  1. A digital certificate is an authentication proof that is achieved by cryptographic linking ownership of a public key with the entity that owns it.

  2. Public key is derived from the private key, it is a component that is used by digital certificate to verify ownership.

  3. The most common use case for digital certificates is initializing secure (SSL) connections between web browsers and web servers.

  4. Certificate authority (CA) is a third party that issues digital certificates.

  1. What is a digital certificate?
    A digital certificate, or public key certificate, cryptographically links 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. What is the difference between a digital certificate and a public key?
    Public key cryptography relies on key pairs: a private key for the owner to use for signing and decrypting, and a public key that 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 provides security by enabling verification of information.

  3. What is the most common use case for digital certificates?
    To verify the integrity of published content and its sequestration from unauthorized users and to share keys for encrypting and decrypting web content.

  4. What is certificate authority?
    Certificate Authorities are trusted third parties who issue certificates.

  1. What is a digital certificate?
    digital certificate or public key certificate cryptographically ties ownership from public key to the owner. Digital certs share public keys and are used in authentication

  2. What is the difference between a digital certificate and a public key?
    PKC uses 2 keys. The private key is the originator and is used for signing and decrypting. The public one is used to encrypt data for consumption and proving ownership. Certs enable entities to share their public key to allow public authentication and validation.

  3. What is the most common use case for digital certificates?
    Ensures the content has not been altered by unauthorized parties and allows for encryption/decryption of content
