- Digital certificates include the public key being certified, identifying information about the entity that owns the public key, metadata relating to the digital certificate and a digital signature of the public key the certificate issuer created.
The distribution, authentication and revocation of digital certificates are the primary functions of the public key infrastructure PKI, the system that distributes and authenticates public keys.

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. Digital certificates are for sharing public keys to be used for encryption and authentication. -
What is the difference between a digital certificate and a public key?
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. -
What is the most common use case for digital certificates?
Digital certificates are most commonly used by 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. -
What is a certificate authority?
A third party issuer of digital certificates.

What is the difference between a digital certificate and a public key? A digital certificate establishes the linkage between an entity and the entities public key. The public key, itself, is merely a sequence to alphanumeric characters which can be used to decode anything encrypted with the corresponding private key, or alternatively can be used to encrypt data which can then only be decrypted by the corresponding private key.

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 holder’s
signed data. The digital certificate enables entities to share their public key in a way that can be authenticated. -
