- A digital certificate is used to cryptographically link ownership of a public key with the entity that owns it.
2)In public key cryptography; digital signatures are generated using algorithms for signing of data, with the result that a recipient can irrefutably confirm that the data was signed by the holder of a particular public key. Whereas digital certificates themselves are signed digitally, they should not be trusted unless the signature can be verified.
3)to retrieve the public key of and information about an entity and verify the ownership. This implies functionality of a public/private key pair
4)It is a trusted third party that issues digital certificates in the PKI context.

Is also known as a public key certificate, is used to cryptographically link ownership of a public key with the entity that owns it. -
What is the difference between a digital certificate and a public key?
Digital certificates include the public key being certified, identifying information about the entity that owns the public key.
Public key cryptography depends on key pairs: one [private key] to be held by the owner and used for signing and decrypting and one public key that can be used for encrypting data sent to the public key owner or authenticating the certificate holder’s signed data.
- What is the most common use case for digital certificates?
-
Websites use digital certificates for domain validation to show they are trusted and authentic.
-
Digital certificates are used in secure email to identify one user to another and may also be used for electronic document signing. The sender digitally signs the email, and the recipient verifies the signature.

- A digital certificate, which is known a public key certificate as well, is used to cryptographically link the ownership of a public key to the entity that owns it. Digital certificates purpose is for sharing public keys for encryption and authentication.
2) What is the difference between a digital certificate and a public key?
- The digital certificate include the public key being certified, identifying information about the entity that holds that specific public key, metadata related to the digital certificate and a digital signature of the public key that the issuer created.
- The public key itself is part of the digital certificate and has two main functions:
- Encrypting data sent to the public key owner;
- Authenticating the certificate’s holder signed data.
3) What is the most common use case for digital certificates?
- The most common case of use for digital certifications is for initializing secure SSL connections between the clients (web browser) and web servers. Digital certificates are used also for sharing keys that are used for public key encryption and for authentication of digital signatures.
4) What is a certificate authority?
- Certificate Authority (CAs) are third-parties that are trusted in the context of a PKI (Public Key Infrastructure). They are the ones who normally issue the digital certificates.

The difference between a digital certificate and a public key is that only the owner can access the private key to decrypt messages that are encrypted with corresponding public key. Signed digital certificate is an industry standard method of verifying the authenticity of an entity, such are a server, a client or an application. The digital certificate enables entities to share their public key so it can be authenticated. Digital certificates include the public key being certified, identifying information about the entity that owns the public key.

Digital certificates are authenticating the identity and providing secure electronic communication and data exchange between people, systems and devices online. Most commonly they been used in public web servers and internet facing servers, to secure websites, web servers, devices connected to web, any sort of code, software, signatures, also used in the email, HTTPS, FTPS,`WebDAV. Digital Certificates prove that websites and genuine and users are legitimates.
