Any examples on how to use this library with "signed" requests?

[nightsurge]

I have a need to sign some requests for certain API's I am integrating with. I love this library, but so far I've not seen any out of the box support for a signing routine or middle-ware. Is there any known support for, or examples of doing a signed request using HTTP.rb?

Thoughts?

I admit I'm very new to this concept of having to sign the requests before sending. Here is what I found below, just looking for the easiest/best option when using HTTP.rb gem as well:
