  1. A Digital Certificate is also referred to as a Public Key Certificate cryptographically links the ownership of a private key with the entity that owns it. It includes the public key being certified, identifying information on the owning entity, meta data related to the signature and a digital signature of the public key created by the issuer.
  2. A Public Key is a very large numerical number that is generated and used together with a hashing algorithm on data to determine if the result is the same as that obtained when a related Private key is used to hash the same data thus ensuring authenticity of the data as well as the sender of the data. A Digital signature enables entities to share their public key in a way that the data transmitted can be authenticated
  3. Their most common use is to by Web Servers and Web Browsers to authenticate information over the internet. They are used for initiating secure SSL connections between the browsers and the server. Digital certificates are used to share Public keys for encrypting and decrypting web content. they are also used online and offline for providing cryptographic data privacy.
  4. A Certificate Authority is an appropriate trusted independent third party that issues Digital Certificate

1. What is a digital certificate?

A digital certificate is a certificate that cryptographically links ownership of a public key with the entity that owns it. These certificates are used to share public keys for encryption and authentication.

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

A digital certificate is just a certificate that verifies a particular entity is the owner of a particular public key. The public key itself is what is needed to generate the digital certificate.

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

The most common use case is to initialize SSL connections between web browsers and web servers.

4. What is a certificate authority?

A certificate authority is a third party that is trusted to issue digital certificates.

  2. Public key cryptography depends on key pairs: one a 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.
  3. they are most commonly used for initializing secure connections between web browsers and web servers. Digital certificates are also used for sharing keys to be used for public key encryption and authentication of digital signatures.
  4. The vast majority of digital certificates are issued by a (CA). CAs are considered trusted third parties.

Digital certificates verify ownership of a public key

The digital certificate contains the public key as well as the digital signature of the authority who issued it having verified the identity of the owner

secure socket layer (SSL) connection between web client and host server.

CA are the trusted authority who issues digital certificates

  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 certificate is much broader than a public key in which it contains more information. It contains the public key being certified, the information about the entity that owns that public key, and the digital signature of the public key created by the issuer.
    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

  3. Digital certificates are most commonly used for initializing secure SSL connections between web browser and web servers

  4. Certificate authority are 3rd party digital certified enablers on the hyperledger network

  1. What is a digital certificate?

A digital certificate is a credential in the form of an electronic document and provides proof of ownership. It serves as a tool so users can confirm that the electronic information send comes specifically from the certified user.

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

A digital certificate is only uses as a means to confirm that the information shared comes from the verified users. Public keys can also be used to send back encrypted messages to the user that owns the private key of that public.

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

Digital certificates are mostly used for establishing SSL connections between browsers and web servers.

  1. What is a certificate authority?

This is the authority (trusted third party) that gives out the digital certificates.

  1. What is a digital certificate?
    A digital certificate is an electronic document that is used when communicating over the Internet, and allows you to confirm the identity of the sender. t contains a key which secures the exchange of information over the Internet. Digital certificates contain core information about an individual, a machine or company and associate this digital identity with a key pair, made of a public key and a private key. A digital certificate is issued by a Certification Authority (CA).

  2. What is the difference between a digital certificate and a public key?
    In cryptography, a public key certificate (also known as a digital certificate or identity certificate ) is an electronic document which uses a digital signature to bind together a public key with an identity — information such as the name of a person or an organization, their address, and so forth.
    A digital signature is used to verify a message. It is basically an encrypted hash (encrypted by the private key of the sender) of the message. The recipient can check if the message was tampered with by hashing the received message and comparing this value with the decrypted signature.
    To decrypt the signature, the corresponding public key is required. A digital certificate is used to bind public keys to persons or other entities. If there were no certificates, the signature could be easily be forged, as the recipient could not check if the public key belongs to the sender. The certificate itself is signed by a trusted third party, a Certificate Authority

  3. What is the most common use case for digital certificates?
    Digital certificates are used in public key cryptography functions; they are most commonly used for initializing secure SSL connections between web browsers and web servers. Digital certificates are also used for sharing keys to be used for public key encryption and authentication of digital signatures.
    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.

  4. What is a certificate authority?
    Digital certificates prove the ownership of a public key and certificates are only issued by an authority, known as the certification authority (CA). Certification Authority are well established entity, for which the vetting of identity, required to deliver a certificate, are trusted.
