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 ...
In public key infrastructure (PKI) systems, a certificate signing request (CSR or certification request) is a message sent from an applicant to a certificate authority of the public key infrastructure (PKI) in order to apply for a digital identity certificate. The CSR usually contains the public key for which the certificate should be issued ...
IIS 8.0 is only available in Windows Server 2012 and Windows 8. IIS 8.0 includes SNI (binding SSL to hostnames rather than IP addresses), Application Initialization, centralized SSL certificate support, and multicore scaling on NUMA hardware, among other new features. IIS 8.5 is included in Windows Server 2012 R2 and Windows 8.1. This version ...
In more detail, when making a TLS connection, the client requests a digital certificate from the web server. Once the server sends the certificate, the client examines it and compares the name it was trying to connect to with the name(s) included in the certificate. If a match occurs, the connection proceeds as normal.
The metabase is an inheritable, hierarchical database that allows for configuration of HTTP/HTTPS, FTP, SMTP, and NNTP at the server, the site, or the folder or file level. Different versions of IIS use different formats; prior to IIS version 6 this was always a proprietary format, whereas with 6.0 and later the data is stored in XML files.
This class of status code indicates the client must take additional action to complete the request. Many of these status codes are used in URL redirection. [2]A user agent may carry out the additional action with no user interaction only if the method used in the second request is GET or HEAD.
By eliminating payment, web server configuration, validation email management and certificate renewal tasks, it is meant to significantly lower the complexity of setting up and maintaining TLS encryption. [15] On a Linux web server, execution of only two commands is sufficient to set up HTTPS encryption and acquire and install certificates.
RFC 5280 defines self-signed certificates as "self-issued certificates where the digital signature may be verified by the public key bound into the certificate" [7] whereas a self-issued certificate is a certificate "in which the issuer and subject are the same entity". While in the strict sense the RFC makes this definition only for CA ...
