openssl generate csr with san ip

The command below will export the Certificate Signing Request (CSR) into myserver.csr file. The private key is stored with no passphrase. Confirm the CSR using this command: openssl req -text -noout -verify -in example.com.csr. If you want to issue a CSR with a SAN attribute, you need to pass the same -ext argument to 'keytool -certreq'. Generate a private key: $ openssl genrsa -out san.key 2048 && chmod 0600 san.key. To create a Certificate Signing Request (CSR) and key file for a Subject Alternative Name (SAN) certificate with multiple subject alternate names, complete the following procedure: Create an OpenSSL configuration file (text file) on the local computer by editing the fields to the company requirements. First, create another private key and then generate the CSR using the following commands: openssl genrsa -out localhost.key 2048. openssl req -new -key localhost.key -out localhost.csr -config localhost.cnf -extensions v3_req. I have added this line to the [req_attributes] section of my openssl.cnf:. Below are the basic steps to use OpenSSL and create a certificate request using a config file and a private key. Change alt_names appropriately. The preceding is contingent on your OpenSSL configuration enabling the SAN extensions (v3_req) for its req commands, in addition to the x509 commands. Generate SSL certificates with IP SAN. GitHub Gist: instantly share code, notes, and snippets. In the first example, i’ll show how to create both CSR and the new private key in one command. The next most common use case of OpenSSL is to create certificate signing requests for requesting a certificate from a certificate authority that is trusted. You are welcomed to send the CSR to your favorite CA. Generate CSR from Windows Server with SAN (Subject Alternative Name) August 9, 2019 August 9, 2019 / By Yong KW Please refer to the steps below on how to generate CSR from Windows Server with SAN (Subject Alternative Name) as SSL certificates generated from IIS do not contain a SAN Aside. keytool -certreq -keystore server.jks -storepass protected -file myserver.csr Take-aways. In this article you’ll find how to generate CSR (Certificate Signing Request) using OpenSSL from the Linux command line, without being prompted for values which go in the certificate’s subject field.. Below you’ll find two examples of creating CSR using OpenSSL.. Java's keytool creates a keypair in the form of a self-signed certificate in the key store, and the SAN attribute goes into that self-signed certificate. You will first create/modify the below config file to generate a private key. subjectAltName = Alternative subject names This has the desired effect that I am now prompted for SANs when generating a CSR: Create a configuration file. In /etc/ssl/openssl.cnf, you may need to … Then you will create a .csr. Beware that the above command does not create a CSR. $ cat << EOL > san.conf [ req ] default_bits = 2048 default_keyfile = san.key #name of the keyfile distinguished_name = req_distinguished_name req_extensions = req_ext [ req_distinguished_name ] countryName = Country Name (2 letter code) … This CSR is the file you will submit to a certificate authority to get back the public cert. I wish to configure OpenSSL such that when running openssl req -new to generate a new certificate signing request, I am prompted for any alternative subject names to include on the CSR.. Similar to the previous command to generate a self-signed certificate, this command generates a CSR. You should now have a better knowledge of what is SAN certificate and how to create SAN CSR $ touch myserver.key $ chmod 600 myserver.key $ openssl req -new -config myserver.cnf -keyout myserver.key -out myserver.csr This will create a 2048-bit RSA key pair, store the private key in the file myserver.key and write the CSR to the file myserver.csr. Use the generated certificate request to generate a new self-signed certificate with the specified IP address: openssl x509 -req -in req.pem -out new_cert.pem -extfile ./openssl.cnf -extensions v3_ca -signkey old_cert.pem openssl req -new -newkey rsa:2048 -nodes -out request.csr -keyout private.key.
