  1. What is a digital certificate?

A digital certificate, also known as a public key certificate, is used to cryptographically link ownership of a public key with the entity that owns it.

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

A digital certificate is more about the ability to provide secure connection such as a SSL connection. A public key is used in connection with a private key. A public key can be 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.

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

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.

  1. What is a certificate authority?

The vast majority of digital certificates are issued by a certificate authority. CAs are considered trusted third parties in the context of a PKI; using a trusted third party to issue digital certificates enables individuals to extend their trust in the CA to the trustworthiness of the digital certificates that it issues.

  1. A digital certificate, also known as a public key certificate, is used to cryptographically link ownership of a public key with the entity that owns it. Digital certificates are for sharing public keys to be used for encryption and authentication.
  2. A digital signature can depend on the distribution of a public key in the form of a digital certificate – but it is not mandatory that the public key be transmitted in that form. However, digital certificates themselves are signed digitally, and they should not be trusted unless the signature can be verified.
  3. They are most commonly used for initializing secure [SSL] connections between web browsers and web servers.
  4. CAs are considered trusted third parties in the context of a PKI; using a trusted third party to issue digital certificates enables individuals to extend their trust in the CA to the trustworthiness of the digital certificates that it issues.
