Introduction

"An investment in knowledge always pays the best interest." -- Benjamin Franklin

Greetings and Salutations,

I deliver solutions to clients based on open-source technology. My professional interests center around the political, financial, and technical issues involved in the adoption of open-source into business. Other than that, all I am interested in is trying to make my wife smile.

SSL Certificates on Server

To setup postgresql to use SSL for connection set:

• ssl = on in postgresql.conf

• Create the server.key and server.crt files in "/var/lib/postgresql/<version>/main/"

Generate self-signed certificate for testing

%>openssl req -new -text -out server.req

Remove password

%>openssl rsa -in privkey.pem -out server.key
%>rm privkey.pem

Generate certificate:

%>openssl req -x509 -in server.req -text -key server.key -out server.crt
%>chmod og-rwx server.key

OpenSSL

Generate a Private Key

%>openssl genrsa -des3 -out server.key 1024

Generate a Certificate Signing Request

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

Remove Passphrase From Key

%>openssl rsa -in server.key -out server.key.nocrypt

Generate a Self Signed Certificate

%>openssl x509 -req -years 10 -in server.csr -signkey server.key.nocrypt -out server.crt
