I'm implementing an OCSP server to answer OCSP requests for my custom CA. I already implemented the invalidation of leaves certificates, with the intermediate CA certificate signing the OCSP response, and it seems to be working. However, I have troubles implementing the OCSP response to invalidate a intermediate certificate.

The entry point for the OpenSSL library is the openssl binary, usually /usr/bin/openssl on Linux. The general syntax for calling openssl is as follows: $ openssl command [ command_options ] [ command_arguments ] Alternatively, you can call openssl without arguments to enter the interactive mode prompt. 24/09/2019 · Once done, a request to the OCSP server can be sent by running the following command: openssl ocsp -no_nonce -issuer intermediate.crt -cert cert.crt -url [OCSP_URI] -VAfile intermediate.crt *where cert.crt is the end-entity certificate issued to your domain/subdomain and intermediate.crt is the first intermediate certificate mentioned above module OpenSSL::OCSP OpenSSL::OCSP implements Online Certificate Status Protocol requests and responses.. Creating and sending an OCSP request requires a subject certificate that contains an OCSP URL in an authorityInfoAccess extension and the issuer certificate for the subject certificate. 6/11/2013 · Since the OCSP responder certificate has the 'OCSP no revocation checking' extension, the certificate is not verified, even when OCSP is forced to validate against the OPENSSL trustpoint. By default, all trustpoints are searched when the ASA is trying to verify the user certificate. OpenSSL::OCSP implements Online Certificate Status Protocol requests and responses.. Creating and sending an OCSP request requires a subject certificate that contains an OCSP URL in an authorityInfoAccess extension and the issuer certificate for the subject certificate. openssl x509 -noout -ocsp_uri -in extracted.crt.pem I dug through the source code of openSSL to see how it prints this information. I found the function X509_get1_ocsp() which returns STACK_OF(OPENSSL_STRINGS). This piece of code prints the URL without any hassle :

Later, the alias openssl-cmd(1) was introduced, which made it easier to group the openssl commands using the apropos(1) command or the shell's tab completion. In order to reduce cluttering of the global manual page namespace, the manual page entries without the 'openssl-' prefix have been deprecated in OpenSSL 3.0 and will be removed in OpenSSL 4.0. 12/09/2018 · This is to give an idea of how to set up OpenSSL to use OCSP. We will look into how to generate certificates, get their OCSP response from the created OCSP server and also we’ll see how to 4/07/2014 · This article shows you how to manually verfify a certificate against an OCSP server. OCSP stands for the Online Certificate Status Protocol and is one way to validate a certificate status.
