If the client does not receive a stapled response, it will just contact the OCSP server by itself. [4] However, if the client receives an invalid stapled response, it will abort the connection. [ 1 ] The only increased risk of OCSP stapling is that the notification of revocation for a certificate may be delayed until the last-signed OCSP ...
The OCSP responder uses the certificate serial number to look up the revocation status of Alice's certificate. The OCSP responder looks in a CA database that Carol maintains. In this scenario, Carol's CA database is the only trusted location where a compromise to Alice's certificate would be recorded.
OCSP suffers from scalability issues. It relies on the client having network access at the time of checking the certificate's revocation status; further, the OCSP responder must be accessible and produce usable responses, or else the check will fail and the client must choose between failing-soft and failing-hard.
A server uses it to deliver to the client (e.g. a web browser) a set of hashes of public keys that must appear in the certificate chain of future connections to the same domain name. For example, attackers might compromise a certificate authority, and then mis-issue certificates for a web origin. To combat this risk, the HTTPS web server serves ...
The most common reason for revocation is the user no longer being in sole possession of the private key (e.g., the token containing the private key has been lost or stolen). Hold This reversible status can be used to note the temporary invalidity of the certificate (e.g., if the user is unsure if the private key has been lost).
IIS Express, a lightweight (4.5–6.6 MB) version of IIS, is available as a standalone freeware server and may be installed on Windows XP with Service Pack 3 and subsequent versions of Microsoft Windows. IIS 7.5 Express supports only the HTTP and HTTPS protocols.
The current Windows user information on the client computer is supplied by the web browser through a cryptographic exchange involving hashing with the Web server. If the authentication exchange initially fails to identify the user, the web browser will prompt the user for a Windows user account user name and password.
403.15 – Client Access Licenses exceeded; 403.16 – Client certificate is untrusted or invalid; 403.17 – Client certificate has expired or is not yet valid; 403.18 – Cannot execute request from that application pool; 403.19 – Cannot execute CGIs for the client in this application pool; 403.20 – Passport logon failed; 403.21 ...
