Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from

#!/bin/bash

function startFw {
        #Some ban
        function banFw {
                /sbin/iptables -A INPUT -s $1 -j DROP
        }
        banFw 41.228.12.228     #brute force ssh
        banFw 220.247.238.16    #brute force ssh

# You cannot start postfix in some foreground mode and 
# it's more or less important that docker doesn't kill 
# postfix and its chilren if you stop the container.

# Use this script with supervisord and it will take
