Since an OCSP response contains less data than a typical certificate revocation list (CRL), it puts less burden on network and client resources. [10] Since an OCSP response has less data to parse, the client-side libraries that handle it can be less complex than those that handle CRLs. [11]
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 ...
Certificate revocation is "an important tool" for dealing with attacks and accidental compromises. RFC 9325 places a normative requirement on TLS implementations to have some means of distrusting certificates. [9] Without revocation, an attacker can use a compromised certificate to impersonate its owner until expiry. [4]
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).
In Mozilla Firefox on Windows operating systems, the names of the domains/websites to which the authentication is to be passed can be entered (comma delimited for multiple domains) for the "network.negotiate-auth.trusted-uris" (for Kerberos) or in the "network.automatic-ntlm-auth.trusted-uris" (NTLM) Preference Name on the about:config page.

A server implements an HSTS policy by supplying a header over an HTTPS connection (HSTS headers over HTTP are ignored). [1] For example, a server could send a header such that future requests to the domain for the next year (max-age is specified in seconds; 31,536,000 is equal to one non-leap year) use only HTTPS: Strict-Transport-Security: max-age=31536000.
Couldn't find the user in time. The server could not produce a response within a suitable amount of time, for example, if it could not determine the location of the user in time. The client MAY repeat the request without modifications at any later time. [1]: §21.4.9 409 Conflict User already registered.
Security Support Provider Interface (SSPI) is a component of Windows API that performs security-related operations such as authentication.. SSPI functions as a common interface to several Security Support Providers (SSPs): [1] A Security Support Provider is a dynamic-link library (DLL) that makes one or more security packages available to apps.
