domain back to it’s owner.
4. A certificate authority (CA) is like a central authority or third party entity that approves your digital certificate after you submit to verify that identity matches with official records and now that you are clear to proceed with trust and integrity.

What is the difference between a digital certificate and a public key?
Further than the public key itself, a digital certificate encloses a digital signature created by the issuer (private key). The digital certificate enables entities to share their public key in a way that can be authenticated.
What is the most common use case for digital certificates?
Digital certificates are used in public key cryptography functions; they are most commonly used for initializing secure SSL connections between web browsers and web servers. Digital certificates are also used for sharing keys to be used for public key encryption and authentication of digital signatures.
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.
