kandi X-RAY | ocsp Summary
To check if a certificate is valid, we need to know an URL, provided by the authority that issued the certificate, that can be called to check if the certificate has been revoked. This URL may be included in the HTTPS certificate itself.

QUESTION
I'm trying to secure a Java Spring Boot REST service with Keycloak. Part of that involves communication between the service and Keycloak to get the well-known OpenID configuration.
When everything is unencrypted (over HTTP), things work fine. When I add an SSL certificate into the mix (technically on an nginx server in front of both services), I'm getting an SSL handshake error.
If I hit the REST service or Keycloak directly with my browser, there's no SSL error reported by the browser. Using curl from the rest server machine to the Keycloak machine looks fine as well, and I've tried having nginx force a TLS 1.2 or 1.3 response.
The error when the actual REST service tries to hit the Keycloak service looks like:

I'm working on pdf signatures using itext7 and currently need to support all PAdES signature levels: B-B, B-T, B-LT, B-LTA https://ec.europa.eu/digital-building-blocks/wikis/display/ESIGKB/What+are+the+B-T-LT+and+LTA+levels+of+an+electronic+signature
My problem is how i can create B-LT signature with itext? I have created B-B and B-T with this code:
...ANSWER
Answered 2022-Mar-04 at 20:25Looks about right. The only material difference between PAdES-B-LT and PAdES-B-LTA is that the signature validation data needs to be timestamped as well. As such, to go from PAdES-B-LT to PAdES-B-LTA, it suffices to add a document timestamp.
With iText, that more or less works like this:

I have an API that creates Base64 digest of a PDF Document. Now I want to create another API that takes this digest and PFX and creates an ETSI.CAdES.detached signature and takes LTV informations(Certs chain,OCSP response,CRL) that I want to embed in my PDF to obtain a PAdES-LTV signature using 3rd API(My 3rd API will take CAdES signature and LTV informations obtained from this API and will embed them in my PDF).I dont know how to create this ETSI.CAdES.detached signature using that digest and a PFX with Java and Bouncy Castle.I try to follow this github tutorial.
...ANSWER
Answered 2022-Mar-03 at 18:45As you have declared, you have your own code for preparing a PDF for signing and for injecting the signature container into it. Thus, your question essentially burns down to
Implementation in the iText 7 Signing FrameworkHow to create a CAdES signature container with BouncyCastle that can be used to create a PAdES BASELINE B or T PDF signature?
As I do not have your existing code, I had to use a different framework for my tests. I used the iText 7 signing framework for that.
BouncyCastle does contain a CMSSignedDataGenerator to generate CMS signature containers.
The default implementation of the SignerInfo generation therein unfortunately is not CAdES/PAdES compatible as it does not create signed ESSCertID[v2] attributes. Fortunately, though, the implementation is designed to allow plugging in custom attributes sets.
Thus, you can create the CAdES containers required for PAdES BASELINE signatures with a customized CMSSignedDataGenerator.
So when you have prepared the PDF for signing, you can proceed like this:
QUESTION
I'm trying to validate a certificate path with stapled OCSP checking through CertPathValidator. There might be some RFC-protocol that prohibits what I expect to validate just fine, but I've been unable to find this.
Some paint art to describe relations between certificates discussed: overview
When verifying the certificate path I get an exception stating that the responder is not authorized to sign OCSP responses.
CertPathValidatorException: Responder's certificate is not authorized to sign OCSP responses
This is due to sun.security.provider.certpath.OCSPResponse:561. The checks leading to this outcome expect the certificate used to sign the OCSP response (or its issuer) to be the same as the one issuing the certificate of the signature we are verifying.
This is however not the case here. OCSP responders certificate has extended key usage for OCSP-signing, should it not be able to sign OCSP responses when there is an intermediate between the CA and signers certificate?
...ANSWER
Answered 2022-Feb-21 at 07:58If you stumble upon the same problem;
I added the responding certificate for the OCSP to PKIXRevocationChecker.setOcspResponderCert() after validating that it originates from the root CA or is the root CA. The revocation checker will still validate that the responding certificate has the proper extensions to sign OCSPs.
QUESTION
I created a simple Python program to get the expiry date of SSL cert, from reference on the Internet. It works correctly for cert that is still not expired. But for cert that already expired, an error was raised during the socket handshake due to the cert expiry.
How do I get the expired cert info to extract the expiry date because the connection is refused. Is there a way to force the socket connection to establish even though the cert might be expired?
Code:

QUESTION
I'm having some trouble installing the python cryptography package on my raspberry pi, specifically with python version 3.9.8 (installed with pyenv). The cryptography package is installed on my system using pacman (python-cryptography package), and thus works using the main python interpreter (3.10.1). However, I need some version of python 3.9 specifically for another package I am using in this project. Any time I try to install cryptography through the python 3.9.8 environment, I get the following error:
ANSWER
Answered 2022-Jan-14 at 19:59@jakub's solution ended up solving the problem for me. I uninstalled the version of rust that was installed through pacman. To replace it, I installed rustup and then using rustup, installed the latest nightly version of rust (1.60). Once I did that, installing the cryptography package worked just fine.
If you are using rustup, just make sure that you add ~/.cargo/bin to your PATH before installation. Also, the command I used to install rust through rustup was rustup toolchain install nightly.
QUESTION
Nifi v1.15.2 use https and authentication by default whereas it was not the case for older version of Nifi for example v1.13.2.
I want to configure nifi v1.15.2 using http and without authentication
I think i have to modify one of these properties but i don't really know which ones
below the initial configuration
ANSWER
Answered 2022-Jan-07 at 15:52To remove authentication, one would need to do what was done for the configuration of NiFi pre-1.14.0, as with 1.14.0 "NiFi now starts up in a mode enabling security features by default. This means NiFi starts up with HTTPS only now instead of HTTP and it requires a specific auto generated username and password to login or the user can explicitly set the username and password which will be used via the provided toolkit. Gone are the days of firing a default NiFi and it is accessible via HTTP without authentication." https://cwiki.apache.org/confluence/display/NIFI/Release+Notes#ReleaseNotes-Version1.14.0
Of course, the values of "nifi.web.http.host= and nifi.web.http.port=" need to be set. I would also consider changing the keystore and truststore values, plus nifi.security.user.authorizer as well to blank.
If this all doesnt work, what I would recommend is downloading Nifi 1.13.2 and trying to see if using the nifi.properties that it has by default will work in NiFi 1.15.2. This is the best start.
If this answer has assisted you in solving the issue, please feel free to accept this answer as the solution.

I have a server running Ubuntu 20.04, nginx and varnish with letsencrypt SSL.
I have installed PHPMyAdmin to the default server block and have another server block for my actual website running magento 2.4.3. This was all working fine until i installed varnish and now when trying to load either site i get the 503 Backend fetch failed error and when i try and load then on port 8080 from the URL i get a "this page cannot be reach" error.
I have configured nginx to listen on port 8080 for both sites, i have set varnish to listen on port 80. I have edited the vcl generated by magento to set the host and port to 127.0.0.1 and 8080 respectively as shown on https://devdocs.magento.com/guides/v2.4/config-guide/varnish/config-varnish-configure.html.

Install ocsp
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
