openssl req -out sslcert.csr -newkey rsa:2048 -nodes -keyout private.key -config san.cnf This will create sslcert.csr and private.key in the present working directory. You have to send sslcert.csr to certificate signer authority so they can provide you a certificate with SAN. How to verify CSR for SAN SAN Zertifikate mit OpenSSL erstellen. Wie immer beginnen wir mit der Erstellung eines privaten Schlüssels. openssl genrsa -out Apache.key 4096. Zur Erstellung eines Zertifikats-Requests benötigen wir eine minimale Konfigurationsdatei. Dazu kopieren wir diesen Satz in eine Textdatei und benennen diese in reg.conf um Because we want to include a SAN (Subject Alternative Name) in our CSR (and certificate), we need to use a customized openssl.cnf file. While you could edit the 'openssl req' command on-the-fly with a tool like 'sed' to make the necessary changes to the openssl.cnf file, I will walk through the step of manually updating the file for clarity Next we will use openssl to generate our Certificate Signing Request for SAN certificate. # openssl req -new -key priv.key -out ban21.csr -config server_cert.cnf. Since we have used prompt=no and have also provided the CSR information, there is no output for this command but our CSR is generate Zu­sätz­li­che Do­mainein­trä­ge lan­den in dem er­wei­ter­ten SAN-Feld. opens­sl fragt bei der re­gu­lä­ren Er­zeu­gung eines CSR keine Daten für sol­che Ein­trä­ge ab.

The preceding is contingent on your OpenSSL configuration enabling the SAN extensions (v3_req) for its req commands, in addition to the x509 commands. In /etc/ssl/openssl.cnf, you may need to uncomment this line: # req_extensions = v3_req # The extensions to add to a certificate reques If no SAN is needed to be added, remove the red lines. If more SAN names are needed, add more DNS lines in the [alt_names] section. Run OpenSSL command. The command generates the certificate (-out) and the private key (-keyout) by using the configuration file (-config). The -nodes parameter avoids setting a password to the private key Firefox & Chrome now require the subjectAltName (SAN) X.509 extension for certificates. Please provide a way to specify the SAN interactively (along the CN) when generating certs & reqs using the openssl command line tool (openssl req). Currently one has to do some ugly trickery to generate a self-signed certificate Only freaking way I had to make the SAN thing work. Security by sorcery! 1. SAN env var : didn't work 2./etc/ssl/openssl.cnf-> subjectAltName=${ENV::SAN}: didn'twork The command to make it work (OpenSSL 1.1.1f, but trust me, your openssl won't do the same) was: openssl req -newkey rsa:2048 -nodes -keyout server.key -x509 -days 365 -out server.crt -subj /CN=localhost -addext subjectAltName.

openssl x509 -req -days 3650 -in server.csr -signkey server.key -out server.crt -extensions v3_req -extfile openssl.cnf. We'll also need to add a config file. Copy your operating system's openssl.cnf - on ubuntu it is in /etc/ssl - to your working directory, and make a couple of tweaks to it. We need to do this because the openssl tool will not prompt for these attributes. We'll need to make. openssl req -new -key yourdomain.key -out yourdomain.csr. After entering the command, you will be asked series of questions. Your answers to these questions will be embedded in the CSR. Answer the questions as described below: Country Name (2 letter code) The two-letter country code where your company is legally located. State or Province Name (full name) The state/province where your company. # OpenSSL configuration to generate a new key with signing requst for a x509v3 # multidomain certificate # # openssl req -config bla.cnf -new | tee csr.pem # or # openssl req -config bla.cnf -new -out csr.pem [ req ] default_bits = 4096 default_md = sha512 default_keyfile = key.pem prompt = no encrypt_key = no # base request distinguished_name = req_distinguished_name # extensions req.

Einrichtung des öffentlichen Schlüssels für den Apache-Server (OpenSSL) Zur Einrichtung des Zertifikatsantrags (öffentlichen Schlüssels) und Privatschlüssels wird die Software OpenSSL benutzt, die Sie meistens unter /usr/local/ssl/bin finden. Im ersten Schritt erzeugen Sie das Schlüsselpaar (key pair). Schreiben Sie in die Kommandozeile ein openssl req -text -noout -verify -in server.example.com.csr. Scroll down and look for the X509v3 Subject Alternative Name section. Now, if you want to include all those SANs, then the openssl.cnf you used to sign will have to have all those SANs already defined. Plus you can add some more if you want (like, if someone forgot to request www.foo.com as a SAN). Let's assume that you're just. openssl req -new -key <private key file name>.key -config <DomainName>.cnf -out <csr file name>.csr Submit your CSR. Open your .csr file in a text editor (Never use Notepad) and copy the contents. Then submit it to an authority (internal for our sake) and then down load your certificate as a base64. If you are going to submit it to an online authority, use a repeatable authority like DigiCert. Verify the certificate has an IP SAN by running the following command: openssl x509 -in domain.crt -noout -text. This will output the contents of the cert for you to inspect. While there is a lot there, you are looking for a couple lines like this: X509v3 Subject Alternative Name: IP Address: Now you can install the self-signed.

Here's how to create a self signed certificate with SAN using openssl. First, lets create a root CA cert using createRootCA.sh: #!/usr/bin/env bash mkdir ~/ssl/ openssl genrsa -des3 -out ~/ssl/rootCA.key 2048 openssl req -x509 -new -nodes -key ~/ssl/rootCA.key -sha256 -days 1024-out ~/ssl/rootCA.pem. Next, create a file createselfsignedcertificate.sh: #!/usr/bin/env bash sudo openssl req -new. $ openssl req -key domain.key -new -out domain.csr You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank.

How to Create a CSR and Key File for a SAN Certificate
