Digital Certificates - Reading Assignment

[illyushin]

Used for linking ownership of a public key to the entity that owns it, also called public key certificate

A public key can be owned by someone and used in combination with his private key, but the public key certificate is there to link this ownership

They are 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

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

[Kieran]

1. A Digital Certificate is an ‘electronic credential’ mechanism of linking or authenticating the ownership of a public key with the person or entity that owns that public key.

2. A Public Key is shared by using a Digital Certificate. So the difference is that a digital certificate ‘contains’ the public key, as well as other data, such as the identity of the owner/issuer.

3. Digital Certificates are most often encountered when using websites - to authenticate, behind the scenes, that a site is owned and operated by who is registered as doing so. In this way, you can trust the authenticity of the site you are visiting.

4. A Certificate Authority is a trusted third party organisation that issues certificates, and can verify those certificates.

Intro to Digital Certificates

[Alexander_Scholten]

1. What is a digital certificate?
Also known as a public key certificate, is used to link the owner of a public key with the entity that owns the certificate.
2. What is the difference between a digital certificate and a public key?
A digital certificate shares public keys and a public key encrypts data.
3. What is the most common use case for digital certificates?
A digital signature which depends on a public key shared by a digital certificate to be trusted. Another use case is for securing SSL connections between web browsers and web servers.
4. What is a certificate authority?
It is a trusted third party that issues digital certificates in the PKI context.

1. What is a digital certificate?
   A digital certificate cryptographically links the public key to its owner.

2. What is the difference between a digital certificate and a public key?
   A digital certificate contains the public key but also other elements such as the name of the owner/entity and a digital signature.

3. What is the most common use case for digital certificates?
   To authentificate the owner of the public key or to initiate secure SSL connections between web browsers and servers.

4. What is a certificate authority?
   A trusted third party issuing the certificate.

[Littlejohn137]

1. Digital certificates are similar to identity or public key certificates used to prove ownership.
2. Digital certificates are public keys with additional metadata attached.
3. Digital certificates are commonly used for initializing secure SSl connections between web browsers and web servers.
4. A certificate authority is a validator who certifies the digital identities of individuals online.

[MichaelGolpe]

1. 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.
2. A public key is used for the 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. Web browsers and servers to assure data integrity.
4. A trusted third party that issues the certificates through PKI

[Raulitiu]

1. What is a digital certificate?
   A digital certification os a public key certificate.

2. What is the difference between a digital certificate and a public key?
   Digital certificates are for sharing the public keys to be used for encryption and autentification. Digital certificates includes public key being certified.

3. What is the most common use case for digital certificates?
   They are most commonly used for initializing secure SSL connections between web browsers and web servers.

4. What is a certificate authority?
   Certificate authority are trusted third parties in the context of a PKI

[Luca_del_Grosso]

1.A digital certificate connects a public key with the owner of that public key.

2.The difference between digital certificate and a public key is mainly about identities because the digital certificate contains the informations of the public keys’es owner , when public keys itself encrypts informations.

3. The most use case of digital certificates is to control the identity of the owner and to guarantee the safety of the public key.

4.Certificate Authorities (CAs) are trusted 3rd parties that issue the digital certificates.

[Jimo]

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

2. Digital certificates include the public key being certified. Digital certificates also identifying information about the entity that owns the public key, metadata relating to the digital certificate and a digital signature from who created the public key.

3. They are most commonly used for initializing secure connections between web browsers and web servers. Digitalk certificates provide assurance that published content has not been modified by any unauthorized actor.

4. It’s a trusted third party that issue digital certificates.

[SalJoaNoc]

[1. It is used to cryptographically link ownership of a public key with the entity that owns it.
2. The difference is that a digital certificate shares public keys and a public key encrypts data.
3. To provide assurance that published content has not been modified by any unauthorized actors, and to share keys for encrypting and decrypting content.
4. A certificate authority is an established/trusted entity that provides the certificates.

[Luca86R]

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

2. Digital certificates include the public key and metadata relating to the digital certificate of the public key created by the issuer of the certificate. Public Key is a cryptograhpy signature to prove the owner of a private key.

3. Digital certificates are used for create a secure SSL connection between web browsers and and web servers.

4. it is trusted third-part authority that 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.

2- The difference is that 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- Digital certificates are used in public key cryptography functions; they are most commonly used for securing connections between web clients and web. Digital certificates are also used for sharing keys to be used for public key encryption and authentication of digital signatures. Digital certificates provide assurance that published content has not been modified by any unauthorized actors.

4- They are responsible for issuing most of the digital certificates, they are trusted third parties.

1. What is a digital certificate? A digital certificate is an electronic document used to prove the ownership of a public key. It is also known as a public key certificate.
2. What is the difference between a digital certificate and a public key? A digital certificate contain all the information about the public key. A public key is part of a cryptographic system that uses asymmetric encryption algorithms to convert information into an unreadable format.
3. What is the most common use case for digital certificates? For creating secure websites where e-commerce is used. The digital certificate is usually issued by a trusted 3rd party and provides a secure internet connection (SSL - secure sockets layer) between the web browser (usually the customer) and web server (usually the vendor). This allows the customer to confidently provide personal and/or credit card information and also expect privacy in the transaction.
4. What is a certificate authority? A trusted 3rd party authority who issues digital certificates. They do this by first validating the identity of the entity requesting the certificate. They look at the specific people involved in the request including their email addresses, websites, and other tradition documentation, etc. Once validated they then bind the entity to cryptographic keys through the digital certificate.
