Using curl with custom CA certificates

This document describes how to use curl with both custom and official CA SSL certificates.

Prerequisite

You would need first to install curl , see http://curl.haxx.se/docs/install.html. Using a package manager such as yum, brew, ... for your platform should be the easiest though.

Example for Mac OS:

awk & sed cheetsheet

Extract lines between start and end

between() { sed -n "/^$1/,/^$2/p" | sed '1d;$d'; }

Also:

awk '/^START=A$/,/^END$/ { print }’ data

SSL cheetsheet

Encode file with password

alias enc='openssl enc -e -aes128 -base64 -pass "env:PASS"'

Decode file with password

alias dec='openssl enc -d -aes128 -base64 -pass "env:PASS"'

Processing JSON using jq

jq is useful to slice, filter, map and transform structured json data.

Installing jq

On Mac OS

brew install jq
