Digital Certificates - Reading Assignment

[SamEdwards]

What is a digital certificate?
A digital certificate is a cryptographic digital document that proves authenticity. In blockchains, it’s used to prove ownership over a public key.

What is the difference between a digital certificate and a public key?
Public certificates are broader in terms of their information compared to a public key. Public keys are just a cryptographic signature, a public certificates certifies the ownership of a public key, the name of the entity that owns the certificate, and other data related to the ownership of the certificate.

What is the most common use case for digital certificates?
I would say the most common use for digital certificates would certifying the ownership of certain servers or web pages.

What is a certificate authority.
A certificate authority is a trusted third party that issues the digital certificates.

1. Digital certificate is used cryptographically link ownership of a public key with the entity that owns it
2. Digital certificates are for sharing public keys to be used for encryption and authentication. They contain 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 most commonly used for initializing secure SSL connections between web browsers and servers.
4. Certificate Authority are 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 certificate authority to the trustworthiness of the digital certificates that it issues.

1: Digital certificate is a public key that is cryptographically linked to the owner with that public key. They are shared for authentication purposes.

2: Digital certificates are public keys already certified, information about the owner of that public key, metadata relating to that certificate, and digital signature.

3: Used for encrypting and decrypting web content so that it assures it has not tampered with.

4: CA are trusted third parties who issue the digital certificates.

1. What is a digital certificate?
A: A digital certificate (or public key certificate), links cryptographically the ownership of a public key with the entity that owns it. They include the public key being certified, identifying information about the owner of the public key, metadata relating to the digital certificate and a digital signature of the private key.

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

What is a digital certificate?
A digital certificate binds a public key with the entity that owns it. It contains the public key, metadata of the entity (about the domain, the organization if available), and metadata of the Certificate Authority that validated this information, which will also digitally sign the certificate.

What is the difference between a digital certificate and a public key?
The public key itself allow to encrypt messages or to ensure that a certain message was sent by the key owner, but it is anonymous, as it does not have information of its ownership. The digital certificate includes, besides of the key, information about the entity that owns the private key (so, it binds the key with an identity), and it is signed by a central authority, working in a trusted ecosystem.

What is the most common use case for digital certificates?
SSL Certificates for Web Pages, allowing encrypted communication between users and the organization that runs the portal (I refer to the organization, as certificates are used to proof identity. The communication would be still encrypted using a private key without a certificate)

What is a certificate authority?
CAs are the issuers of Digital Certificates, which are trusted organizations that validates information from the certificate applicants such as domain ownership, or a further organization relationship to the domain, before issuing and signing the certificate. This is the common way-to-go in a Centralized IT infrastructure.

1. A digital certificate is tool that can link ownership of a public key with the entity that owns it. It includes the certified public keys, information about the entity that owns the public key, and the metadata of digital signatures relationship.

2. Public key is to decrypt a signature. While a digital certificate is used bind together the public key with the identity.

3. The most common use case for digital certificates is securing connection between web browsers and web servers. It is to prove that the published content has not been modified by any unauthorized users.

4. Certificate authority (CA) issues digital certificates.

1. What is a digital certificate>

A digital certificate is also known as a pubic key certificate. It is used to cryptographically link ownership of a public key with the entity that owns it.

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

The difference between a digital certificate and a public key is that a 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.

A public key is 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. 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 Secure Sockets Layer (SSL) protocol 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. What is a certificate authority?

A certificate authority is considered trusted third parties in context of a (PKI) Public Key Infrastructure, using a trusted third party to issue digital certificates enables individuals to extend their trust in the certified authority to the trustworthiness of the digital certificates that it issues.

1. What is a digital certificate?
   A digital certificate proves a server / nodes identity and allows clients and participants to check the encrypted data and is a verification that it belongs to the original source.

2. What is the difference between a digital certificate and a public key?
   A digital Certificate is issued by the trusted 3rd party, and is issue by the C.A.
   A public key is on the other hand is generated by the private key holder (server) and used to check if the information received belongs to the private key holder; final form of Authentication.

3. What is the most common use case for digital certificates?
   To provide assurance that published content has not been modified by any unauthorized user(s) and to share keys for encrypting and decrypting of internet content and private communications. There are different types of certificates,
   SSL certificates for retailers that handle the credit card information of the customers. They need to make sure that they have connected to a secure website.

4. What is a certificate authority?
   The vast majority of digital certificates are issued by a certificate authority (CA). CAs are considered trusted third parties. A third party that issues the certificate.
