CSR Requests – OpenSSL

Generate a Private Key with OpenSSL

openssl genrsa -out wildcard.jasonosull.com.key 2048

Then generate your CSR from the Private Key

openssl req -new -key wildcard.jasonosull.com.key -out wildcard.jasonosull.com.csr

You will then be asked a series of questions about your Organisation, State/location and a Common Name (CN)
Or you can use the one liner and fill the information

openssl req -new -newkey rsa:2048 -nodes -keyout wildcard.jasonosull.com.key -out wildcard.jasonosull.com.csr -subj "/C=IE/ST=Leinster/L=Dublin/O=Jasonosull Inc/OU=IT/CN=*.jasonosull.com"

Verify Your Certificate Request,

openssl req -in wildcard.jasonosull.com.csr -noout -text
