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]
Most browsers disable pinning for certificate chains with private root certificates to enable various corporate content inspection scanners [6] and web debugging tools (such as mitmproxy or Fiddler). The RFC 7469 standard recommends disabling pinning violation reports for "user-defined" root certificates, where it is "acceptable" for the ...
Browsers and other relying parties might use CRLs, or might use alternate certificate revocation technologies (such as OCSP) [4] [5] or CRLSets (a dataset derived from CRLs [6]) to check certificate revocation status. Note that OCSP is falling out of favor due to privacy and performance concerns [7] [8] [9]. Subscribers and other parties can ...
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.
A security key is a physical device that gets uniquely associated with your AOL account after you enable it. Each time you sign in with your password, you'll be prompted to approve access to your account using your key. This prevents anyone who doesn't have your security key device from gaining access to your account.
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.
