It would seem like the -addext parameter with "subjectAltName=" has a limited number of allowed characters. The following exports the two subjectAltName extensions as requested. openssl req -new -key key1.key -out req.csr -subj "/C=CA/ST openssl rsa -passin pass:abcdefg-in privkey.pem -out waipio.ca.key. Create an X.509 digital certificate from the certificate request. The following command line creates a certificate signed with the CA private key. The certificate is valid for 365 days. openssl x509 -in waipio.ca.cert.csr -out waipio.ca.cert -req -signkey waipio.ca.key -days 365 Feb 17, 2018 · There are numerous articles I’ve written where a certificate is a prerequisite for deploying a piece of infrastructure. This article will guide you through creating a trusted CA (Certificate Authority), and then using that to sign a server certificate that supports SAN (Subject Alternative Name). openssl x509 issues a certificate from a CSR. This is where -days should be specified. But: openssl req -x509 combines req and x509 into one; it generates a CSR and signs it, issuing a certificate in one go. That's why req supports the -days flag, as it passes it internally to the x509 command. RUN openssl req -x509 -sha256 -nodes -newkey rsa:4096 -days 365 -keyout /tmp/localhost.key -out /tmp/localhost.crt -subj '/CN=localhost' New working code: 🎉 RUN touch ~/.rnd RUN openssl req -x509 -sha256 -nodes -newkey rsa:4096 -days 365 -keyout /tmp/localhost.key -out /tmp/localhost.crt -subj '/CN=localhost' Hope it helps! 👍 Jul 22, 2020 · openssl req -new -key mydomain.com.key -out mydomain.com.csr Method B (One Liner) This method generates the same output as Method A but it's suitable for use in your automation :) . openssl req -new -sha256 -key mydomain.com.key -subj "/C=US/ST=CA/O=MyOrg, Inc./CN=mydomain.com" -out mydomain.com.csr

when you are using the openssl CA (strangely enough: openssl ca) command, you can give it numerous options, including which Subject value to use (the -subj argument), and which extensions to use (via the -extfile and -extensions arguments).

openssl req -nodes -sha256 -newkey rsa: 2048-keyout example.com.private-key -out example.com.csr -subj '/C=GB/L=London/O=Example Inc/CN=example.com' Now here's a full OpenSSL command that generates all the info you would see on an EV certificate: $ openssl req -x509 -newkey rsa:2048 -out server.crt -keyout server.key -subj /CN=localhost However, I prefer to fill in at least the organization and organizational unit as documentation in case I ever have to determine what or where I created this certificate for in the first place. $ openssl genrsa -out ca.key 2048 $ openssl req -new -x509 -days 3650 -key ca.key -out ca.crt -subj "/CN=my private CA" ここでは、ca.keyがCAの秘密鍵、ca.crtがCA証明書となる。 また、-daysオプションを使って有効期限を約10年後に指定している。 openssl req -newkey rsa:2048 -nodes -keyout privkey.pem -x509 -days 36500 -out certificate.pem If you want to passphrase the private key generated in the command above, omit the -nodes (read: "no DES") so it will not ask for a passphrase to encrypt the key.

Later, the alias openssl-cmd(1) was introduced, which made it easier to group the openssl commands using the apropos(1) command or the shell's tab completion. In order to reduce cluttering of the global manual page namespace, the manual page entries without the 'openssl-' prefix have been deprecated in OpenSSL 3.0 and will be removed in OpenSSL

OpenSSL Command to Generate Private Key openssl genrsa -out yourdomain.key 2048 OpenSSL Command to Check your Private Key openssl rsa -in privateKey.key -check OpenSSL Command to Generate CSR. If you have generated Private Key: openssl req -new -key yourdomain.key -out yourdomain.csr. Once you execute this command, you’ll be asked additional Oct 30, 2014 · OpenSSL CSR with Alternative Names one-line. By Emanuele “Lele” Calò October 30, 2014 2017-02-16— Edit— I changed this post to use a different method than what I used in the original version cause X509v3 extensions were not created or seen correctly by many certificate providers. The OpenSSL commands are a bit opaque and it's going to take me a few days or weeks to figure out this again, and perhaps someone is more familiar with OpenSSL than I am (not familiar at all, learned this once then forgot) and knows how to do this better. OpenSSL を用いて CSR を作成する方法. 秘密鍵を作成し、それから CSR を作成するには次のように、openssl genrsa と openssl req を利用できます。 $ openssl genrsa -out foo.key.pem 2048 $ openssl req -sha256 -new -key foo.key.pem -out foo.csr.pem Jul 16, 2020 · Run the following OpenSSL command to generate your private key and public certificate. Answer the questions and enter the Common Name when prompted. openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem
