Show HN: Simple Gem generates AWS S3 Policy and Signature

[vinhnglx]

S3 accepts uploads via specially-crafted and pre-authorized HTML POST Form.

A simple gem will help you create two values: Signature and Policy - https://github.com/vinhnglx/s3-authorize

This gem is very useful when working with AngularJS file upload

Thanks for this. I find this useful.

I've been using this gist (https://gist.github.com/stefanneculai/deed108fad534d0db3ff) for my prototypes, but a require is way more productive.
