Generating a Self-Signed SSL Cert

Published on May 11, 2007

I have the need to generate an SSL cert (Apache2) about once every 3 months. And since I'm cheap, I don't ever actually *buy* one, I just self-sign it. And every time I forget the commands needed. So, here they are, for my reference only.

1) Generate Private Key

openssl genrsa -des3 -out server.key 1024

2) Generate a CSR

openssl req -new -key server.key -out server.csr

3) Remove passphrase

cp server.key server.key.org
openssl rsa -in server.key.org -out server.key

4) Generate Self-Signed Cert

openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
