Organization Name (eg, company) :Acme Inc State or Province Name (full name) :California If you enter '.', the field will be left blank. There are quite a few fields but you can leave some blankįor some fields there will be a default value, What you are about to enter is what is called a Distinguished Name or a DN. You will be prompted to fill-in various fields: You are about to be asked to enter information that will be incorporated This command will save the CSR to the my.csr file. Now we will create the Certificate Signing Request (CSR): openssl req -new -key my.key -out my.csr In this example we will use create an RSA 4096 key (current best practice) and store it in the file my.key: openssl genrsa -out my.key 4096 STEP 3 – Generate CSR To create the key pair you need to decide upon a cryptographic algorithm (RSA is the most common) and the bit-size of the key. The private and public key pair is needed to sign the CSR. To install OpenSSL on Ubuntu and other Debian based Linux using apt-get, run: apt-get install openssl STEP 2 – Create Key Pair To install OpenSSL on Red Hat based Linux which using yum, run the command: yum install openssl If it’s not installed, you’ll get an error like “Command not found”. If openssl is installed you will see the OpenSSL version information. To get started you need to see if you already have OpenSSL installed. The traditional process of creating a trusted certificate on Linux is based on using the OpenSSL command line tool available with nearly all Linux distributions such as Red Hat Enterprise Linux, CentOS Linux, Ubuntu Linux, Debian Linux, SuSe Linux, and many others.
