Download private file from S3 using bash

Question

I am trying to get the following bash script to work (copied from http://curl.haxx.se/mail/archive-2014-10/0006.html#replies):

#!/bin/sh 
file=path/to/file          


        

Answer 1

After way too much time spent on this I finally got it to work:

This line:

signature=`/bin/echo -n "$stringToSign" | openssl sha1 -hmac ${s3Secret} -binary | base64`

is missing an 'e':

signature=`/bin/echo -en "$stringToSign" | openssl sha1 -hmac ${s3Secret} -binary | base64`

In other words, characters weren't being escaped before the string was signed.

As an aside, I also learned that for get requests, the content type is meaningless.
