   Digital certificates are used for sharing public keys. It links the public key with the owner of the public key (the holder of the private key).

2. What is the difference between a digital certificate and a public key?
   a public key is part of the digital certificate.
   the digital certificate includes:
   a) the public key
   b) information of the owner of the public key
   c) the digital signature and
   d) some metadata

1- A digital certificate cryptographically links ownership of a public key with the entity that owns it. It also allows for the sharing of public keys & has identifying information about whoever owns the public key in addition to a digital signature of the public key created by the issuer of the certificate.

2- A public key is used for encryption and authentication of data (verifying data), whereas a digital certificate links public keys to specific owners.

3- The most common use case is to ensure secure connections between web clients and servers; meaning connections in which content has not been changed by unauthorized users.

4- A certificate authority issues the majority of digital certificates and is a trusted third party.

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

2. The difference between a digital certificate and a public key is that the digital certificate is used to show ownership and contains the public key, while a public key is for encryption and authentication.

3. The most common use case for digital certificates is to link a web server for a domain to the individual or organization that owns the domain.

4. A certificate authority (CA) is considered a trusted 3rd party that issue certificates in the context of a PKI, enabling individuals to extend their trust in the CA to the trustworthiness of the digital certificates that it issues. Although it is possible for an entity to create its own PKI and issue its own digital certificate, most digital certificates are issued by a CA.

[jostrings]

1. What is a digital certificate?
   Authentication of digital signature or the authenticity of data

2. What is the difference between a digital certificate and a public key?
   The public key is the receiving function of a one way hash function and the digital certificate will in simple terms confirm the ownership of the public key

3. What is the most common use case for digital certificates?
   They are commonly used for initializing secure SSL connections on the web as I understand it

4. What is a certificate authority?
   It’s a trusted third party by one or more of the involved parts. If the issuer and the user don’t trust the CA, then it will be a situation where the government in the country requires a CA and the government trust the CA in this example while the other parties just accepts the CA in order to do what both parties agreed to

Reading Assignment: Digital Certificates

1 . What is a digital certificate?

A Digital Certificate is an electronic “password” that allows a person, organizaion to exchange data securely over the Internet using the public key infrastructure (PKI). Digital Certificate is also known as a public key certificate or identity certificate

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

The owner of the key pair makes the public key available to anyone, but keeps the private key secret. A digital certificate verifies that an entity is the owner of a the public key. If user a sends a encrypted message together with the receivers public key, the receiver can decrypt the message with his private key.

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

To ensure users identity by cryptography functions, or initialization of SSL connections between servers to gain trust.

4. What is a certificate authority?

It’s a central authority , usually a trusted security firm that charges customers to issue certificates

[MSeeman]

1. AKA Public Key Certificate, is used to cryptographically link ownership of a public key to the entity that owns it and used for the sharing of public keys for encryption and authentication of traffic

2. (I’m curious if this question should have read, based on the reading assignment, “whats the difference between a digital certificate & digital signature”)
   This is an odd question considering a digital certificate contains a public key and works in many the same way as users do their public/private key pair… However, 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 created by the issuer of the certificate.

3. Securing traffic between a web browser and web server

4. A trusted third party on the internet which issues and validates a digital certifiacte

• What is the difference between a digital certificate and a public key?
  Digital certificates are also known as public keys because they are used in public key cryptography functions. A public key identifies information of the entity that owns it and a digital certificate is used to cryptographically link the owner of the public key to the entity owned.

• What is the most common use case for digital certificates?
  They are used for sharing public keys to be used for encryption and authentication of digital signatures. They are also commonly used for initializing secure SSL connections between web browsers and web servers.

• What is a certificate authority?
  A CA is a trusted third party that issues digital certificates. Together they develop a secure network infrastructure for user access, keep data secure and eliminate hacker threats.

[Laszlo_Leonardo]

1, digital certificate is a digital notification, mostly according to the standards of the ITU-T or the IETF, of the personal characteristics of persons or of possession and the authenticity and the passage through cryptographic procedures.
2 a digital certificate is a document that usually uses a digital signature that binds together that I am the owner of a special public key and identify me as me
3 SSL between backend (Server) and Client (Browser)
4 a organisation that validates that I am the owner of this public key

[confusius]

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.

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.

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.

A certificate authority (CA) is a trusted entity that issues digital certificates, which are data files used to 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.
