Use http://docs.aws.amazon.com/sdk-for-ruby/v3/api/Aws/CloudFront/UrlSigner.html instead. I don't plan to maintain this gem any more.

Sign AWS CloudFront URLs.

Add this line to your application's Gemfile:

gem 'cloud_front_signing'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cloud_front_signing

# Replace these for your specific AWS account/CloudFront configuration
private_key_string = IO.read("path/to/pk-123456789012.pem")
key_pair_id = "123456789012"

signer = CloudFrontSigning::Signer.new(private_key_string, key_pair_id)

unsigned_url = "https://distribution-id.cloudfront.net/private.zip"
options = {ending: 1.hour.from_now} # or, e.g. `Time.now + 3600` if you don't have activesupport
signed_url = signer.sign(unsigned_url, options)

Valid options:

• ending: required, the signed URL will only be accessible until this time, a Time object or a String parseable by Time.parse
• resource: the base URL including your query strings, if any, but excluding the CloudFront Policy, Signature, and Key-Pair-Id parameters, uses unsigned_url by default
• starting: the signed URL will only be accessible after this time, a Time object or a String parseable by Time.parse
• ip_range: the signed URL will only be accessible by IP addresses in this range, a CIDR string, e.g. 10.1.2.3/32, 10.2.3.0/24, and so on.

Specifying starting and/or ip_range will cause the signed URL to include a custom policy which is longer.
