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- The digital certificate enables entities to share their public key in a way that can be authenticated. A digital signature enables encryption and authentication, and are generated using algorithms for the 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.

3-Digital certificates are used to provide assurance that published content has not been modified by any unauthorized actors, and to share keys for encrypting and decrypting web content.

4- A trusted third party that has the ability to issue digital certificates.

  1. A public key certificate used to cryptographically link ownership of a public key with the entity that owns it. Basically If I give it to you, I link to you ownership of my public key.
  2. A digital certificate has, not only the public key, but metadata of the certificate itself and a signature of the entity that identifies the public key.
  3. To verify/authenticate ownership of websites (SSL certificates).
  4. A trusted third party that can give digital certificates to you.

  1. What is a digital certificate? Used to cryptographically link ownership of a public key with the entity that owns it.
  2. What is the difference between a digital certificate and a public key? Public key cryptography depends on key pairs: one a private key to be held by the owner and used for signing and decrypting, and one a public key that can be used for encryption of data sent to the public key owner or authentication of the certificate holderā€™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? Initializing security SSL connections between web browsers and web serves. Digital certificates are also used for sharing keys to be used for public key encryption and authentication of digital signatures.
  4. What is a certificate authority? 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.
