S3-Upload is a simple helper for creating a signed S3 upload policy, useful for allowing untrusted 3rd parties to upload to your bucket. Through, for example, a HTML form.
$ gem install s3-upload require 's3-upload' S3Upload.access_key_id = ... S3Upload.secret_access_key = ... S3Upload.bucket = 'my-upload-bucket' S3Upload.default_key_prefix = 'uploads/'
upload = S3Upload.new( :key_prefix => Time.now.to_s, :expiration_date => 1.year.from_now # Default is 1 hour ) render :json => upload
