AspEncrypt.com - Crypto 101: Digital Certificates This means that when a certificate from a lower-level CA is passed along with the encrypted message, all of the certificates in its chain of trust up to the root should be passed along with it. When the CA receives a certificate request it extracts a person's name and public key information and performs a certain procedure aimed at verifying that the public key really belongs to the person whose name is included in the certificate request. Certificates can also be revoked, either because the user's key has been compromised, the CA's key has been compromised, or because the CA no longer wants to certify the user. www.aspencrypt.com /crypto101_certs.html   (529 words)

Description of digital certificates   (Site not responding. Last check: 2007-11-07) A digital certificate is an ID that is carried with a file. When a digital certificate is used to sign programs, ActiveX controls, and documents, this ID is stored with the signed item in a secure and verifiable form so that it can be displayed to a user to establish a trust relationship. A digital signature is the public certificate plus the value of the signed data encrypted by a private key. support.microsoft.com /support/kb/articles/Q206/6/37.ASP   (1293 words)

Description of Digital Certificates The main purpose of the digital certificate is to ensure that the public key contained in the certificate belongs to the entity to which the certificate was issued. Digital certificates package public keys, information about the algorithms used, owner or subject data, the digital signature of a Certificate Authority that has verified the subject data, and a date range during which the certificate can be considered valid. Without certificates, it would be possible to create a new key pair and distribute the public key, claiming that it is the public key for almost anyone. support.microsoft.com /support/kb/articles/q195/7/24.asp   (1328 words)

The Chronicle: Information Technology: December 10, 1999 Associated with the certificate is a pair of encryption keys, one private and one public. Most research institutions are not yet issuing digital certificates, however, because publishers of the electronic data bases they subscribe to don't have their servers set up to accept certificates, says Eric F. Celeste, assistant director for technology planning and administration for the Massachusetts Institute of Technology's libraries. Digital certificates are designed to resolve problems like the ones facing the libraries at M.I.T. About three years ago, students and employees at M.I.T. began paying Internet-service providers commercial rates for connections, which in many cases were cheaper that those offered through the institution. chronicle.com /free/v46/i16/16a04701.htm   (1680 words)

The Chronicle: Daily news: 03/23/2000 -- 01 University of Pittsburgh officials who want to expand their use of secure digital certificates for online transactions say they are not going to wait for the rest of the world to do the same. Digital certificates, which are considered to be far more reliable than passwords, are small bits of code that prove a person really is who the person claims to be online. And the Digital Library Federation is conducting similar experiments in using digital certificates to manage access to digital libraries. chronicle.com /free/2000/03/2000032301t.htm   (873 words)

Public key certificate - Wikipedia, the free encyclopedia In cryptography, a public key certificate (or identity certificate) is a certificate which uses a digital signature to bind together a public key with an identity — information such as the name of a person or an organization, their address, and so forth. In X.509 PKI systems, the hierarchy of certificates is always a top-down tree, with a root certificate at the top, representing a CA that is 'so central' to the scheme that it does not need to be authenticated by some trusted third party. A certificate may be revoked if it is discovered that its related private key has been compromised, or if the relationship (between an entity and a public key) embedded in the certificate is discovered to be incorrect or has changed; this might occur, for example, if a person changes jobs or names. en.wikipedia.org /wiki/Digital_certificate   (784 words)

Secure Computing: Digital certificates and certificate authorities   (Site not responding. Last check: 2007-11-07) Public Key Infrastructure (PKI) is built on digital certificates, which are simply a way of distributing public keys to the users who need them and to assist in verifying a public key belongs to who you think it belongs to. A digital certificate is a digitally signed record that binds a user's name to their public key. PKI is a set of technologies and security policies used to issue, revoke, and manage digital certificates and key pairs within a specific organizational structure. www.securecomputing.com /index.cfm?sKey=663   (1620 words)

certificate : Java Glossary Your personal certificates are kept in a file called.keystore, and the publicly distributed root certificates belonging to certificate issuing companies, and other trusted companies are kept in a file called cacerts. Certificates vary in cost depending mainly on how much research the certificate authority does to verify you are really you, and how much information is in the certificate that the authority is attesting is true. If you are passing a certificate to another machine to sign code with, then your exported/imported certificate must contain the private key, or you won't be able to sign code, just verify it. mindprod.com /jgloss/certificate.html   (6105 words)

Digital Certificates for ISA Server 2004 Certificate trust is based on the presence of a root certificate from the CA that issued the certificate. Because there is a cost associated with commercial digital certificates, in a scenario where the secure connections are expected to come from internal corporate clients, we recommend that you set up a local CA and issue your own certificates. Digital certificates are used in a wide variety of scenarios. www.microsoft.com /technet/isa/2004/plan/digitalcertificates.mspx   (7771 words)

CAcert: Digital certificates become free Getting a digital certificate signed by a recognized Certificate Authority--and here I mean a well-known entity embedded in web browsers and other critical places, not a Web of Trust kind of thing or a hub on your LAN--used to be a major expense. Certificate Authorities recognize different levels of assurance, based on how hard it is to get a certificate. Thus, when commercial Certificate Authorities defined a digital certificate as a rare item deserved only by large institutions, they could charge accordingly and the institutions felt privileged to have one. www.onlamp.com /pub/wlg/5142   (1307 words)

The recipient of an encrypted message uses the CA's public key to decode the digital certificate attached to the message, verifies it as issued by the CA and then obtains the sender's public key and identification information held within the certificate. www.webopedia.com /TERM/d/digital_certificate.html   (361 words)
