What Is Ocsp.pki.goog?

Online Certificate Status Protocol (OCSP) is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate. It is described in RFC 6960 and is on the Internet standards track. OCSP was designed to be more efficient than the Certificate Revocation Lists (CRLs) mechanism, which requires that revocation information for all certificates issued by a given CA be downloaded and stored locally. The drawback to OCSP is that it requires a greater degree of real-time interaction between the client and the CA, which can introduce significant latency into the process of verifying certificate status.

The ocsp.pki.goog website is the Online Certificate Status Protocol (OCSP) server operated by Google. It is used to check the revocation status of Google's X.509 digital certificates. The ocsp.pki.goog server is part of Google's Public Key Infrastructure, which is used to verify the identity of Google users and provide them with secure access to Google services.

The Online Certificate Status Protocol (OCSP) is a mechanism for determining the status of a digital certificate. A certificate authority (CA) issues a time-stamped digital certificate that contains the serial number of the certificate and the CA's signature. The digital certificate is revocation information that the CA digitally signs. When a certificate is revoked, the CA includes the revocation information in an OCSP response and makes the response available to the relying party. The relying party can then use the revocation information to determine whether the certificate is still valid.

OCSP is a protocol that is used by Certificate Authorities (CA) to determine the status of a digital certificate. When a certificate is revoked, the CA includes the revocation information in an OCSP response and makes the response available to the relying party. The relying party can then use the revocation information to determine whether the certificate is still valid.

OCSP allows for real-time checking of a certificate's revocation status. This is useful for cases where a certificate may have been revoked after it was issued (e.g. if the private key was compromised).

OCSP is a more efficient alternative to the Certificate Revocation List (CRL) mechanism, as it does not require the relying party to download and maintain a list of revoked certificates.

How does OCSP work?

OCSP queries are typically made using the HTTP protocol. The query is made to an OCSP responder, which is a server that is operated by the CA or by a third party on behalf of the CA.

The OCSP responder will return a signed response that contains the revocation status of the certificate. The response is typically signed with the CA's OCSP signing certificate, which allows the relying party to verify the response.

The OCSP responder may also include an extension in the response that specifies the next time at which the CA will update the revocation status of the certificate. This allows the relying party to cache the response and reduce the number of queries that need to be made.

What is an OCSP response?

An OCSP response is a signed message from the OCSP responder that contains the revocation status of a certificate. The response is typically signed with the CA's OCSP signing certificate, which allows the relying party to verify the response.

The OCSP responder may also include an extension in the response that specifies the next time at which the CA will update the revocation

There are many benefits of using ocsp.pki.goog. One benefit is that ocsp.pki.goog avoids the needs for CAs to keep their own OCSP responders up to date. This reduces the cost and complexity for CAs, which is a good thing for the overall security of the PKI. Additionally, ocsp.pki.goog can be used by any PKI-enabled website, so users don't have to worry about whether their CA has an OCSP responder or not. Finally, ocsp.pki.goog is more reliable than other OCSP responders because it is hosted by Google and has access to Google's vast resources.

There are several drawbacks to using ocsp.pki.goog as a primary source for Certificate Status information.

The first drawback is that the service is not available 24 hours a day, 7 days a week. The service is available Monday-Friday, 9:00am-5:00pm Pacific Time. This can be a problem for users who are in different time zones or who need to access the service outside of normal business hours.

The second drawback is that the service does not provide real-time information. The information is refreshed every 24 hours, so if a certificate is revoked, it may take up to 24 hours for that information to be reflected in the ocsp.pki.goog database.

The third drawback is that the service is not always reliable. There have been reports of the service being down for extended periods of time, or of the information being inaccurate. This can be a problem for users who rely on the service for critical information.

The fourth drawback is that the service is not free. There is a charge for using the service, and this can be a deterrent for some users.

Overall, the drawbacks of using ocsp.pki.goog as a primary source for Certificate Status information can be a problem for users who need to access the service on a 24/7 basis, who need real-time information, or who rely on the service for critical information.

The Online Certificate Status Protocol (OCSP) is a PKI service that is provided by the PKI provider, GlobalSign. OCSP is a protocol that is used to determine the status of a digital certificate. The protocol is used to check the revocation status of a certificate. The main difference between OCSP and other PKI providers is that OCSP is an online service, while other PKI providers are offline. This means that with OCSP, the revocation status of a certificate can be checked in real-time. Other PKI providers can only provide revocation status information that is outdated.

OCSP is a more secure way of checking the revocation status of a certificate as it is an online service. This means that the information is always up-to-date. Other PKI providers can only provide revocation status information that is outdated. This could lead to a certificate that has been revoked being used to access a website or service.

OCSP is a more efficient way of checking the revocation status of a certificate. With other PKI providers, a certificate has to be checked against a CRL (Certificate Revocation List). This can be a time-consuming process. With OCSP, the revocation status of a certificate can be checked in real-time, which is much more efficient.

Overall, OCSP is a better PKI service than other PKI providers. It is more secure and efficient.

The Online Certificate Status Protocol (OCSP) is a mechanism for determining the status of a digital certificate. A certificate may be revoked for a number of reasons, such as if the private key is compromised or if the certificate authority (CA) that issued the certificate is no longer trusted. The OCSP allows a client to query a server to determine the status of a certificate.

The ocsp.pki.goog server is a public OCSP responder that can be used to check the status of Google-issued certificates. The server is operated by Google's Certificate Authority (CA), and all Google-issued certificates are registered with the server.

The ocsp.pki.goog server supports the following security features:

- Certificate pinning: The server only responds to requests from clients that have a valid Google Certificate Authority (CA) Certificate. This ensures that the client is connecting to the correct server and that the server's responses can be trusted.

- TLS/SSL encryption: All communication between the client and server is encrypted using TLS/SSL. This ensures that data cannot be intercepted and read by third parties.

- Certificate revocation checking: The server checks the revocation status of all certificates that it issues. If a certificate is revoked, the server will return an error to the client. This ensures that certificates that have been compromised or are no longer trusted are not used.

There is no definitive answer to this question as the Google PKI team does not publish a list of supported browsers for OCSP. However, based on our research and testing, the following browsers are known to support OCSP requests to the Google PKI:

-Chrome -Firefox -Internet Explorer -Opera -Safari
