Digital Certificates - Reading Assignment

• What is a digital certificate?

  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?

  Public key cryptography enables a number of different functions, including both encryption and authentication. A digital signature is another one of those functions enabled by 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. 
  

• 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. 
  

• What is a certificate authority?

  Most digital certificates are issued by a certificate authority. CAs are considered trusted third parties.

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.

2. Digital certificates are also used for sharing keys to be used for public key encryption and authentication of digital signatures.

3. 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.

4. CAs are considered 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.

Digital Certificates - Reading

1. A Digital Certificates is a public key used to cryptographically link ownership of a public key. This an electronic document that is used when communicating over the internet, and allows you to confirm the identity of the sender. It contains a key which secures the exchange of information over the internet.

2. The difference between the digital certificate and public key is that digital certificate is an electronic document that proves ownership of the public key ( data that is encrypted with the public key) and can be decrypted only by a private key. Conversely, data that has been encrypted with a private key can only be decrypted with the corresponding public key.

3. The most common use case for digital certificates is prove of ownership of the public key.Only the correct public key in a valid certificate will work with the corresponding private key that is owned by the person or device identified by the certificate.

4. A Certificate Authority (CA) issues certificate of proof of ownership of a public key. The certificate issued by CA binds a public key to the name of a person or server. It validates the connection and prevents the use of false public keys.

1. What is a digital certificate?
Its a certificate which makes the link between the ownership of a public key with the entity that owns it. They are used for encryption and authentication.
A digital certificate contains……

• public key being certified
• information about the entity who owns the public key,
• metadata about the digital certificate
• digital signature of the public key created by the creator of the certificate

2. What is the difference between a digital certificate and a public key?
The public key is just one part of the digital certificate. A certificate verifies that an entity is the owner of a particular public key.

3. What is the most common use case for digital certificates?
Initializing secure connections between a web browser and a web serve and for encryption and authentication.

4. What is a certificate authority?
A trusted third party who issues digital certificates

1- What is a digital certificate?
A cryptographic link between a public key and the identity of the owner.

2- What is the difference between a digital certificate and a public key?
A public key is just that – a public key. It has no verifiable link to an owner.

3- What is the most common use case for digital certificates?
Initializing secure connections between web browsers and web servers.

4- What is a certificate authority?
A third party trusted to issue digital certificates.

1. 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. 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;
3. 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;
4. the vast majority of digital certificates are issued by a certificate authority (CA). CAs are considered 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.

1. A digital certificate is a public key certificate that is used to cryptographically link the owner and public key. Digital certificates are used for sharing public keys and authentication.

2. The difference between a digital certificate and a public key is that a digital certificate is cryptographically linked to the owner, a public key is not.

3. The most common case for digital certificates is creating a secure SSL connection between web browser and server.

4. A certificate authority is a trusted third party that issues digital certificates and public keys.

[BlockchainAnarchist]

1. A digital certificate cryptographically links a public key with the entity who owns it.

2. Digital certificates include the public key, identifying information about the entity that owns the public key, related metadata and a digital signature of the public key.

3. The most common use-case for digital certificates are for opening secure SSL connections between web browsers and web servers.

4. Certificate authorities are trusted third-parties. Using a CA enables individuals to extend their trust in the CA to the digital certificates that the CA issues.

• What is a digital certificate?
  • aka: “public key certificate”
  • they’re used to link a public key w/the owner
• What is the difference between a digital certificate and a public key?
  • Digital certificates are for sharing public keys to be used for encryption and authentication
  • It seems that digital certificates gives one the authority to share public keys, but digital certificates are not public keys themselves
• What is the most common use case for digital certificates?
  • They’re used by all major web browser to ensure the integrity of published data n content
• What is a certificate authority?
  • Trusted third parties in charge of issuing digital certificates

1. It is a public key certification and used to cryptographically link ownership of a public key with the entity that owns it.
2. The digital certificate uses the public key to identify the data’s source, while the public key is part of an digital signature (electronic document that uses the public key to verify the data’s integrity - identity).
3. The most common use is to link a webserver for a domain that is owned either by an individual or an organization.
4. A certificate authority is a third party that issues digital cerftificates.

Also known as public key certificate , is a proof of an ownership of a public key as an electronic document
2,
From my understanding they are definitely not the same thing so everything is different between them. Please correct me
