问题 I want to read the contents of a CSR in C#. However, I haven't found any way to do it in C#. What I've found was the namespace System.Security.Cryptography.X509Certificates , but it only handles existing certificates, not certificate requests. Can anyone give me an hint about it? Thanks in advance. 回答1: There is a way, the CertEnroll library which comes with Windows (although I can't say how far back it's been there) allows you to load certificate requests and have them parsed. First you need

问题 I am trying to generate a CSR (Certificate Signing Request) in an embedded device. I have implemented some OpenSSL functions in one embedded device. Unfortunately I only have a few functions available. So far I've been able to generate an RSA private key and now I need to generate the CSR. My library does NOT have any of the functions such as X509_REQ_new() , X509_REQ_get_subject_name() etc. Therefore I'm building the CSR by means of creating a DER file directly. The CSR in DER format is

问题 I'm trying to generate a CSR in Python without using OpenSSL. If someone could point in the right direction, I'd be very grateful. 回答1: I assume you don't want to use the command line openssl itself and a Python lib is ok. Here is an helper function I wrote to create a CSR. It returns the private key from the generated key pair and the CSR. The function depends on pyOpenSSL.crypto. def create_csr(self, common_name, country=None, state=None, city=None, organization=None, organizational_unit

Java - sign certificate programmatically without BC

问题 I am struggling with code that allows me to generate and sign certificates from java code without using keytool. Additionally due to dependency problems and incompatibilities i am unable to use bouncycastle libraries. So far I found working code to generate CSR with given parameters, and it seems to work (at least the openssl tools verify that it is indeed a valid CSR) the code I found is here: http://www.journaldev.com/223/generating-a-certificate-signing-request-using-java-api It works with

Can a Cert be issued without a CSR and using old Private Key

I'm confused about something in the SSL renewal process using WHM/cPanel for an existing Comodo Extended Validation cert. We have been issued a replacement certificate by Comodo without - I believe - every submitting a CSR for them. I say "I believe" because there are 3 people with access to WHM for this server, but I'm assured that no one has been fiddling in the last year. Does this sound possible? CAN a cert be supplied without a CSR if it's a replacement? I will attempt to get hold of Comodo but being a weekend, and seeing that the old cert runs out in a day I thought I'd consult the
