Digital Certificates and Secure Web Accessbluntm64
Digital certificates provide a more robust way to authenticate users to websites than usernames and passwords. With certificates, users need both the certificate and a password to access a site, increasing security. Passwords are never sent over the web, and administrators do not have access to user passwords. Certificates also allow users to digitally sign documents and access multiple sites with a single identity. Implementing certificates involves obtaining certificates from a certificate authority and configuring web servers and applications to support certificate-based authentication.
A digital certificate is a unique electronic document that identifies an individual or organization. It uses public key infrastructure (PKI) to allow secure data exchange over the internet. A digital certificate contains a public key and is digitally signed by a certificate authority (CA) that verifies the identity of the requester. When user A sends a message to user B, user B can verify user A's certificate by checking the CA's digital signature on the certificate using the CA's public key. Digital certificates are important for secure communication, online banking, expanding e-commerce, and protecting against online threats. The major types are SSL certificates for servers, code signing certificates for software, and client certificates for identifying individuals.
Digital signatures and digital certificates provide authentication for online transactions, allowing users to verify their identity and detect unauthorized modifications to documents. Certificate authorities are trusted third parties that issue and manage digital certificates. Root certificates identify the top certificate authority and are used to validate other certificates in the chain. Client and server certificates contain identifying information and allow authentication between applications instead of usernames and passwords.
Digital certificates certify the identity of individuals, institutions, or devices seeking access to information online. They are issued by a Certification Authority which verifies the identity of the certificate holder and embeds their public key and information into the certificate. Digital certificates allow for secure online transactions by providing identity verification, non-repudiation of transactions, encryption of communications, and single sign-on access to systems. They are commonly used in applications that require authentication and encryption like SSL, S/MIME, SET, and IPSec.
This document summarizes digital certificates. It defines a digital certificate as an attachment to an electronic message used for security purposes, similar to IDs like a driver's license. It discusses key terms like encryption, decryption, public and private keys. It describes the content and types of digital certificates. It also explains the role of certification authorities in issuing certificates and validating identity. The process of obtaining a certificate involves applying to a CA, who verifies identity and issues a certificate containing the applicant's public key. Digital certificates provide advantages like authentication, integrity, confidentiality and access control for network communications. Many enterprises have found deploying digital certificate systems necessary to support growing networks and remote access.
Public key infrastructure (PKI) uses public and private key cryptography and digital certificates to provide security services like authentication, non-repudiation, and data integrity. A PKI system uses certification authorities to validate users' identities and issue digital certificates that bind public keys to those identities. These certificates allow users to securely exchange information and digitally sign documents online through services like SSL/TLS and S/MIME. Smart cards can serve as portable devices for storing users' private keys and certificates to enable strong authentication on untrusted devices.

Introduction to Public Key InfrastructureTheo Gravity
Adonis Fung and I worked on a project where we defined and built PKI (Public Key Infrastructure) for our local development and deployed environments. I gave a talk to our engineers on how PKI works, covering encryption, signing, trust stores, and how the HTTPS handshake works.
PKI is a set of components needed to issue and manage digital certificates. It includes hardware, software, policies and people. Certificates contain a subject's public key and are digitally signed by a certificate authority. PKIs can be public, where any system can validate certificates, or private, where only an organization's systems participate. Building a private PKI requires designing certificate templates and revocation processes. Managing certificates involves enrollment methods and checking certificate status.

Presentation on digital signatures & digital certificatesVivaka Nand
Digital signatures and digital certificates use public key cryptography to authenticate users and verify the integrity of digital documents. A digital signature is created by encrypting a document with a user's private key. Anyone can then decrypt the signature using the signer's public key to verify that the document came from the correct user and has not been altered. Digital certificates contain a user's public key and identification information, and are digitally signed by a Certificate Authority to validate the certificate. Common uses of digital signatures and certificates include encrypting messages, authenticating users, and facilitating secure online transactions.
This document discusses certificate authorities (CAs) and provides an example scenario for securing a web server using a CA. It defines a CA as an entity that issues digital certificates for use by other parties in public key infrastructure schemes. There are commercial CAs, as well as CAs run by institutions and governments. The document then describes the process a CA goes through to issue a certificate and how users can verify certificates. It provides a list of common CAs. Finally, it presents a scenario where a web server obtains a server certificate from a CA to secure its SSL port, and clients can obtain client certificates from the CA's website to access the secure site.
Digital certificates are used for security and verification purposes when sending electronic messages. A sender applies for a digital certificate from a Certificate Authority containing their public key and identification. The recipient can then use the CA's public key to decode the attached certificate and verify the sender's identity and public key to encrypt a reply message.
The document discusses various aspects of securing e-commerce networks. It describes digital certificates which serve to verify identity and are issued by a certification authority. There are four main types of digital certificates. The document also discusses selecting network security technologies based on principles like defense in depth.

This document discusses PKI (Public Key Infrastructure) and OpenSSL. It defines PKI as a structure that authenticates users and services to ensure secure information exchange. PKI uses digital certificates issued by Certificate Authorities to associate public keys with certificate owners. OpenSSL is an open source implementation of SSL/TLS that is used to set up and manage PKI environments through commands like generating certificate requests and certificates, revoking certificates, and creating CRLs (Certificate Revocation Lists). The document provides examples of OpenSSL commands for performing common PKI tasks.
Digital certificates allow for secure electronic communication and transactions over the internet. There are three main types of digital certificates: secure socket layer (SSL) certificates, code signing certificates, and client certificates. SSL certificates secure credit card transactions and login information on a website using encryption. Code signing certificates digitally sign software to authenticate that it comes from the claimed publisher. Client certificates contain information about a client that allows a server to identify and authenticate the client during a secure session. Digital certificates are issued by certificate authorities to facilitate secure e-commerce and internet communication using public key infrastructure (PKI) technology.
