UrlAuthenticator
A library to sign and verify signed URLs.
Usage
require "url_authenticator"
url = "http://example.com"
signed_url = UrlAuthenticator.sign(url, "your_secret")
# => "http://example.com?expires=1323787739&signature=c064a2cbda335ed784387ad69abd1880"
UrlAuthenticator.verify(signed_url, "your_secret") # => true
# If you want to extend expire period (20 minutes default):
expires_at = Time.now + 40 * 60
signed_url = UrlAuthenticator.sign(url, "your_secret", expires_at)
# => "http://example.com?expires=1323789137&signature=813b0e16bd5bc3618dd84d2274e9c212"
# If you want to use different time for expiration verification (default Time.now):
now = Time.new(2000, 7, 7, 12, 30)
UrlAuthenticator.verify(signed_url, "your_secret", now) # => true
