Self signed certificates using OpenSSL

Use the following command to generate a self-signed x509 certificate (mycert.pem), which is valid for 365 days and an RSA key (mykey.pem) of length 1024.

openssl req -x509 -nodes -days 365 -newkey rsa:1024 \
-keyout mykey.pem -out mycert.pem

Then you have to answer few questions. The information you provide by answering these questions will be stored in the certificate.

Country Name (2 letter code) [AU]:
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, YOUR name) []:
Email Address []:

That's it !!!
