23/09/2016 · The OpenSSL team announced the release of version 1.0.2j, which patches a missing CRL sanity check issue affecting only version 1.0.2i. As a result any attempt to use CRLs in OpenSSL 1.0.2i will crash with a null pointer exception. (CVE-2016-7052) To update to the new OpenSSL version, please follow the instructions in our documentation system.

15/09/2017 · Testing OCSP with Openssl. I had been working on an implementation that uses this OCSP Stapled response. The use case was that connected device makes a request to server over TLS. The device presents a client cert to authenticate itself to the server. The 8 thoughts on “ How to do OCSP requests using OpenSSL and CURL ” Pingback: Measuring OCSP Responder Performance with Powershell. John July 28, 2013 at 12:59 pm. Thank you! Reply ↓ Peter Hesse June 27, 2018 at 12:51 pm. Thanks, this is helpful. I’m This requires me to setup a OCSP responder. Since it will only be used for testing I assume that the minimal implementation provided by OpenSSL should suffice. I have extracted the a certificate from a cable modem, copied it to my PC and converted it to the PEM format. Now I want to register it in the OpenSSL OCSP database and start a server. In openssl errors i found this define - x509_err_ocsp_verify_needed, but i don't understand how it uses. It seems that may be exists some kind of callback for my connecting to ocsp server function or something like that. Also i found it which i can use, as i understand, for my own validate function, but i want only ocsp check.

16/03/2019 · Kurt, since OCSP stapling per RFC 6066, relates only to the client checking server certificate OCSP status, the OpenSSL API below probably relates to server certificate OCSP status only. SSL_get_tlsext_status_exts() SSL_set_tlsext_status_ocsp_resp() So I would not enhance the stapling code currently. Originally I wanted to add the API for the

3/03/2015 · These are quick and dirty notes on generating a certificate authority (CA), intermediate certificate authorities and end certificates using OpenSSL. It includes OCSP, CRL and CA Issuer information and specific issue and expiry dates. We'll set up our own root CA. We'll use the root CA to generate an example intermediate CA. We'll use the Per OpenSSL's OCSP man page, running their OCSP server is benefitial for test and demo purposes and is not recommended for production OCSP responder use. Other PKI vendors have more robust OCSP management capabilities integrating into CMS web solutions. Since most clients carry on with a certificates duty if OCSP is unavailable this shouldn't concern us for testing purposes. If you want to 16/03/2019 · Kurt, since OCSP stapling per RFC 6066, relates only to the client checking server certificate OCSP status, the OpenSSL API below probably relates to server certificate OCSP status only.

As is usually the case with SSL, the best approach is to use OpenSSL for troubleshooting.

I then encrypted the private key itself using regular mcrypt with the human-memorizable key of my choice and converted it to ACSII using base64_encode.
