Creating self signed certificatePosted: January 14, 2016
Again this is more an aide memoire.
Whilst waiting for my real SSL certificates to be create I wanted to continue my configuration of the server that I am building.
I therefore wanted a self signed certificate to try the config.
mkdir ~/sslselfsign cd ~/sslselfsign openssl genrsa -des3 -passout pass:x -out server.pass.key 2048
openssl rsa -passin pass:x -in server.pass.key -out server.key
rm -f server.pass.key
openssl req -new -key server.key -out server.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.
Country Name (2 letter code) [XX]:GB
State or Province Name (full name) :County_Name
Locality Name (eg, city) [Default City]:City_Name
Organization Name (eg, company) [Default Company Ltd]:Comany_Name
Organizational Unit Name (eg, section) :IT
Common Name (eg, your name or your server’s hostname) :xxxx.xxxxx.com
Email Address :
Please enter the following ‘extra’ attributes
to be sent with your certificate request
A challenge password :
An optional company name :
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
you should now have 3 files
