  1. What is a digital certificate?
    A digital certificate cryptographically links ownership of a public key with the entity that owns it. It can be defined as electronic credentials that bind the identity of the certificate owner to a pair of electronic encryption keys, one public and one private, that can be used to encrypt and sign information digitally.

  2. What is the difference between a digital certificate and a public key? A public key is used for encryption of data sent to the public key owner or authentication of the certificate holder’s signed data. The digital certificate enables entities to share their public key in a way that can be authenticated.

  3. What is the most common use case for digital certificates? They are most commonly used for initializing secure SSL connections between web browsers and web servers.

  4. What is a certificate authority? A certificate authority (CA) is a trusted entity that manages and issues security certificates and public keys that are used for secure communication in a public network.

  1. What is a digital certificate?

In asymmetric cryptography, a particular entity owns a pair of keys – a private key and a public key. While the private key must not be shared with anyone, the public key may be shared with any party that the owner of the private key wants to engage with in exchanging cryptographically secured information. However, a key step is to ensure that the public key, that is distributed to those parties, actually was derived from the corresponding private key of the entity - otherwise the private-public-key communication (encryption and decryption) runs the risk of being compromised by a fraudulent third party. A digital certificate enables entities to share their public key in a way that allows the recipients to authenticate whether or not the public key they received was actually derived from the private key of the entity that is supposed to be the owner of that private key (the entity is of course the owner of both, the private and the corresponding public key).

  1. What is the difference between a digital certificate and a public key?

A public key is a tool that is used in asymmetric cryptography to encrypt and decrypt data and to verify authenticity of data. A digital certificate is used to certify the ownership of a public key by a specific entity. In other words, a digital certificate is used to authenticate the validity of the public key itself, meaning it is used to verify that the public key was indeed derived from a particular entity’s corresponding private key.

  1. What is the most common use case for digital certificates?

The most common use case of digital certificates is the initialization of secure SSL connections between web browsers and web servers, i.e. establishing a secure communication channel between the client and the server.

  1. What is a certificate authority?

This is a trusted third party that issues digital certificates. It is a service provider that offers its Public Key Infrastructure to be used by customers for public-key encryption.
